Acoustics
The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it. (From Random House Unabridged Dictionary, 2d ed)
Speech Acoustics
The acoustic aspects of speech in terms of frequency, intensity, and time.
Sound Spectrography
The graphic registration of the frequency and intensity of sounds, such as speech, infant crying, and animal vocalizations.
Phonation
The process of producing vocal sounds by means of VOCAL CORDS vibrating in an expiratory blast of air.
Voice Quality
That component of SPEECH which gives the primary distinction to a given speaker's VOICE when pitch and loudness are excluded. It involves both phonatory and resonatory characteristics. Some of the descriptions of voice quality are harshness, breathiness and nasality.
Sound
A type of non-ionizing radiation in which energy is transmitted through solid, liquid, or gas as compression waves. Sound (acoustic or sonic) radiation with frequencies above the audible range is classified as ultrasonic. Sound radiation below the audible range is classified as infrasonic.
Vocal Cords
A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.
Speech Intelligibility
Ability to make speech sounds that are recognizable.
Speech Production Measurement
Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody.
Vocalization, Animal
Sounds used in animal communication.
Psychoacoustics
The science pertaining to the interrelationship of psychologic phenomena and the individual's response to the physical properties of sound.
Noise, Occupational
Noise present in occupational, industrial, and factory situations.
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.
Speech Perception
The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).
Ultrasonics
A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.
Noise
Any sound which is unwanted or interferes with HEARING other sounds.
Acoustic Stimulation
Use of sound to elicit a response in the nervous system.
Cues
Signals for an action; that specific portion of a perceptual field or pattern of stimuli to which a subject has learned to respond.
Time Factors
Elements of limited time intervals, contributing to particular results or situations.
Vanilla
A plant genus of the family ORCHIDACEAE that is the source of the familiar flavoring used in foods and medicines (FLAVORING AGENTS).
Cardioplegic Solutions
Solutions which, upon administration, will temporarily arrest cardiac activity. They are used in the performance of heart surgery.
Paeonia
A plant genus of the family Paeoniaceae, order Dilleniales, subclass Dilleniidae, class Magnoliopsida. These perennial herbs are up to 2 m (6') tall. Leaves are alternate and are divided into three lobes, each lobe being further divided into three smaller lobes.

Viscoelastic properties of f-actin, microtubules, f-actin/alpha-actinin, and f-actin/hexokinase determined in microliter volumes with a novel nondestructive method. (1/1046)

A nondestructive method to determine viscoelastic properties of gels and fluids involves an oscillating glass fiber serving as a sensor for the viscosity of the surrounding fluid. Extremely small displacements (typically 1-100 nm) are caused by the glass rod oscillating at its resonance frequency. These displacements are analyzed using a phase-sensitive acoustic microscope. Alterations of the elastic modulus of a fluid or gel change the propagation speed of a longitudinal acoustic wave. The system allows to study quantities as small as 10 microliters with temporal resolution >1 Hz. For 2-100 microM f-actin gels a final viscosity of 1.3-9.4 mPa s and a final elastic modulus of 2.229-2.254 GPa (corresponding to 1493-1501 m/s sound velocity) have been determined. For 10- to 100-microM microtubule gels (native, without stabilization by taxol), a final viscosity of 1.5-124 mPa s and a final elastic modulus of 2.288-2. 547 GPa (approximately 1513-1596 m/s) have been determined. During polymerization the sound velocity in low-concentration actin solutions increased up to +1.3 m/s (approximately 1.69 kPa) and decreased up to -7 m/s (approximately 49 kPa) at high actin concentrations. On polymerization of tubulin a concentration-dependent decrease of sound velocity was observed, too (+48 to -12 m/s approximately 2.3-0.1 MPa, for 10- to 100-microM tubulin). This decrease was interpreted by a nematic phase transition of the actin filaments and microtubules with increasing concentration. 2 mM ATP (when compared to 0.2 mM ATP) increased polymerization rate, final viscosity and elastic modulus of f-actin (17 microM). The actin-binding glycolytic enzyme hexokinase also accelerated the polymerization rate and final viscosity but elastic modulus (2.26 GPa) was less than for f-actin polymerized in presence of 0.2 mM ATP (2.28 GPa).  (+info)

