Audiometers are devices employed to evaluate the level of hearing and to quantify and diagnose the degree of hearing loss. Audiometers consist of embedded hardware and a test subject feedback button connected to a pair of headphones. This system is controlled by a standard PC. The method of testing the hearing capacity is known as audiometry. Types of audiometry procedures include pure tone audiometry, immittance audiometry, speech audiometry, and evoked response audiometry. Pure tone audiometry is a process in which a patient is made to hear pure tones such as high-pitched tones at frequent intervals to determine the level of hearing loss. Speech audiometry is similar to pure tone audiometry, in terms of process followed; however, pure tones are replaced by human speech to determine the extent and area of hearing loss. Immittance audiometry is a process in which resistance offered by the ear parts to incoming sound is measured.. The global audiometers market is projected to witness modest ...

Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems.
Hearing screening should be conducted in a clinical or natural environment that is conducive to obtaining reliable screening results and that is free from auditory and visual distractions and interruptions. In addition, the location should allow for privacy and confidentiality.. Perform daily listening checks to rule out defects in major pure-tone screening components. Ambient noise levels may exceed ANSI standards for pure-tone threshold testing in audiometric test rooms (ANSI, 2013) but must be sufficiently low to allow accurate screening. A sound level meter, if available, may be used to establish maximum permissible noise levels at 25 dB HL for the earphone to be used during screening (i.e., supra-aural or insert earphones). However, when a sound level meter is not available, a biologic check is suitable.. ...

Objective. Deferoxamine therapy in lifelong transfusion-dependent anaemias, as beta-thalassemia major, is associated with an increased risk of ototoxic changes. With increasing survival rates, prevention and/or early detection of ototoxicity are important for providing management options. The predictive value of pure-tone audiometry in early detection of ototoxicity has been questioned, particularly in the higher frequencies. Otoacoustic emissions appear to be more sensitive to cochlear insult than the conventional pure-tone audiometry. The aim of our study was to compare the efficacy of otoacoustic emissions (distortion-product otoacoustic emissions) with that of pure-tone audiometry as method of audiological monitoring ...
Introduction: Hearing loss is fairly a common disorder which is usually treated with corticosteroids via systemic administration and/or intra-tympanic injection. This study aimed to compare the effectiveness of intra-tympanic injections of dexamethasone with its combination with hyaluronic acid in patients with sudden sensorineural hearing loss. Materials and Methods: In this clinical trial, 40 patients were randomly assigned to two groups; in the first group, 20 patients received 2.4 mg intra-tympanic dexamethasone, while in the second group patients received injections of 2.4 mg of dexamethasone plus 2 mg of hyaluronic acid in combination. Patients in both groups were injected every other day to a total of three injections. The hearing status of patients was evaluated by pure tone audiometry (bone conduction threshold) before and 2 weeks after the intervention. Results: Assessment of hearing threshold before and after treatment in the two groups showed a significant difference between hearing
GUIDA, Heraldo Lorena; SOUSA, Ariane Laís de and CARDOSO, Ana Cláudia Vieira. Relationship between the findings of pure-tone audiometry and otoacoustic emission tests on military police personnel. Arquivos Int. Otorrinolaringol. [online]. 2012, vol.16, n.1, pp.67-73. ISSN 1809-4856. http://dx.doi.org/10.7162/S1809-48722012000100010.. INTRODUCTION: Otoacoustic emissions can be an alternative for cochlear evaluation in noise induced hearing loss (NIHL). OBJECTIVE: To investigate the correlation between the findings of audiometry results and distortion product otoacoustic emissions (DPOAE) in the military police. METHOD: from cross-sectional and retrospective study, 200 military police officers were submitted to audiological evaluation - pure tone audiometry and DPOAE. RESULTS: considering the provisions of Ordinance 19 of the Labour Department, the results were suggestive of induced hearing loss by high sound pressure levels in 58 individuals, distributed as follows: 28 (48.3%) bilateral cases ...
Audiologists regularly encounter the following scenario: A patient comes into the clinic with complaints of difficulty hearing speech in background noise. An adult patient is often accompanied by a family member, perhaps a spouse or an older child, who readily confirms his or her loved ones communication problems. Concerns about difficulties with speech perception in noise are often raised by parents of school-age children. The childs school teacher and maybe primary care physician share the concerns. Then, the patients pure tone audiometry reveals hearing thresholds within normal limits. Or, especially for the elderly, the audiogram documents a modest deficit in hearing thresholds that is not compatible with the patients complaints.. Based solely on the results of pure tone audiometry and probably a few simple speech recognition tests, the audiologist may confidently tell the patient and indicate in a formal report that "our testing shows that you have normal hearing." However, in most ...
According to The National Institute for Occupational Safety and Health (NIOSH), occupational hearing loss is one of the most common work-related illnesses in the United States. Approximately 22 million U.S. workers are exposed to hazardous noise levels at work, and an additional 9 million are exposed to chemicals that can damage hearing or balance functions of the ear. An estimated $242 million is spent annually in the U.S. on worker s compensation for hearing loss disability., , , , Occupati...

