Midbrain combinatorial code for temporal and spectral information in concurrent acoustic signals. (1/773)

All vocal species, including humans, often encounter simultaneous (concurrent) vocal signals from conspecifics. To segregate concurrent signals, the auditory system must extract information regarding the individual signals from their summed waveforms. During the breeding season, nesting male midshipman fish (Porichthys notatus) congregate in localized regions of the intertidal zone and produce long-duration (>1 min), multi-harmonic signals ("hums") during courtship of females. The hums of neighboring males often overlap, resulting in acoustic beats with amplitude and phase modulations at the difference frequencies (dFs) between their fundamental frequencies (F0s) and harmonic components. Behavioral studies also show that midshipman can localize a single hum-like tone when presented with a choice between two concurrent tones that originate from separate speakers. A previous study of the neural mechanisms underlying the segregation of concurrent signals demonstrated that midbrain neurons temporally encode a beat's dF through spike synchronization; however, spectral information about at least one of the beat's components is also required for signal segregation. Here we examine the encoding of spectral differences in beat signals by midbrain neurons. The results show that, although the spike rate responses of many neurons are sensitive to the spectral composition of a beat, virtually all midbrain units can encode information about differences in the spectral composition of beat stimuli via their interspike intervals (ISIs) with an equal distribution of ISI spectral sensitivity across the behaviorally relevant dFs. Together, temporal encoding in the midbrain of dF information through spike synchronization and of spectral information through ISI could permit the segregation of concurrent vocal signals.  (+info)

Desynchronizing responses to correlated noise: A mechanism for binaural masking level differences at the inferior colliculus. (2/773)

We examined the adequacy of decorrelation of the responses to dichotic noise as an explanation for the binaural masking level difference (BMLD). The responses of 48 low-frequency neurons in the inferior colliculus of anesthetized guinea pigs were recorded to binaurally presented noise with various degrees of interaural correlation and to interaurally correlated noise in the presence of 500-Hz tones in either zero or pi interaural phase. In response to fully correlated noise, neurons' responses were modulated with interaural delay, showing quasiperiodic noise delay functions (NDFs) with a central peak and side peaks, separated by intervals roughly equivalent to the period of the neuron's best frequency. For noise with zero interaural correlation (independent noises presented to each ear), neurons were insensitive to the interaural delay. Their NDFs were unmodulated, with the majority showing a level of activity approximately equal to the mean of the peaks and troughs of the NDF obtained with fully correlated noise. Partial decorrelation of the noise resulted in NDFs that were, in general, intermediate between the fully correlated and fully decorrelated noise. Presenting 500-Hz tones simultaneously with fully correlated noise also had the effect of demodulating the NDFs. In the case of tones with zero interaural phase, this demodulation appeared to be a saturation process, raising the discharge at all noise delays to that at the largest peak in the NDF. In the majority of neurons, presenting the tones in pi phase had a similar effect on the NDFs to decorrelating the noise; the response was demodulated toward the mean of the peaks and troughs of the NDF. Thus the effect of added tones on the responses of delay-sensitive inferior colliculus neurons to noise could be accounted for by a desynchronizing effect. This result is entirely consistent with cross-correlation models of the BMLD. However, in some neurons, the effects of an added tone on the NDF appeared more extreme than the effect of decorrelating the noise, suggesting the possibility of additional inhibitory influences.  (+info)

Early visual experience shapes the representation of auditory space in the forebrain gaze fields of the barn owl. (3/773)

Auditory spatial information is processed in parallel forebrain and midbrain pathways. Sensory experience early in life has been shown to exert a powerful influence on the representation of auditory space in the midbrain space-processing pathway. The goal of this study was to determine whether early experience also shapes the representation of auditory space in the forebrain. Owls were raised wearing prismatic spectacles that shifted the visual field in the horizontal plane. This manipulation altered the relationship between interaural time differences (ITDs), the principal cue used for azimuthal localization, and locations of auditory stimuli in the visual field. Extracellular recordings were used to characterize ITD tuning in the auditory archistriatum (AAr), a subdivision of the forebrain gaze fields, in normal and prism-reared owls. Prism rearing altered the representation of ITD in the AAr. In prism-reared owls, unit tuning for ITD was shifted in the adaptive direction, according to the direction of the optical displacement imposed by the spectacles. Changes in ITD tuning involved the acquisition of unit responses to adaptive ITD values and, to a lesser extent, the elimination of responses to nonadaptive (previously normal) ITD values. Shifts in ITD tuning in the AAr were similar to shifts in ITD tuning observed in the optic tectum of the same owls. This experience-based adjustment of binaural tuning in the AAr helps to maintain mutual registry between the forebrain and midbrain representations of auditory space and may help to ensure consistent behavioral responses to auditory stimuli.  (+info)