What is distinct about infants' "colic" cries? (2/1046)

AIMS: To investigate (1) whether colic cries are acoustically distinct from pre-feed "hunger" cries; (2) the role of the acoustic properties of these cries versus their other properties in accounting for parents' concerns about colic. DESIGN: From a community sample, infants were selected who met Wessel colic criteria for amounts of crying and whose mothers identified colic bouts. Using acoustic analyses, the most intense segments of nine colic bouts were compared with matched segments from pre-feed cries presumed to reflect hunger. RESULTS: The colic cries did not have a higher pitch or proportion of dysphonation than the pre-feed cries. They did contain more frequent shorter utterances, but these resembled normal cries investigated in other studies. There is no evidence that colic cries have distinct acoustic features that are reproducible across samples and studies, which identify a discrete clinical condition, and which are identified accurately by parents. CONCLUSIONS: The most reliable finding is that colic cries convey diffuse acoustic and audible information that a baby is highly aroused or distressed. Non-acoustic features, including the prolonged, hard to soothe, and unexplained nature of the cries may be specific to colic cries and more important for parents. These properties might reflect temperament-like dispositions.  (+info)

Voice-controlled robotic arm in laparoscopic surgery. (3/1046)

AIM: To report on our experience with a voice-directed robotic arm for scope management in different procedures for "solo-surgery" and in complex laparoscopic operations. METHODS: A chip card with orders for the robotic arm is individually manufactured for every user. A surgeon gives order through a microphone and the optic field is thus under direct command of the surgeon. RESULTS: We analyzed 200 cases of laparoscopic procedures (gallbladder, stomach, colon, and hernia repair) done with the robotic arm. In each procedure the robotic arm worked precisely; voice understanding was exact and functioned flawlessly. A hundred "solo-surgery" operations were performed by a single surgeon. Another 96 complex videoscopic procedures were performed by a surgeon and one assistant. In comparison to other surgical procedures, operative time was not prolonged, and the number of used ports remained unchanged. CONCLUSION: Using the robotic arm in some procedures abolishes the need for assist ance. Further benefit accrued by the use of robotic assistance includes greater stability of view, less inadvertent smearing of the lens, and the absence of fatigue. The robotic arm can be used successfully in every operating theater by all surgeons using laparoscopy.  (+info)

Cochlear function: hearing in the fast lane. (4/1046)

The cochlea amplifies sound over a wide range of frequencies. Outer hair cells have been thought to play a mechanical part in this amplification, but it has been unclear whether they act rapidly enough. Recent work suggests that outer hair cells can indeed work at frequencies that cover the auditory range.  (+info)

Advances in photoacoustic noninvasive glucose testing. (5/1046)

We report here on in vitro and in vivo experiments that are intended to explore the feasibility of photoacoustic spectroscopy as a tool for the noninvasive measurement of blood glucose. The in vivo results from oral glucose tests on eight subjects showed good correlation with clinical measurements but indicated that physiological factors and person-to-person variability are important. In vitro measurements showed that the sensitivity of the glucose measurement is unaffected by the presence of common blood analytes but that there can be substantial shifts in baseline values. The results indicate the need for spectroscopic data to develop algorithms for the detection of glucose in the presence of other analytes.  (+info)

Mosquito hearing: sound-induced antennal vibrations in male and female Aedes aegypti. (6/1046)