OBJECTIVE: There are only a few population-based epidemiological studies on audiogram configurations among adults. The aim of this study was to investigate the prevalence of different audiogram configurations among older adults. In addition, audiogram configurations among subjects reporting hearing problems were examined.. DESIGN: Cross-sectional, population-based, unscreened epidemiological study among older adults.. STUDY SAMPLE: The subjects (n = 850), aged 54-66 years, were randomly sampled from the population register. A questionnaire survey, an otological examination, and pure-tone audiometry were performed.. RESULTS: The most prevalent audiogram configuration among men was high-frequency steeply sloping (65.3% left ear, 51.2% right ear) and among women, high-frequency gently sloping (33.0% left ear, 31.5% right ear). There were significantly more flat configurations among women than among men. Unclassified audiograms were common especially among women (17.5%). Subjects reporting hearing ...

Audiometry or the hearing test helps to determine the ability of a person to hear various sounds and consequently identify the location of damage in a person with diminished hearing sensitivity.
The impacts of the Sask. Partys recent budgets are still hurting families throughout the province in many ways. For instance, many are now struggling with the consequences of the Sask. Party cut to the Hearing Aid Plan - a service that provided audiological evaluation, hearing aids and fittings, counselling and education.. "After years of blowing through record revenues, the Sask. Party panicked when the money ran out and started cutting in areas that would hurt the most vulnerable," said NDP Health Critic Vicki Mowat. "For over 40 years, this was a program that helped so many people and families throughout the province. It hasnt taken long to see the damage that cutting it has done.". Stephanie Schneck and her 9-year-old daughter Gracie are among the many who have borne the brunt of these Sask. Party cuts. Gracie needs $6,400 hearing aids, but her parents cant afford to pay for them and have been forced to hold fundraisers to provide her with the health services she needs. Stephanie is ...
Tinnitus belongs to the most important symptoms in neurootology besides of vertigo, nausea and hearing loss. In most of the cases still the origin of the tinnitus is not yet explainable. It is well known that tinnitus may arise in any part of the hearing pathways, i.e., the cochlea receptor as well the temporal lobe and projection.. Frequently tinnitus is combined with the above mentioned neurootological symptoms vertigo, nausea and hearing loss. Especially in patients growing over the age of 40, the sign of tinnitus is increasingly found. However, we have to discriminate between an endogenous and maskable tinnitus from and exogenous tinnitus, which is produced by distorted hearing pathway actions under the picture of the hypersensitive ear.. In the history already the patients suffering from exogenous tinnitus explain, that they must avoid external noise. Of course a thorough analysis of the hearing pathways is performed in the neurootological laboratory including speech audiometry, otoacoustic ...
An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain. Sound waves can travel to the inner ear through the ear canal,...
This study is based on an analysis of 14 patients with VS treated with stereotactic radiosurgery or radiotherapy in a newly setup cancer center in 2014 using a LINAC-based radiotherapy machine. Patients selection was done by a team of clinical oncologists, neurosurgeons and radiologists during tumour board meetings. All patients underwent pure tone audiometry, MR imaging and CT simulation planning sessions where these images were fused and treatment planning were done. A customised immobilisation device was fabricated during the CT simulation planning session using a frameless stereotactic mask system. 57% (n = 8) had SRS (12 Gy in single fraction) and 43% had hypofractionated SRT (35Gy in 7 fractions) as primary treatment. During treatment verification, image guidance consisting of dual in-room kV x-ray, two infrared cameras and 6D robotic couch patients positioning were used. The patients were then seen in clinic at six weeks post treatment to assess early side effects following which 6 ...

A total of 90 imaging studies were reviewed (ESD = 22; non-ESD = 30; control = 38). ESD and non-ESD groups had similar pure-tone averages (33.9 ± 20.6 versus 41.6 ± 22.6 dB HL; p = 0.21) and frequency of definite Menières disease (59.1% versus 53.3%; p = 0.68). There was no significant trend between groups for any measurement. One nonsignificant trend existed in mean vestibule length, increasing from the control (5.45 ± 0.54 mm), non-ESD (5.80 ± 0.97 mm), and ESD (5.94 ± 0.81 mm) group. In a combined Menières group, mean vestibule length was significantly greater than controls (5.86 ± 0.89 versus 5.45 ± 0.54 mm; p = 0.008) and mean vestibule width significantly less (2.99 ± 0.46 versus 3.19 ± 0.39 mm; p = 0.024 ...

