Bone Conduction: Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.Ear Ossicles: A mobile chain of three small bones (INCUS; MALLEUS; STAPES) in the TYMPANIC CAVITY between the TYMPANIC MEMBRANE and the oval window on the wall of INNER EAR. Sound waves are converted to vibration by the tympanic membrane then transmitted via these ear ossicles to the inner ear.Scala Tympani: The lower chamber of the COCHLEA, extending from the round window to the helicotrema (the opening at the apex that connects the PERILYMPH-filled spaces of scala tympani and SCALA VESTIBULI).Hearing Loss, Conductive: Hearing loss due to interference with the mechanical reception or amplification of sound to the COCHLEA. The interference is in the outer or middle ear involving the EAR CANAL; TYMPANIC MEMBRANE; or EAR OSSICLES.Ear, Middle: The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.Neural Conduction: The propagation of the NERVE IMPULSE along the nerve away from the site of an excitation stimulus.Bone and Bones: A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.Hearing Aids: Wearable sound-amplifying devices that are intended to compensate for impaired hearing. These generic devices include air-conduction hearing aids and bone-conduction hearing aids. (UMDNS, 1999)Audiometry, Pure-Tone: Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli.Heart Conduction System: An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.Auditory Threshold: The audibility limit of discriminating sound intensity and pitch.Bone Remodeling: The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.Bone Density: The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.Bone Resorption: Bone loss due to osteoclastic activity.Bone Marrow: The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.Voice: The sounds produced by humans by the passage of air through the LARYNX and over the VOCAL CORDS, and then modified by the resonance organs, the NASOPHARYNX, and the MOUTH.Voice Disorders: Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA. Voice disorders can be caused by organic (anatomical), or functional (emotional or psychological) factors leading to DYSPHONIA; APHONIA; and defects in VOICE QUALITY, loudness, and pitch.Brain-Computer Interfaces: Instrumentation consisting of hardware and software that communicates with the BRAIN. The hardware component of the interface records brain signals, while the software component analyzes the signals and converts them into a command that controls a device or sends a feedback signal to the brain.Forehead: The part of the face above the eyes.Congresses as Topic: Conferences, conventions or formal meetings usually attended by delegates representing a special field of interest.Cochlear Implants: Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers.

Helv., the Swiss Pharmacopoeia). They differ from FORMULARIES in that they are far more complete: formularies tend to be mere listings of formulas and prescriptions.Cochlear Implantation: Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.International Cooperation: The interaction of persons or groups of persons representing various nations in the pursuit of a common goal or interest.United States Food and Drug Administration: An agency of the PUBLIC HEALTH SERVICE concerned with the overall planning, promoting, and administering of programs pertaining to maintaining standards of quality of foods, drugs, therapeutic devices, etc.Cellular Phone: Analog or digital communications device in which the user has a wireless connection from a telephone to a nearby transmitter. It is termed cellular because the service area is divided into multiple "cells." As the user moves from one cell area to another, the call is transferred to the local transmitter.Blogging: Using an INTERNET based personal journal which may consist of reflections, comments, and often hyperlinks.Music: Sound that expresses emotion through rhythm, melody, and harmony.Music Therapy: The use of music as an adjunctive therapy in the treatment of neurological, mental, or behavioral disorders.Dictionaries, MedicalOsteogenesis, Distraction: Bone lengthening by gradual mechanical distraction.

Ear and hearing in Sphenodon punctatus. (1/67)

Observations on Sphenodon punctatus have revealed new features of the anatomy of the ear,and measurements in a living specimen by means of cochlear potentials show the form and level of this ear's performance in sound reception. For an animal lacking an external ear opening and a functional tympanic membrane, the sensitivity of from 100-900 Hz is surprisingly good in low tones with peak response around 200-400 Hz. The inner ear is well developed, with a tectorial membrane connected to a tectorial plate that extends throughout the cochlea. The best region of sensitivity agrees well with the main frequency components of the animal's vocalizations.  (+info)

Isolating the auditory system from acoustic noise during functional magnetic resonance imaging: examination of noise conduction through the ear canal, head, and body. (2/67)