Male mosquitoes are attracted by the flight sounds of conspecific females. In males only, the antennal flagellum bears a large number of long hairs and is therefore said to be plumose. As early as 1855, it was proposed that this remarkable antennal anatomy served as a sound-receiving structure. In the present study, the sound-induced vibrations of the antennal flagellum in male and female Aedes aegypti were compared, and the functional significance of the flagellar hairs for audition was examined. In both males and females, the antennae are resonantly tuned mechanical systems that move as simple forced damped harmonic oscillators when acoustically stimulated. The best frequency of the female antenna is around 230 Hz; that of the male is around 380 Hz, which corresponds approximately to the fundamental frequency of female flight sounds. The antennal hairs of males are resonantly tuned to frequencies between approximately 2600 and 3100 Hz and are therefore stiffly coupled to, and move together with, the flagellar shaft when stimulated at biologically relevant frequencies around 380 Hz. Because of this stiff coupling, forces acting on the hairs can be transmitted to the shaft and thus to the auditory sensory organ at the base of the flagellum, a process that is proposed to improve acoustic sensitivity. Indeed, the mechanical sensitivity of the male antenna not only exceeds the sensitivity of the female antenna but also those of all other arthropod movement receivers studied so far.  (+info)

Experience-dependent modification of ultrasound auditory processing in a cricket escape response. (7/1046)

The ultrasound acoustic startle response (ASR) of crickets (Teleogryllus oceanicus) is a defense against echolocating bats. The ASR to a test pulse can be habituated by a train of ultrasound prepulses. We found that this conditioning paradigm modified both the gain and the lateral direction of the startle response. Habituation reduced the slope of the intensity/response relationship but did not alter stimulus threshold, so habituation extended the dynamic range of the ASR to higher stimulus intensities. Prepulses from the side (90 degrees or 270 degrees azimuth) had a priming effect upon the lateral direction of the ASR, increasing the likelihood that test pulses from the front (between -22 degrees and +22 degrees ) would evoke responses towards the same side as prepulse-induced responses. The plasticity revealed by these experiments could alter the efficacy of the ASR as an escape response and might indicate experience-dependent modification of auditory perception. We also examined stimulus control of habituation by prepulse intensity or direction. Only suprathreshold prepulses induced habituation. Prepulses from one side habituated the responses to test pulses from either the ipsilateral or contralateral side, but habituation was strongest for the prepulse-ipsilateral side. We suggest that habituation of the ASR occurs in the brain, after the point in the pathway where the threshold is mediated, and that directional priming results from a second process of plasticity distinct from that underlying habituation. These inferences bring us a step closer to identifying the neural substrates of plasticity in the ASR pathway.  (+info)

Vocal tract length and acoustics of vocalization in the domestic dog (Canis familiaris). (8/1046)

The physical nature of the vocal tract results in the production of formants during vocalisation. In some animals (including humans), receivers can derive information (such as body size) about sender characteristics on the basis of formant characteristics. Domestication and selective breeding have resulted in a high variability in head size and shape in the dog (Canis familiaris), suggesting that there might be large differences in the vocal tract length, which could cause formant behaviour to affect interbreed communication. Lateral radiographs were made of dogs from several breeds ranging in size from a Yorkshire terrier (2.5 kg) to a German shepherd (50 kg) and were used to measure vocal tract length. In addition, we recorded an acoustic signal (growling) from some dogs. Significant correlations were found between vocal tract length, body mass and formant dispersion, suggesting that formant dispersion can deliver information about the body size of the vocalizer. Because of the low correlation between vocal tract length and the first formant, we predict a non-uniform vocal tract shape.  (+info)

Since the amount of reflected sound is increased by fluid in the middle ear, it seemed likely that the acoustic otoscope could be used for detection of otitis media. We compared acoustic reflectometry with over 4,000 tympanometric and otoscopic examinations in 451 children who were examined at regular intervals following surgery for chronic otitis media with effusion.

The current study demonstrates that MCA, determined by acoustic pharyngometry, can significantly differentiate between those with mild/no-OSA versus moderate-to-severe OSA. When analyzed alongside other variables such as gender, age, and neck circumference, acoustic pharyngometry was the only independent predictor of detecting the absence of moderate-to-severe OSA. This easily obtained measurement thus has potential utility as a component in a diagnostic algorithm for OSA. With healthcare reform, sleep testing may become less readily available, making decisions to prioritize testing in certain patients important.. Acoustic pharyngometry may also be a useful objective tool in occupational health clinics. The population in certain environments may minimize subjective symptoms in sleep questionnaires, leading to the need for simple and cost-effective tools for objective assessments. In conjunction with basic anthropometric characteristics, pharyngometry can help objectively determine those at high ...