Single cortical neurons serve both echolocation and passive sound localization. (5/773)

The pallid bat uses passive listening at low frequencies to detect and locate terrestrial prey and reserves its high-frequency echolocation for general orientation. While hunting, this bat must attend to both streams of information. These streams are processed through two parallel, functionally specialized pathways that are segregated at the level of the inferior colliculus. This report describes functionally bimodal neurons in auditory cortex that receive converging input from these two pathways. Each brain stem pathway imposes its own suite of response properties on these cortical neurons. Consequently, the neurons are bimodally tuned to low and high frequencies, and respond selectively to both noise transients used in prey detection, and downward frequency modulation (FM) sweeps used in echolocation. A novel finding is that the monaural and binaural response properties of these neurons can change as a function of the sound presented. The majority of neurons appeared binaurally inhibited when presented with noise but monaural or binaurally facilitated when presented with the echolocation pulse. Consequently, their spatial sensitivity will change, depending on whether the bat is engaged in echolocation or passive listening. These results demonstrate that the response properties of single cortical neurons can change with behavioral context and suggest that they are capable of supporting more than one behavior.  (+info)

Functional selection of adaptive auditory space map by GABAA-mediated inhibition. (6/773)

The external nucleus of the inferior colliculus in the barn owl contains an auditory map of space that is based on the tuning of neurons for interaural differences in the timing of sound. In juvenile owls, this region of the brain can acquire alternative maps of interaural time difference as a result of abnormal experience. It has been found that, in an external nucleus that is expressing a learned, abnormal map, the circuitry underlying the normal map still exists but is functionally inactivated by inhibition mediated by gamma-aminobutyric acid type A (GABAA) receptors. This inactivation results from disproportionately strong inhibition of specific input channels to the network. Thus, experience-driven changes in patterns of inhibition, as well as adjustments in patterns of excitation, can contribute critically to adaptive plasticity in the central nervous system.  (+info)

Sensitivity to simulated directional sound motion in the rat primary auditory cortex. (7/773)

Sensitivity to simulated directional sound motion in the rat primary auditory cortex. This paper examines neuron responses in rat primary auditory cortex (AI) during sound stimulation of the two ears designed to simulate sound motion in the horizontal plane. The simulated sound motion was synthesized from mathematical equations that generated dynamic changes in interaural phase, intensity, and Doppler shifts at the two ears. The simulated sounds were based on moving sources in the right frontal horizontal quadrant. Stimuli consisted of three circumferential segments between 0 and 30 degrees, 30 and 60 degrees, and 60 and 90 degrees and four radial segments at 0, 30, 60, and 90 degrees. The constant velocity portion of each segment was 0.84 m long. The circumferential segments and center of the radial segments were calculated to simulate a distance of 2 m from the head. Each segment had two trajectories that simulated motion in both directions, and each trajectory was presented at two velocities. Young adult rats were anesthetized, the left primary auditory cortex was exposed, and microelectrode recordings were obtained from sound responsive cells in AI. All testing took place at a tonal frequency that most closely approximated the best frequency of the unit at a level 20 dB above the tuning curve threshold. The results were presented on polar plots that emphasized the two directions of simulated motion for each segment rather than the location of sound in space. The trajectory exhibiting a "maximum motion response" could be identified from these plots. "Neuron discharge profiles" within these trajectories were used to demonstrate neuron activity for the two motion directions. Cells were identified that clearly responded to simulated uni- or multidirectional sound motion (39%), that were sensitive to sound location only (19%), or that were sound driven but insensitive to our location or sound motion stimuli (42%). The results demonstrated the capacity of neurons in rat auditory cortex to selectively process dynamic stimulus conditions representing simulated motion on the horizontal plane. Our data further show that some cells were responsive to location along the horizontal plane but not sensitive to motion. Cells sensitive to motion, however, also responded best to the moving sound at a particular location within the trajectory. It would seem that the mechanisms underlying sensitivity to sound location as well as direction of motion converge on the same cell.  (+info)

Influence of head position on the spatial representation of acoustic targets. (8/773)