Approaches were examined for reducing acoustic noise levels heard by subjects during functional magnetic resonance imaging (fMRI), a technique for localizing brain activation in humans. Specifically, it was examined whether a device for isolating the head and ear canal from sound (a "helmet") could add to the isolation provided by conventional hearing protection devices (i.e., earmuffs and earplugs). Both subjective attenuation (the difference in hearing threshold with versus without isolation devices in place) and objective attenuation (difference in ear-canal sound pressure) were measured. In the frequency range of the most intense fMRI noise (1-1.4 kHz), a helmet, earmuffs, and earplugs used together attenuated perceived sound by 55-63 dB, whereas the attenuation provided by the conventional devices alone was substantially less: 30-37 dB for earmuffs, 25-28 dB for earplugs, and 39-41 dB for earmuffs and earplugs used together. The data enabled the clarification of the relative importance of ear canal, head, and body conduction routes to the cochlea under different conditions: At low frequencies (< or =500 Hz), the ear canal was the dominant route of sound conduction to the cochlea for all of the device combinations considered. At higher frequencies (>500 Hz), the ear canal was the dominant route when either earmuffs or earplugs were worn. However, the dominant route of sound conduction was through the head when both earmuffs and earplugs were worn, through both ear canal and body when a helmet and earmuffs were worn, and through the body when a helmet, earmuffs, and earplugs were worn. It is estimated that a helmet, earmuffs, and earplugs together will reduce the most intense fMRI noise levels experienced by a subject to 60-65 dB SPL. Even greater reductions in noise should be achievable by isolating the body from the surrounding noise field.  (+info)

Nievergelt-Pearlman syndrome with impairment of hearing. Report of three cases in a family. (3/67)

Three cases of the Nievergelt-Pearlman syndrome occurring in a family are presented. In addition to the major features of the syndrome (symphalangism, carpal fusion, atypical club foot with massive tarsal fusion, and congenital dislocation of the head of the radius), all three patients exhibited conductive deafness, which had not been recorded in previous reports. The clinical findings strongly suggested that the loss of hearing was due to fusion of the ossicles of the middle ear.  (+info)

Inner ear damage in children due to noise exposure from toy cap pistols and firecrackers: a retrospective review of 53 cases. (4/67)

This retrospective study presents the findings of inner ear damage documented in 53 children exposed to impulsive sound emitted by toy weapons and firecrackers. There were 49 boys and four girls aged between four and fourteen years. Thirty-nine children were affected unilaterally while fourteen had bilateral hearing loss (total of 67 ears). Most of the hearing loss (>70%) was sensorineural high frequency hearing loss, while only nine out of the 67 injured ears had sensorineural mid frequency hearing loss. Seven children sustained a traumatic ear drum perforation. Dizziness or tinnitus was reported by twenty children, with pathological ENG findings in four of them. This paper re-emphasizes the possibility of inner ear damage in children from exposure to noisy toys.  (+info)

Vestibular activation by bone conducted sound. (5/67)

OBJECTIVE: To examine the properties and potential clinical uses of myogenic potentials to bone conducted sound. METHODS: Myogenic potentials were recorded from normal volunteers, using bone conducted tone bursts of 7 ms duration and 250-2000 Hz frequencies delivered over the mastoid processes by a B 71 clinical bone vibrator. Biphasic positive-negative (p1n1) responses were recorded from both sternocleidomastoid (SCM) muscles using averaged unrectified EMG. The best location for stimulus delivery, optimum stimulus frequency, stimulus thresholds, and the effect of aging on evoked response amplitudes and thresholds were systematically examined. Subjects with specific lesions were studied. Vestibular evoked myogenic potentials (VEMP) to air conducted 0.1 ms clicks, 7 ms/250-2000 Hz tones, and forehead taps were measured for comparison. RESULTS: Bone conducted sound evoked short latency p1n1 responses in both SCM muscles. Ipsilateral responses occurred earlier and were usually larger. Mean (SD) p1 and n1 latencies were 13.6 (1.8) and 22.3 (1.2) ms ipsilaterally and 14.9 (2.1) and 23.7 (2.7) ms contralaterally. Stimuli of 250 Hz delivered over the mastoid process, posterosuperior to the external acoustic meatus, yielded the largest amplitude responses. Like VEMP in response to air conducted clicks and tones, p1n1 responses were absent ipsilaterally in subjects with selective vestibular neurectomy and preserved in those with severe sensorineural hearing loss. However, p1n1 responses were preserved in conductive hearing loss, whereas VEMP to air conducted sound were abolished or attenuated. Bone conducted response thresholds were 97.5 (3.9) dB SPL/30.5 dB HL, significantly lower than thresholds to air conducted clicks (131.7 (4.9) dB SPL/86.7 dB HL) and tones (114.0 (5.3) dB SPL/106 dB HL). CONCLUSIONS: Bone conducted sound evokes p1n1 responses (bone conducted VEMP) which are a useful measure of vestibular function, especially in the presence of conductive hearing loss. For a given perceptual intensity, bone conducted sound activates the vestibular apparatus more effectively than air conducted sound.  (+info)