Sensors | Free Full-Text | A Novel Acoustic Sensor Approach to Classify Seeds Based on Sound Absorption SpectraSensors | Free Full-Text | A Novel Acoustic Sensor Approach to Classify Seeds Based on Sound Absorption Spectra
A non-destructive and novel in situ acoustic sensor approach based on the sound absorption spectra was developed for identifying and classifying different seed types. The absorption coefficient spectra were determined by using the impedance tube measurement method. Subsequently, a multivariate statistical analysis, i.e., principal component analysis (PCA), was performed as a way to generate a classification of the seeds based on the soft independent modelling of class analogy (SIMCA) method. The results show that the sound absorption coefficient spectra of different seed types present characteristic patterns which are highly dependent on seed size and shape. In general, seed particle size and sphericity were inversely related with the absorption coefficient. PCA presented reliable grouping capabilities within the diverse seed types, since the 95% of the total spectral variance was described by the first two principal components. Furthermore, the SIMCA classification model based on the absorption spectra

Purpose: To measure the acoustic signal generated by a pulsed proton spill from a hospital-based clinical cyclotron. Methods: An electronic function generator modulated the IBA C230 isochronous cyclotron to create a pulsed proton beam. The acoustic emissions generated by the proton beam were measured in water using a hydrophone. The acoustic measurements were repeated with increasing proton current and increasing distance between detector and beam. Results: The cyclotron generated proton spills with rise times of 18 μs and a maximum measured instantaneous proton current of 790 nA. Acoustic emissions generated by the proton energy deposition were measured to be on the order of mPa. The origin of the acoustic wave was identified as the proton beam based on the correlation between acoustic emission arrival time and distance between the hydrophone and proton beam. The acoustic frequency spectrum peaked at 10 kHz, and the acoustic pressure amplitude increased monotonically with increasing proton ...

Researchers develop new acoustic sensor for chemical and biological detection - Science and Technology Research NewsResearchers develop new acoustic sensor for chemical and biological detection - Science and Technology Research News
Testing for ovarian cancer or the presence of a particular chemical could be almost as simple as distinguishing an F sharp from a B flat, thanks to a new microscopic acoustic device that has been dramatically improved by scientists at the U.S. Department of Energys (DOE) Argonne National Laboratory.. The device, known as a surface acoustic wave (SAW) sensor, detects frequency changes in waves that propagate through its crystalline structure. This makes it ideal for detecting the presence of chemicals or biomarkers present in a liquid or gas. For example, it can detect cancer proteins attached to a receptor on the sensor surface.. The initial wave is created by a physical phenomenon known as the piezoelectric effect, in which an initial electric signal is converted into a mechanical displacement. This displacement takes the form of a wave transmitted through the crystal.. In the SAW sensor, the signal travels like a seismic wave from the input transducer through the material to an output ...

An invisible acoustic sensor based on parity-time symmetryAn invisible acoustic sensor based on parity-time symmetry
Sensing an incoming signal is typically associated with absorbing a portion of its energy, inherently perturbing the measurement and creating reflections and shadows. Here, in contrast, we demonstrate a non-invasive, shadow-free, invisible sensor for airborne sound waves at audible frequencies, which fully absorbs the impinging signal, without at the same time perturbing its own measurement or creating a shadow. This unique sensing device is based on the unusual scattering properties of a parity-time (PT) symmetric metamaterial device formed by a pair of electro-acoustic resonators loaded with suitably tailored non-Foster electrical circuits, constituting the acoustic equivalent of a coherent perfect absorber coupled to a coherent laser. Beyond the specific application to non-invasive sensing, our work broadly demonstrates the unique relevance of PT-symmetric metamaterials for acoustics, loss compensation and extraordinary wave manipulation.. ...