TY - JOUR. T1 - Case of recurrent, reversible, sudden sensorineural hearing loss in a child.. AU - Gorga, Michael P. AU - Stelmachowicz, P. G.. AU - Barlow, Steven M. AU - Brookhouser, P. E.. PY - 1995/3/1. Y1 - 1995/3/1. N2 - This paper describes audiologic, electrophysiologic, and medical test results for a now 10-year-old girl who has had 45 episodes of reversible, sudden sensorineural hearing loss over the last 8 years. Episodes have lasted from 6 to 72 hours and often have been accompanied by a mild illness. Acoustic immittance measures have been consistent with normal middle-ear function with the exception of absent ipsilateral and contralateral acoustic reflexes. Mechanically evoked perioral reflex activity was markedly asymmetric following lower lip stimulation. The asymmetry of R1 activation between right and left side lower lip inputs raises questions about the integrity of central connections within the brain stem, including internuncial pathways coursing between trigeminal sensory ...
OBJECTIVE: The immunosuppressive agent cyclosporin A (CsA) has contributed to the success of organ and bone marrow transplantation. CsA-related neurotoxicity is a well-known occurrence. Sensorineural hearing loss (SNHL) due to initiation of CsA treatment is an extremely rare finding. MATERIAL AND METHODS: A 32-year-old man who had undergone technically uneventful cadaveric renal transplantation for focal glomerulosclerosis when 25 years old was evaluated as the result of a 10-month history of bilateral hearing loss. The patient had been taking only CsA (150 mg twice daily) and methylprednisolone. RESULTS: Progressive bilateral SNHL was confirmed by an audiological examination. Eight months after dose reduction of CsA, pure-tone audiometry excluded progression of hearing loss. CONCLUSIONS: To the best of our knowledge, only rare cases of CsA-related hearing loss have been reported, and none after long-term CsA treatment. Audiological findings confirmed the cochlear origin of SNHL in our patient. ...

The biological calibration was performed through the pediatric audiometer (Interacoustics) to determine the normal hearing threshold, according to each frequency, to be used as a parameter in this research. The measurement of noise levels was performed in non-treated environments in the ICB5 building in Monte Negro to delimitate the scales of environmental noise in which the evaluation might be performed during the visits. The Bruel & Kjaer 2236 Sound Level Meter Type II was used. The values of environmental noise level found ranged from 50 to 66 dB Sound Pressure Level (SPL).. The hearing threshold between 0 and 20 dB hearing level was obtained for frequencies of 1 kHz, 2 kHz and 4 kHz in a normal-hearing child and an adult (controls) in the mentioned environment. These control subjects had previously undergone a conventional audiological evaluation in an acoustic booth, so as to confirm the absence of any hearing alteration. The maximum intensity of 66 dBSPL was established as the standard ...
28) evaluated 29 patients with idiopathic sudden sensorineural hearing loss and 29 controls and showed that the two groups did not differ with regards to cIMT and other cardiovascular risk factors; however, flow-mediated dilation of the brachial artery predisposed individuals to develop idiopathic sudden sensorineural hearing loss (p=0.03, odds ratio: 1.4). There is evidence to suggest that hearing and vestibular function might be influenced by disease activity and autoimmune processes. RA patients may develop autoimmune inner-ear disease due to SNHI. There are some reports indicating that anti-tumor necrosis factor alpha agents (etanercept, adalimumab and infliximab) may offer additional treatment options for patients with autoimmune hearing loss.(20-22) Hearing impairment in RA is a subclinical comorbid state. Since most of the patients are not aware of their HI and have no clinical complaints, it is important that physicians consider hearing damage in these patients.(2,3,14) Despite of the ...
Objectives: Young people are often exposed to high music levels which make them more at risk to develop noise-induced symptoms such as hearing loss, hyperacusis, and tinnitus of which the latter is the symptom perceived the most by young adults. Although, subclinical neural damage was demonstrated in animal experiments, the human correlate remains under debate. Controversy exists on the underlying condition of young adults with normal hearing thresholds and noise-induced tinnitus (NIT) due to leisure noise. The present study aimed to assess differences in audiological characteristics between noise-exposed adolescents with and without NIT.Methods: A group of 87 young adults with a history of recreational noise exposure was investigated by use of the following tests: otoscopy, impedance measurements, pure-tone audiometry including high-frequencies, transient and distortion product otoacoustic emissions, speech-in-noise testing with continuous and modulated noise (amplitude-modulated by 15 Hz), auditory