Middle ear dynamics in response to seismic stimuli in the Cape golden mole (Chrysochloris asiatica). (6/67)

The hypertrophied malleus in the middle ear of some golden moles has been assumed to be an adaptation for sensing substrate vibrations by inertial bone conduction, but this has never been conclusively demonstrated. The Cape golden mole (Chrysochloris asiatica) exhibits this anatomical specialization, and the dynamic properties of its middle ear response to vibrations were the subjects of this study. Detailed three-dimensional middle ear anatomy was obtained by x-ray microcomputed tomography (muCT) at a resolution of 12 microm. The ossicular chain exhibits large malleus mass, selective reduction of stiffness and displacement of the center of mass from the suspension points, all favoring low-frequency tuning of the middle ear response. Orientation of the stapes relative to the ossicular chain and the structure of the stapes footplate enable transmission of substrate vibrations arriving from multiple directions to the inner ear. With the long axes of the mallei aligned parallel to the surface, the animal's head was stimulated by a vibration exciter in the vertical and lateral directions over a frequency range from 10 to 600 Hz. The ossicular chain was shown to respond to both vertical and lateral vibrations. Resonant frequencies were found between 71 and 200 Hz and did not differ significantly between the two stimulation directions. Below resonance, the ossicular chain moves in phase with the skull. Near resonance and above, the malleus moves at a significantly larger mean amplitude (5.8+/-2.8 dB) in response to lateral vs vertical stimuli and is 180 degrees out of phase with the skull in both cases. A concise summary of the propagation characteristics of both seismic body (P-waves) and surface (R-waves) is provided. Potential mechanisms by which the animal might exploit the differential response of the ossicular chain to vertical and lateral excitation are discussed in relation to the properties of surface seismic waves.  (+info)

Craniocentric body-sway responses to 500 Hz bone-conducted tones in man. (7/67)

Whole-body responses evoked by bone-conducted sound, a stimulus known to activate vestibular afferents, were recorded in standing subjects deprived of vision. With the head facing forward, unilateral mastoid vibration (500 Hz, 2 s, 136 dB force level) produced an oblique body sway with a consistent lateral component away from the stimulated ear and an average forward component. The side of stimulation had a powerful influence on the direction but not the magnitude of sway. Individuals' mean response directions were significantly clustered between subjects, as well as within subjects for 12 of 16 subjects when tested on five occasions. Single trial analysis did not reveal any habituation of the response. To investigate whether muscle spindle activation might be responsible for the response, vibration was applied directly over posterior and anterior neck muscles and tendons. This generally produced responses that were smaller and with different direction characteristics than with mastoid vibration. In contrast, stimulation over the temporal fossa produced responses similar in magnitude and direction to mastoid stimulation. When the head was turned in yaw to face in different directions the sway response changed direction by the same amount but with no change in magnitude, suggesting response organization in a craniocentric reference frame. Whole-body sway evoked by 500 Hz vibration delivered over sites close to the ear is thus likely to represent a vestibular-evoked balance response. When compared with sway responses evoked by 500 Hz vibration of the left temporal fossa, responses to 1 mA left cathodal galvanic vestibular stimulation were of similar magnitude, yet significantly different in direction, suggesting differences in the end organ afferents activated by these two stimuli. This may enable investigation of previously inaccessible aspects of vestibular function in intact freely behaving human subjects.  (+info)

Superior Canal Dehiscence Syndrome. (8/67)