Gear tooth root fatigue test monitoring with continuous acoustic emission: advanced signal processing techniques for detection...Gear tooth root fatigue test monitoring with continuous acoustic emission: advanced signal processing techniques for detection...
The phenomenon of fatigue in gears at the tooth root can be a cause of catastrophic failure if not detected in time. Where traditional low-frequency vibration may help in detecting a well-developed crack or a completely failed tooth, a system for early detection of the nucleation and initial propagation of a fatigue crack can be of great use in condition monitoring. Acoustic emission is a potentially suitable technique, as it is sensitive to the higher frequencies generated by crack propagation and is not affected by low-frequency noise. In this article, a static gear pair is tested where a crack was initiated at a tooth root. Continuous acoustic emission was periodically recorded throughout the test. Data were processed in multiple ways to support the early detection of crack initiation. Initially, traditional feature-based acoustic emission was employed. This showed qualitative results indicating fracture initiation around 8000 cycles. A rolling cross-correlation was then employed to compare ...

Monitoring and mitigating bioacoustic impacts from seismic surveys: The Australian PerspectiveMonitoring and mitigating bioacoustic impacts from seismic surveys: The Australian Perspective
In Australia, proponents of seismic surveys and other operations emitting underwater noise have to prepare an Environmental Plan (EP) for approval by the regulator before operations can commence. In support of the EP, large amounts of data are often collected, such as baseline data on the marine soundscape, the physical and biological environment, operational noise characteristics etc. More data (on underwater noise, animal abundance and behaviour etc.) is sometimes collected during operations as part of monitoring and mitigation plans. Australias offshore oil & gas industry has recently come together to share data from bioacoustic environmental impact assessments, yielding charts of baseline soundscape characteristics, catalogues of anthropogenic source characteristics, improved models for sound field prediction, and growing databases of animal behaviour, abundance and migration. This data sharing will ultimately help to streamline the environmental approval process.. ...

Vocal production in nonhuman primates: Acoustics, physiology, and functional constraints on honest advertisement - Fitch -...Vocal production in nonhuman primates: Acoustics, physiology, and functional constraints on honest advertisement - Fitch -...
The physiological mechanisms and acoustic principles underlying sound production in primates are important for analyzing and synthesizing primate vocalizations, for determining the range of calls that are physically producible, and for understanding primate communication in the broader comparative context of what is known about communication in other vertebrates. In this paper we discuss what is known about vocal production in nonhuman primates, relying heavily on models from speech and musical acoustics. We first describe the role of the lungs and larynx in generating the sound source, and then discuss the effects of the supralaryngeal vocal tract in modifying this source. We conclude that more research is needed to resolve several important questions about the acoustics of primate calls, including the nature of the vocal tracts contribution to call production. Nonetheless, enough is known to explore the implications of call acoustics for the evolution of primate communication. In particular, ...

Fatigue Design Model Based on Damage Mechanisms Revealed by Acoustic Emission Measurements | Journal of Engineering Materials...Fatigue Design Model Based on Damage Mechanisms Revealed by Acoustic Emission Measurements | Journal of Engineering Materials...
Integration of the microcomputer into acoustic emission instrumentation has brought AE monitoring of fatigue tests into the realm of practicality. On-line processing makes available a selection of software tools, enhancing classical techniques for eliminating the background noise which usually blanked out the desired data. Fatigue tests monitored for acoustic emission were carried out at room temperature on Incoloy 901 material specimens, over a stress-ratio range of −1 ≤ R ≤ .2. Valid AE data were obtained even when the load cycle passed through zero. The AE data permitted specific identification of the various phenomena occurring on the way to final failure. These included initial plasticity, crack nucleation and propagation phases. The AE findings were supported by microscopic examination. Based on the experimental data, a preliminary damage-prediction model was formulated.. ...

Woven and unidirectional layups were subjected to the double cantilever beam, end notch flexure, and mixed-mode bending tests and the generated AE signals were captured. Discrimination of the AE events, caused by different types of the damage mechanisms, was performed using wavelet packet transform (WPT) and fuzzy clustering method (FCM) associated with a principal component analysis (PCA). The FCM and WPT analyses identified three dominant damage mechanisms. Furthermore, different interface layups and different GII/GT modal ratio values (ratio of mode II strain energy ...