Sound localization in humans relies on binaural differences (azimuth cues) and monaural spectral shape information (elevation cues) and is therefore the result of a neural computational process. Despite the fact that these acoustic cues are referenced with respect to the head, accurate eye movements can be generated to sounds in complete darkness. This ability necessitates the use of eye position information. So far, however, sound localization has been investigated mainly with a fixed head position, usually straight ahead. Yet the auditory system may rely on head motor information to maintain a stable and spatially accurate representation of acoustic targets in the presence of head movements. We therefore studied the influence of changes in eye-head position on auditory-guided orienting behavior of human subjects. In the first experiment, we used a visual-auditory double-step paradigm. Subjects made saccadic gaze shifts in total darkness toward brief broadband sounds presented before an intervening eye-head movement that was evoked by an earlier visual target. The data show that the preceding displacements of both eye and head are fully accounted for, resulting in spatially accurate responses. This suggests that auditory target information may be transformed into a spatial (or body-centered) frame of reference. To further investigate this possibility, we exploited the unique property of the auditory system that sound elevation is extracted independently from pinna-related spectral cues. In the absence of such cues, accurate elevation detection is not possible, even when head movements are made. This is shown in a second experiment where pure tones were localized at a fixed elevation that depended on the tone frequency rather than on the actual target elevation, both under head-fixed and -free conditions. To test, in a third experiment, whether the perceived elevation of tones relies on a head- or space-fixed target representation, eye movements were elicited toward pure tones while subjects kept their head in different vertical positions. It appeared that each tone was localized at a fixed, frequency-dependent elevation in space that shifted to a limited extent with changes in head elevation. Hence information about head position is used under static conditions too. Interestingly, the influence of head position also depended on the tone frequency. Thus tone-evoked ocular saccades typically showed a partial compensation for changes in static head position, whereas noise-evoked eye-head saccades fully compensated for intervening changes in eye-head position. We propose that the auditory localization system combines the acoustic input with head-position information to encode targets in a spatial (or body-centered) frame of reference. In this way, accurate orienting responses may be programmed despite intervening eye-head movements. A conceptual model, based on the tonotopic organization of the auditory system, is presented that may account for our findings.  (+info)

What is sound? (IX) Sound localization and vision | Romain Brette
In this post, I want to come back on a remark I made in a previous post, on the relationship between vision and spatial hearing. It appears that my account of the comparative study of Heffner and Heffner (Heffner & Heffner, 1992) was not accurate. Their findings are in fact even more interesting than I thought. They find that sound localization acuity across mammalian species is best predicted not by visual acuity, but by the width of the field of best vision.. Before I comment on this result, I need to explain a few details. Sound localization acuity was measured behaviorally in a left/right discrimination task near the midline, with broadband sounds. The authors report this discrimination threshold for 23 mammalian species, from gerbils to elephants. They then try to relate this value to various other quantities: the largest interaural time difference (ITD), which is directly related to head size, visual acuity (highest angular density of retinal cells), whether the animals are predatory or ...

N2 - State-of-the-art hearing AIDS (HAs) can connect to a wireless microphone worn by a talker of interest.This ability allows HAs to have access to almost noise-free sound signals of the target talker.In this paper, we aim to estimate the direction of arrival (DoA) of the target signal,given access to the noise-free target signal. Knowing the DoA of the target signal enables HAs to spatialize the wirelessly received target signals.The proposed estimator is based on a maximum likelihood (ML) approach and a database of DoA-dependent relative transfer functions (RTFs),and it supports both monaural and binaural microphone array configurations. For binaural configurations,we propose an information fusion strategy, which decreases the number of parameters required to be wirelessly transferred between the HAs. Further, ...

Plus itPlus it
Sensory systems evolved to encode biologically important information carried by noisy signals. Elucidating mechanisms of robust sensory coding remains a basic problem in neuroscience (Rieke et al., 1999). One highly conserved sensory capacity that lends itself to the study of this problem is that of sound source localization. Sound localization subserves predator avoidance, prey capture, situational awareness, and communication. In mammals, relative differences in the time of arrival and intensity of sound at the two ears, interaural time differences (ITDs) and interaural level differences (ILDs), respectively, provide the major cues to sound source location in the horizontal plane (Grothe et al., 2010). ITDs are encoded primarily by neurons of the medial superior olive (MSO), which are exquisitely sensitive to the relative timing of the signal at each ear (Goldberg and Brown, 1969). However, natural perturbations in the relative timing of the signal at each ear (e.g., due to reverberation) ...