The Superior Canal Dehiscence Syndrome (SCDS) was first reported by Minor at. Al. (1998), and has been characterized by vertigo and vertical-torsional eye movements related to loud sounds or stimuli that change middle ear or intracranial pressure. Hearing loss, for the most part with conductive patterns on audiometry, may be present in this syndrome. We performed a literature survey in order to to present symptoms, signs, diagnostic and therapeutic approaches to the SCDS, also aiming at stressing the great importance of including this syndrome among the tractable cause of vertigo. We should emphasize that this is a recent issue, still unknown by some specialists. The Correct SCDS diagnosis, besides enabling patient treatment, precludes misdiagnosis and inadequate therapeutic approaches.  (+info)

One method of tinnitus treatment is to use sound masking devices that produce music, white noise, pink noise, or ambient sounds to distract from or cover tinnitus sounds.. Bone conduction headphones can be used as tinnitus maskers for those who find tinnitus relief with environmental/ambient sounds, music, or speech (eg, podcasts).. Furthermore, many tinnitus sufferers report that, since standard headphones generally block external noise, wearing them can make tinnitus sounds seem louder. Standard in-ear headphones can also worsen hearing loss and tinnitus. Using bone conduction headphones on the other hand, would likely remedy these issues as they leave the ears free and unblocked.. As every persons experience with and causality of tinnitus is different, it is always a good idea to speak with your healthcare provider who is treating you for tinnitus about using bone conduction headphones.. ...
Objective(s): When choosing a method to implant a transducer for direct bone conduction stimulation, several options are available with the trade-off being, among other aspects, between achieving a robust contact to the bone and keeping an open possibility for potential future explantation. The aim of this study is to compare how different attachment methods for direct bone conduction stimulation can affect the vibrations transmission to the cochleae. The ultimate goal is to gain more insights on the dynamical properties of the skull to apply them to the design and optimization of bone conduction devices for hearing rehabilitation. Study design: Experimental. Patients: Measurements were performed on four human heads. The tympanic membrane, the malleus and the incus were removed to expose the cochlear promontory on both sides of each subject. The subjects have not undergone any previous surgery as verified by visual inspection. Methods: Three different attachments are tested on eight sides: (A) flat

The headband (3) has its opposite ends carry a pair of head pads (5) held in abutting contact with opposite sides of the head. At least one of the head pads (5) carries both the bone conduction speaker (1) and the microphone (2).
The audiometric version is used in hearing clinics in combination with headphones to check function of middle ear/inner ear separately, as the vibration short circuits the middle ear and goes directly to the inner ear.. The conventional version is used to transmit speech, music, signals to the inner ear. A bone vibrator can therefore be part of a hearing aid when the patient has problems with the middle ear. The conventional version that Ortofon is offering at the moment is not designed for hearing aids but for transmitting music and speech.. Bone vibrators are also used when you want to keep the hearing canal free to hear what goes on around you and at the same time hearing e.g. communication through the bone vibrator.. ...

This ability to filter out extraneous sound and information is vital for paying attention and concentrating. John is not able to do this and every noise has the same importance or the same sound value.. John knows that he is supposed to be paying attention but other sounds, pieces of information or even thoughts keep intruding and demanding his attention. This has been an ongoing problem and good, prolonged attention has never properly developed.. One of the primary reasons for this is that John has an Auditory Processing difficulty described as hyper sensitivity to Bone Conduction - this was clearly seen when John completed a Listening Test.. We hear sounds in two ways, through Air Conduction i.e. our ears, and through Bone Conduction i.e. our bodies, (have you ever felt a sound in your body, perhaps the low bass sound in a disco, or the rumbling of lorry outside on the road? This is bone conduction). When the correct relationship between listening through Bone conduction and Air conduction ...
CENTENNIAL, Colo., Nov. 19, 2012 /PRNewswire/ -- Cochlear Americas announced today the introduction of the Cochlear Baha BIA400 series, which features a unique abutment surface technology - a hydroxyapatite layer - that enables a tight adherence between the soft tissue and the abutment. This technology is designed to minimize the need for soft tissue removal and simplify the surgical procedure.. Important benefits for patients are that the surgical procedure becomes less invasive and the soft tissue disruption can be minimized. This new technology is designed to provide bone conduction patients with better aesthetic outcomes than with conventional percutaneous abutments. Leaving the soft tissue intact may also result in significantly shorter surgery time, faster healing and increase the likelihood of normal post-operative skin sensation around the implant site.. ...