OSA | Photoacoustic detection of metastatic melanoma cells in the human circulatory systemOSA | Photoacoustic detection of metastatic melanoma cells in the human circulatory system
Detection of disseminating tumor cells among patients suffering from various types and stages of cancer can function as an early warning system, alerting the physician of the metastatic spread or recurrence of the disease. Early detection of such cells can result in preventative treatment of the disease, while late stage detection can serve as an indicator of the effectiveness of chemotherapeutics. The prognostic value of exposing disseminating tumor cells poses an urgent need for an efficient, accurate screening method for metastatic cells. We propose a system for the detection of metastatic circulating tumor cells based on the thermoelastic properties of melanoma. The method employs photoacoustic excitation coupled with a detection system capable of determining the presence of disseminating cells within the circulatory system in vitro. Detection trials consisting of tissue phantoms and a human melanoma cell line resulted in a detection threshold of the order of ten individual cells, thus ...

This paper demonstrates an acoustic sensor that can resolve atomic force microscopy (AFM) tip blunting with a frequency sensitivity of 0.007%. The AFM tip is fabricated on a thin film piezoelectric aluminum nitride (AlN) membrane that is excited as a film bulk acoustic resonator (FBAR). We demonstrate that cutting 0.98 μm off of the tip apex results in a resonance frequency change of 0.4MHz at 6.387GHz. This work demonstrates the potential for in-situ monitoring of AFM tip wear.

Urinary bladder fibrosis (thickening and scarring) is fairly uncommon in children. Traditionally, the presence of urinary bladder fibrosis has been confirmed directly with bladder biopsy or using urodynamic testing.. We will use ultrasound ARFI (acoustic radiation force impulse)-derived shear wave velocities to potentially identify the presence of urinary bladder wall fibrosis. We hypothesize that shear wave velocities found within the bladder wall will increase with increasing evidence of fibrosis. ...

Acoustic Radiation Force Impulse (ARFI) and Transient Elastography (TE) for evaluation of liver fibrosis in HIV-HCV co-infected...
BACKGROUND: Transient elastography (TE) is widely used for non-invasive assessment of liver fibrosis in HIV-HCV co-infected patients. TE, however, cannot determine liver morphology. Acoustic radiation force impulse (ARFI) imaging is a novel procedure enabling assessment of liver fibrosis during a conventional ultrasonographic examination. This study evaluated the correlation between liver fibrosis measurements by TE and ARFI. METHODS: Each of 46 HIV-HCV patients underwent both ARFI and TE within 6 months. Patients were evaluated by the equivalent METAVIR scoring system, using previously established cut-off values. Agreements between the ARFI and TE scores were estimated by Kappa coefficients, with Kappa values ≥0.40, ≥0.60, and ≥0.80 defined as moderate, good and very good agreement, respectively. RESULTS: ARFI and TE yielded Equivalent Metavir fibrosis scores of F1 in 26 and 31 patients, respectively; F2 in nine and seven, respectively; F3 in three and two, respectively; and F4 in eight and

A method for reliable, noninvasive estimation of Abdominal Aortic Aneurysms (AAA) wall mechanics may be a useful clinical tool for rupture prediction. An in vitro AAA model was developed from an excised porcine aorta, with elastase treatment. The AAA model behaviour was analysed using Acoustic Radiation Force Impulse (ARFI) imaging techniques to generate displacements in both aneurysmal and normal aortic tissue. The incremental modulus of the arteries was indicative of early collagen recruitment, typical in aneurysms due to elastin degradation. Opening angle measurement showed a four fold decrease from healthy aorta to AAA model. The mechanical changes that occur during aneurysm formation were found to be detectable using ARFI imaging ...

Emotional Impact of Music Influenced by Acoustics of Concert Halls - Neuroscience NewsEmotional Impact of Music Influenced by Acoustics of Concert Halls - Neuroscience News
Concert halls with strong and lateral sound increase the emotional impact of orchestra music. An audiences auditory experience during a thrilling and emotive live symphony concert is an intertwined combination of the music and the acoustic response of the concert hall. Music in itself is known to elicit emotional pleasure, and at best, listening to music may evoke concrete psychophysiological responses. Certain concert halls have gained a reputation for superior acoustics, but despite the continuous research by a multitude of objective and subjective studies on room acoustics, the fundamental reason for the appreciation of some concert halls remains elusive. This study demonstrates that room acousticeffects contribute to the overall emotional experience of a musical performance. In two listening tests, the subjects listen to identical orchestra performances rendered in the acoustics of several concert halls. The emotional excitation during listening is measured in the first experiment, and in ...

Underwater acoustics - WikipediaUnderwater acoustics - Wikipedia
Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water and its boundaries. The water may be in the ocean, a lake or a tank. Typical frequencies associated with underwater acoustics are between 10 Hz and 1 MHz. The propagation of sound in the ocean at frequencies lower than 10 Hz is usually not possible without penetrating deep into the seabed, whereas frequencies above 1 MHz are rarely used because they are absorbed very quickly. Underwater acoustics is sometimes known as hydroacoustics. The field of underwater acoustics is closely related to a number of other fields of acoustic study, including sonar, transduction, acoustic signal processing, acoustical oceanography, bioacoustics, and physical acoustics. Underwater sound has probably been used by marine animals for millions of years. The science of underwater acoustics began in 1490, when Leonardo da Vinci wrote the following, If you cause your ...

Composite Acoustics acoustic guitars, bass guitarsComposite Acoustics acoustic guitars, bass guitars
Composite Acoustics (CA) guitars grew from an idea by a former aerospace engineer and guitar aficionado to make acoustic guitars using composites instead of wood. Having developed composite materials that could reproduce the sound characteristics of the wood instruments, C.A.s initial pursuit as a company was to offer their proprietary technology to existing guitar manufacturers who had the capacity to build the next generation of acoustic instruments. Despite the recognition that great tone woods are becoming alarmingly scarce CA found that existing manufacturers were slow to adopt new materials due in part to their existing investment in wood stocks and related wood working equipment. At this point CA determined to build composite guitars themselves, introducing a series of carbon fiber acoustic guitars in the early 2000s.. By early 2010, however, CA had ceased production. Peavey Electronics Corporation purchased CA in late 2010 and re-launched the brand in 2011. Composite Acoustics are proud ...

SCIplanet - Architectural AcousticsSCIplanet - Architectural Acoustics
Architecture and interior design both affect and are affected by a diversity of factors that one might not give much thought to, despite being very much influenced by them. Light, materials, and colors are among, if not the only obvious factors that immediately come to mind; a highly significant factor that does not, yet has tremendous effect on the functionality of any building, is acoustics.. Having had the opportunity to travel quite a bit over the past couple of decades, I have had a diversity of experiences with hotel rooms, as well as entertainment theaters. In both cases, the role of acoustics has been quite evident to me. In the first, more personal experience, I noticed that the higher the level of the accommodation I experienced, the quieter my room was, and vice versa. The quieter my room was, the better isolated I felt from my surroundings, and the safer I felt, and vice versa. In the second case, however, the best, most entertaining experiences involved feeling completely immersed ...

Effect of Acoustic Radiation Force on the Cornea in vivo | IOVS | ARVO JournalsEffect of Acoustic Radiation Force on the Cornea in vivo | IOVS | ARVO Journals
Purpose: : The application of force to the cornea has long been used for measurement of intraocular pressure and more recently to probe the elastic properties of the cornea itself. Current modalities exert force onto the anterior surface of the cornea. Our aim was to ascertain if acoustic radiation force, which would be absorbed across the full corneal thickness, could be safely used to generate corneal surface displacements. Methods: : We tested two configurations. In the first, we used a dual-element probe having a central 40 MHz element and an outer 20 MHz ring, both with a common focus. The second probe was a single-element focused 35 MHz transducer. We used an arbitrary waveform generator in combination with a broadband power amplifier to produce tonebursts to excite the radiation-force emitting element (which in the first configuration was the 20 MHz ring only). We measured the radiation force produced at a series of voltages and determined the maximum duration of the toneburst for each ...