Absoprtion coefficient, Reflection coefficient and Impedance ratio are first measured using the impedance tube. Reverse calculation of these acoustical properties yield flow resistivity that is inverse of permeability. The method can measure, glass, carbon and hybrid lay ups of differing porosity values with ease. The impedance tube can be utilized to measure longitudinal and transverse permeability using the method described. Sized and unsized fibers are measured using this technique. Negligible variation in permeability is found due to the absence of sizing.. AB - An acoustical method of predicting permeability of orthotropic fibers is presented. The acoustical method ...
If you have any of these symptoms, you should see an audiologist to get an "audiometric evaluation." An audiometric evaluation (AE) is the term used to describe a diagnostic hearing test, performed by a licensed audiologist. An AE is not just pressing the button when you hear a "beep." Rather, an audiometric evaluation allows the audiologist to determine the type and degree of your hearing loss, and it tells the audiologist how well or how poorly you understand speech. After all, speech is the single most important sound, and the ability to understand speech is extremely important. The AE also includes a thorough case history (interview) as well as visual inspection of the ear canals and eardrum. The results of the AE are useful to the physician should the audiologist conclude that your hearing problem may be treated with medical or surgical alternatives ...

Implant stability can be seen as a combination of mechanical stability, which is the result of compressed bone holding the implant tightly in place, and biological stability, which is the result of new bone forming at the site of implantation and osseointegration. Mechanical stability is generally high immediately after implant placement and is decreasing with time. Biological stability, on the other hand, is non-existent immediately after placement and increases with time. The final stability level for an implant is the sum of the two. There is likely to be an initial decrease in stability followed by a subsequent increase as the implant becomes biologically stable. ISQ (implant Stability Quotient) is a measurement scale for use with the Resonance Frequency Analysis (RFA) method of determining implant stability ...

Google Glass has been on the minds of tech enthusiasts for over a year now, and today we finally have a glimpse of what Googles foray into wearable tech will produce. We saw an extraordinary demo of this technology at last years Google I/O conference, and rumors have been abounding since then. The Google Glass Explorer Edition has made its way into the FCC, providing a look at the design of the unit.. The hardware, which has been rumored to arrive this year, will be touting a Broadcom 2.4GHz 802.11 b/g WiFi radio thats been paired with a Bluetooth 4.0 + LE module. The FCC filing also references an "integral vibrating element that provides audio to the user via contact with the users head," indicating that the Google Glass Explorer Edition may incorporate a feature congruent to Googles bone conduction audio delivery system which was seen earlier in the month. The filing also states that the testing lab involved was able to view video with audio using the bone conduction technique.. The FCC ...
Overall, the Bluez 2 headphones from Aftershokz are a very impressive gadget. I had previously advocated not to use headphones on the bike again, unless I was on the rollers or turbo trainer; these have firmly changed that.

You dont need to worry about blocking out alerting traffic noise, and you dont need to worry about fumbling with your phone or iPod, as you try to change tracks. Theyre very well made, theyre sweat resistant, and they even have nice little additions like reflective strips that you can add to the rear band to aid visibility ...
In sensorineural hearing loss the ability to sense the tuning fork by both bone and air conduction is equally diminished, implying they will hear the tuning fork by air conduction after they can no longer hear it through bone conduction. This pattern is the same to what is found in people with normal hearing, but patients with sensorineural hearing loss will indicate that the sound has stopped much earlier. This can be revealed by the person administering the test (with normal hearing) placing the fork close to their own ear after the patient indicates that the sound has subsided, noting that the sound from the fork is still noticeable to a normal ear ...

We knew the right ear had a ruptured eardrum, but werent sure of the effect this would have on his hearing level. It turns out a conductive problem can be devastating to a kid with a moderate sensorineural loss. Nolan is testing at about 80dB across the board, with speech reception thresholds at 80dB. This is severe, and his hearing aid is pretty much useless for that ear at this point. We did do an unmasked bone conduction on that side and got speech thresholds of 45dB, so we are fairly positive the results are due to the hole in the eardrum.

Tinnitus is the presence of sound perceived as coming from the ears or head. It is most commonly reported as a ringing, but can also be described as buzzing, chirping, roaring, cricket, or many diverse sounds. Tinnitus can be caused by noise induced hearing loss, medical conditions, prescriptions, or even ear wax.. Tinnitus is often one of the first recognized symptoms of hearing loss. Seeing an audiologist is one of the most important steps in evaluating tinnitus as they are the primary specialty for assessing this disorder of hearing. Collaboration with otolaryngologists, physicians, psychologists, dentists, physical therapists and other medical professionals may be necessary to successfully manage tinnitus at times.. Tinnitus evaluations begin with a diagnostic audiometric evaluation and then go on to include pitch and loudness matching of the tinnitus as well. Treatment often begins with some degree of amplification but varies individually. Tinnitus affects everyone uniquely and our mission ...
Downloadable! This article introduces a U-statistic type process that is fashioned from a kernal which can depend on nuisance parameters. It is shown that this process can accommodate, in a straightforward manner, anti-symmetric kernels, which have proved useful for detecting changing patterns in the dynamics of time series, and weight functions. Weight functions have been shown to improve the power of test statistics employed to detect these changing patterns throughout the evaluation perios; early and late as well. Theory and related test statistics are developed here and applied to detection of structural breaks in linear regression models (LRM). This flexibility is exploited to develop tests to detect changes in intercept or slope in LRMs that are robust to changes in the rest of medal parameters. The statistics developed here are applied to detect changing patterns in mutual fund managers stock selecting ability over the period 2001 to 2010.

The effect of mastoid sclerosis on bone-conduction threshold sensitivity was assessed by retrospective comparison of audiologic data from 14 persons with unilateral mastoid sclerosis and 13 persons with normally pneumatized mastoids. All subjects with normal mastoids had unilateral sensorineural loss; most sclerotic mastoid subjects had normal hearing in the ear associated with a normally pneumatized mastoid and mixed or pure sensorineural loss on the sclerotic side. Mean interaural threshold differences and distributions of differences were similar for both groups. Sclerotic mastoids do not appear to have a significant effect on bone-conduction thresholds.. ...

Mixed hearing loss is a form of hearing loss in which a conductive hearing loss occurs with a sensorineural hearing loss (ASHA, n/d, http://www.asha.org/public/hearing/Mixed-Hearing-Loss/). Conductive hearing losses can be identified on the audiogram by an air-bone gap, whereas the bone conduction hearing test (symbols: , , ) and the air conduction hearing test (symbols: x O) are not at the same hearing levels. Sensorineural hearing losses have no bone-air gap and symbols (,, o) and (,, x) overlap. Mixed hearing losses have frequencies with both gaps and no gaps.

Patients with chronic ear infection where the drum and/or the small bones in the middle ear are damaged often have hearing loss, but difficulties in using a hearing aid fitted in the ear canal. Direct bone conduction through a vibrator attached to a skin-penetrating implant addresses these disadvantages.. In 1977, the first three patients were implanted with a bone-conduction hearing solution by Anders Tjellström at the Ear, Nose, and Throat Department at Sahlgrenska University Hospital in Gothenburg, Sweden. A 4-mm-long titanium screw with a diameter of 3.75 mm was inserted in the bone behind the ear, and a bone conduction hearing aid was attached.. The term osseointegration was coined by Professor Brånemark. During animal studies, he found the bone tissue attached to the titanium implant without any soft tissue in between. He also showed an such an implant could take a heavy load. His definition of osseointegration was "direct contact between living bone and an implant that can take a ...
After a brief discussion of the past use of and clinical need for high frequency hearing tests, a new technique is described that uses a special electric transduction mode: a 60-kHz carrier frequency is modulated by the desired audiofrequency. The combined signal is applied to the skin over the mastoids by Mylar-covered electrodes. On perception, the audiofrequency part of the input shows all the properties of a bone-conduction signal. The carrier frequency is dispersed in the tissues. Production and calibration of electrical high frequency signals, up to 20 kHz, is straightforward and easier than that of conventional air-conduction and (vibromechanical) bone-conduction signals. The efficacy of the method is illustrated by means of preliminary hearing tests conducted on several subjects.