Acoustic Emission and Residual Strength of Aircraft Tire Carcass Composites - SAE InternationalAcoustic Emission and Residual Strength of Aircraft Tire Carcass Composites - SAE International
The question of how the static strength of angle-plied nylon cord-reinforced rubber composites simulating aircraft tire carcass is affected by damage accumulation or materials degradation was examined in this study. Upon cyclic loading at 1 Hz, residual tensile strength was gradually lowered with the progression of fatigue damage. The degradation of the residual strength became more drastic toward the end of the fatigue life because of worsening delamination. In contrast, the residual strength after cyclic loading of 10 Hz exhibited a rapid decrease at the beginning of the fatigue life, presumably due to thermal degradation, and then remained virtually constant throughout the life. Acoustic emission (AE) activities were monitored to assess the extent of damage and to explore a possibility of indirect monitoring of residual strength of composites. Total cumulative values of AE hits, counts, and energy, which were defined at the final point of gross failure in static tension, were proportional to ...

Purpose: The aim of the study was to compare three different elastography methods, namely Strain Elastography (SE), Point Shear-Wave Elastography (pSWE) using Acoustic Radiation Force Impulse (ARFI)-Imaging and 2D-Shear Wave Elastography (2D-SWE), in the same study population for the differentiation of thyroid nodules. Materials and methods: All patients received a conventional ultrasound scan, SE and 2D-SWE, and all patients except for two received ARFI-Imaging. Cytology/histology of thyroid nodules was used as a reference method. SE measures the relative stiffness within the region of interest (ROI) using the surrounding tissue as reference tissue. ARFI mechanically excites the tissue at the ROI using acoustic pulses to generate localized tissue displacements. 2D-SWE measures tissue elasticity using the velocity of many shear waves as they propagate through the tissue. Results: 84 nodules (73 benign and 11 malignant) in 62 patients were analyzed. Sensitivity, specificity and NPV of SE were ...

Background: Acoustic Radiation Force Impulse (ARFI)-imaging is an ultrasound-based elastography method enabling quantitative measurement of tissue stiffness. The aim of the present study was to evaluate sensitivity and specificity of ARFI-imaging for differentiation of thyroid nodules and to compare it to the well evaluated qualitative real-time elastography (RTE). Methods: ARFI-imaging involves the mechanical excitation of tissue using acoustic pulses to generate localized displacements resulting in shear-wave propagation which is tracked using correlation-based methods and recorded in m/s. Inclusion criteria were: nodules $5 mm, and cytological/histological assessment. All patients received conventional ultrasound, real-time elastography (RTE) and ARFI-imaging. Results: One-hundred-fifty-eight nodules in 138 patients were available for analysis. One-hundred-thirty-seven nodules were benign on cytology/histology, and twenty-one nodules were malignant. The median velocity of ARFI-imaging in the ...

Semantics in Mobile Sensing - ODBMS.orgSemantics in Mobile Sensing - ODBMS.org
The dramatic progress of smartphone technologies has ushered in a new era of mobile sensing, where traditional wearable on-body sensors are being rapidly superseded by various embedded sensors in our smartphones. For example, a typical smartphone today, has at the very least a GPS, WiFi, Bluetooth, triaxial accelerometer, and gyroscope. Alongside, new accessories are emerging such as proximity, magnetometer, barometer, temperature, and pressure sensors. Even the default microphone can act as an acoustic sensor to track noise exposure for example. These sensors act as a lens to understand the users context along different dimensions.. Data can be passively collected from these sensors without interrupting the user. As a result, this new era of mobile sensing has fueled significant interest in understanding what can be extracted from such sensor data both instantaneously as well as considering volumes of time series from these sensors. For example, GPS logs can be used to determine ...