Do you have conductive hearing loss? Read Jays story to find out more about it, and how a bone conduction implant like BONEBRIDGE could be the right solution for you.
Auditory evoked potentials (AEP) are highly demanded during the whole process of equipping patients with cochlear implants (CI). They play an essential role in preoperative diagnostics, intraoperative testing, and postoperative monitoring of auditory performance and success. The versatility of AEPs is essentially enhanced by their property to be evokable by acoustic as well as electric stimuli. Thus, the electric responses of the auditory system following acoustic stimulation and recorded by the conventional surface technique as well as by transtympanic derivation from the promontory (Electrocochleography [ECochG]) are used for the quantitative determination of hearing loss and, additionally, electrically evoked compound actions potentials (ECAP) can be recorded with the intracochlear electrodes of the implant just adjacent to the stimulation electrode to check the functional integrity of the device and its coupling to the auditory system ...
For those people affected by deafness in one ear life without stereo hearing can beyond frustrating. The embarrassment of having to repeatedly ask the person to your right, or left if that is your affected side, to repeat themselves seams unending. Then there is the fear of turning over in your sleep and not being able to hear your child crying, the phone ringing, alarm clock going off, or heaven forbid the smoke alarm sounding, is not only an inconvenience, it can be down right deadly.. So for those people afflicted by such a handicap, Sonitus Medical has a new hearing aid device that uses the teeth and bone in the mouth and jaw to help transmit sound to the inner ear when the outer ear is injured. Consisting of two separate parts, the user of the SoundBite Hearing Aid System slips a behind-the-ear (BTE) device onto their ear. The BTE picks up sounds and then transmits a signal to a small unit worn in-the-mouth (ITM). The ITM then transmits the sound to the inner ear via bone conduction. The ...
Cochlear calls for action to avoid proposed Medicare rule If the Centers for Medicare and Medicaid Solutions adopts a fresh rule proposed in July, people with certain types of hearing loss wont be able to secure Medicare coverage for several types of hearing prosthetics which have been covered since 2006. The adoption of the guideline could affect the quality of hearing for thousands of people in the usa who cannot use traditional hearing aids because of chronic or congenital problems, such as atresia and microtia, or who have tried traditional hearing aids and discovered them to become ineffective. As opposed to traditional hearing helps, which arent covered less than Medicare, osseointegrated hearing implants are surgically implanted and make use of bone conduction to replace the function of the center hearing or the cochlea, whereas hearing helps need no surgical intervention and are not permanent.. ...

A The wave function implies that electron 1 is resident in orbital u and electron 2 is in orbital b and that electrons can so be distinguished. This is not possible. e. it does not change sign if the two electrons are exchanged between their occupancies of the two orbitals. The orbital part of w,, does change sign if the two electrons are exchanged, and is anti-symmetric to that operation. If the two electrons possess identical spins, the two spin wave functions can be written as: a( l)a(2)and p( 1)p(2), a and p being used to represent the two possible values of the electron spin. The breakdown of orbital degeneracy (for a given I value) in a magnetic field explains the Zeeman effect.

OBJECTIVE To determine whether adult cochlear implant (CI) users with superior canal dehiscence syndrome (SCDS) or asymptomatic superior semicircular canal dehiscence (SCD) have different surgical, vestibular, and audiologic outcomes when compared to CI users with normal temporal bone anatomy. METHODS A retrospective single institution review of CI users with either superior semicircular canal dehiscence syndrome or asymptomatic superior semicircular canal dehiscence identified eight post-lingually deafened adults with unilateral or bilateral cochlear implantation between 2006 and 2010. Preoperative and postoperative speech perception scores as well as medical and epidemiological data were recorded and analyzed. RESULTS One patient with superior canal dehiscence syndrome and seven patients with asymptomatic superior semicircular canal dehiscence were identified, representing 7% or 8/113 of CI patients that fulfilled selection criteria. Average dehiscence length was 3.3 mm ± 0.79 SEM. Three patients

Superior semicircular canal dehiscence (SCD) is a condition in which the bone overlying the superior semicircular canal is absent. The clinical presentation of SCD is highly variable and may include both auditory and vestibular manifestations. The more common symptoms include autophony, sound or pressure induced vertigo, hypersensitivity to sound, and low frequency conductive hearing loss. Repair can be accomplished via either transmastoid or middle fossa approaches, with numerous materials used to either plug or resurface the canal. Herein, we describe our resurfacing technique using a loose areolar tissue-bone pâté-loose areolar tissue sandwich through a middle fossa approach. DOI#: http://dx.doi.org/10.17797/kcwvab3b7r
Recently Minor and co-workers described patients with sound- and pressure-induced vertigo due to dehiscence of bone overlying the superior semicircular canal. Identifying patients with this "new" vestibular entity is important, not only because the symptoms can be very incapacitating, but also because they are surgically treatable. We present symptoms and findings for three such patients. On exposure to sounds, especially in the frequency range 0.5-1 kHz, they showed vertical/torsional eye movements analogous to a stimulation of the superior semicircular canal. They also showed abnormally large sound-induced vestibular-evoked myogenic potentials (VEMP), i.e. the short latency sternomastoid muscle response considered to be of saccular origin. The VEMP also had a low threshold, especially in the frequency range 0.5-1 kHz. However, in response to saccular stimulation by skull taps, i.e. when the middle ear route was bypassed, the VEMP were not enlarged. This suggests that the relation between the ...

Hearing aids have quite a long and interesting history and have gone through different stages, designs, concepts and technologies. However, their basic function to help those people with hearing loss has not changed but rather has evolved attempting to encompass as many cases as possible and to cover a wider range of hearing impairment severity. The first mention of a hearing aid or similar device dates back to the 16th century. In the next two centuries the hard of hearing mainly used hearing aid trumpets to amplify sounds. These were made from seashells, glass, animal horns and later on from copper and brass. In the 18th century, the technology of bone conduction was implemented through fan-shaped aids, which were positioned behind the ear and transmitted sound vibrations through the bones of the skull to the brain. With time, however, people became more self-conscious and felt the need to hide their disability. That led to hiding or masking the hearing devices in clothes, special hairstyles or
According top Hunds rule I have a [tex]^{3}P[/tex] term which should be the term for the ground state for a [tex]2p^{2}[/tex] shell (in this case the outer sub-shell), this means that I have a triplet state and thus a symmetric wave function for the spinn. Since the electrons are femions the total wave function should be anti-symmetric, this means that my spartial wave functions must be anti-symmetric ...
Identification of conductive hearing loss is a fundamental component of hearing assessment, yet situational and/or equipment constraints can render use of the traditional audiological test suite impractical or impossible. A combination of automatically administered pure-tone audiometry and a tone-in-noise detection task, both delivered via an air-conduction pathway, predicted the presence of an air-bone gap with a reasonably high degree of accuracy in 120 ears with a variety of hearing loss types. The prediction became more accurate with increasing air-bone gap size, with decreasing test frequency, and when multiple test frequencies were taken into account ...

  • With normal inner anatomy, sound conducted by the skull bone improves hearing. (wikipedia.org)
  • The sound quality is also impaired as much of the sound energy is lost in the soft tissue over the skull bone, particularly for the higher sound frequencies important for speech understanding in noise. (wikipedia.org)
  • ZEROi has four compact bone conduction speakers hidden inside of the body of the hat to prevent noise leakage from the speakers. (tennesseeheadlines.com)
  • Cardiac defects include ventral and atrial septation and problems with the conduction system. (wikipedia.org)
  • BMP (Bone morphogenetic protein) cell signaling plays a key role in diverse aspects of cardiac differentiation and morphogenesis. (wikipedia.org)
  • The cardiac conduction system (and AV node part of it) coordinates myocyte mechanical activity. (wikipedia.org)
  • Holt-Oram syndrome (also called Heart and Hand Syndrome, atrio-digital syndrome, atriodigital dysplasia, cardiac-limb syndrome, heart-hand syndrome type 1, HOS, ventriculo-radial syndrome) is an autosomal dominant disorder that affects bones in the arms and hands (the upper limbs) and may also cause heart problems. (wikipedia.org)
  • Cardiac conduction disease can lead to problems such as a slow heart rate (bradycardia) or a rapid and ineffective contraction of the heart muscles (fibrillation). (wikipedia.org)
  • Cardiac conduction disease can occur along with other heart defects (such as septal defects) or as the only heart problem in people with Holt-Oram syndrome. (wikipedia.org)
  • This is because the ear with the conductive hearing loss is only receiving input from the bone conduction and no air conduction, and the sound is perceived as louder in that ear. (wikipedia.org)
  • The atrioventricular node, or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart. (wikipedia.org)
  • Bone conduction is new to the phones itself but there are headsets that already feature this . (blogspot.com)