Atypical vertical sound localization and sound-onset sensitivity in people with autism spectrum disorders - Journal of...Atypical vertical sound localization and sound-onset sensitivity in people with autism spectrum disorders - Journal of...
Background: Autism spectrum disorders (ASDs) are associated with auditory hyper- or hyposensitivity; atypicalities in central auditory processes, such as speech-processing and selective auditory attention; and neural connectivity deficits. We sought to investigate whether the low-level integrative processes underlying sound localization and spatial discrimination are affected in ASDs.. Methods: We performed 3 behavioural experiments to probe different connecting neural pathways: 1) horizontal and vertical localization of auditory stimuli in a noisy background, 2) vertical localization of repetitive frequency sweeps and 3) discrimination of horizontally separated sound stimuli with a short onset difference (precedence effect).. Results: Ten adult participants with ASDs and 10 healthy control listeners participated in experiments 1 and 3; sample sizes for experiment 2 were 18 adults with ASDs and 19 controls. Horizontal localization was unaffected, but vertical localization performance was ...

The precedence effect and its buildup and breakdown in ferrets and humans. - Oxford Neuroscience
Although many studies have examined the precedence effect (PE), few have tested whether it shows a buildup and breakdown in nonhuman animals comparable to that seen in humans. These processes are thought to reflect the ability of the auditory system to adjust to a listeners acoustic environment, and their mechanisms are still poorly understood. In this study, ferrets were trained on a two-alternative forced-choice task to discriminate the azimuthal direction of brief sounds. In one experiment, pairs of noise bursts were presented from two loudspeakers at different interstimulus delays (ISDs). Results showed that localization performance changed as a function of ISD in a manner consistent with the PE being operative.

Department for Zoology and Animal Physiology: Neurobiology of sound localization
The network underlying sound localization is similar in all vertebrates, although the exact mechanisms underlying the use, the neural extraction and the neural representation may be different in different vertebrate classes. This is not surprising, because, for example birds and mammals have independently developed for several hundreds of millions of years. We study the representation of sound-localization cues at several levels, from the first station of binaural detection in nucleus laminaris to the midbrain-nucleus colliculus inferior, where a first remodeling of the representation occurs and the forebrain, where a further remodeling occurs. We mainly use extracellular recording techniques and combine these with theoretical results. The groups of Thomas Kuenzel and Marcus Wirth complement our approach by working with chicken, an auditory generalist, on the molecular and cellular levels. ...

Sound localization - WikipediaSound localization - Wikipedia
The term binaural literally signifies to hear with two ears, and was introduced in 1859 to signify the practice of listening to the same sound through both ears, or to two discrete sounds, one through each ear. It was not until 1916 that Carl Stumpf (1848-1936), a German philosopher and psychologist, distinguished between dichotic listening, which refers to the stimulation of each ear with a different stimulus, and diotic listening, the simultaneous stimulation of both ears with the same stimulus.[27] Later, it would become apparent that binaural hearing, whether dichotic or diotic, is the means by which sound localization occurs.[27][28][page needed] Scientific consideration of binaural hearing began before the phenomenon was so named, with speculations published in 1792 by William Charles Wells (1757-1817) based on his research into binocular vision.[29] Giovanni Battista Venturi (1746-1822) conducted and described experiments in which people tried to localize a sound using both ears, or ...

Forgetting what was where: the fragility of object-location binding. - Department of Experimental Psychology
Although we frequently take advantage of memory for objects locations in everyday life, understanding how an objects identity is bound correctly to its location remains unclear. Here we examine how information about object identity, location and crucially object-location associations are differentially susceptible to forgetting, over variable retention intervals and memory load. In our task, participants relocated objects to their remembered locations using a touchscreen. When participants mislocalized objects, their reports were clustered around the locations of other objects in the array, rather than occurring randomly. These swap errors could not be attributed to simple failure to remember either the identity or location of the objects, but rather appeared to arise from failure to bind object identity and location in memory. Moreover, such binding failures significantly contributed to decline in localization performance over retention time. We conclude that when objects are forgotten they do not

Morphological variation in the nucleus laminaris in birdsMorphological variation in the nucleus laminaris in birds
Interaural time differences (lTDs) are one of the cues used for binaural sound localisation. In birds, RDs are computed in nucleus laminaris (NL), where a place code of azimuthal location first emerges. In chickens, NL consists of a monolayer of bitufted cells that receive segregated inputs from ipsi- and contralateral nucleus magnocellularis (NM). In ham owls, the monolayer organisation, the bitufted morphology, and the segregation of inputs have been lost, giving rise to a derived organisation that is accompanied by a reorganisation of the auditory place code. Although chickens and ham owls have been the traditional experimental models in which to study lTD coding, they represent distant evolutionary lineages with very different auditory specialisations. Here we examined the structure of NL in several bird lineages. We have found only two NL morphotypes, one of which appears to have emerged in association with high frequency hearing ...

Iris View Profile
The auditory circuit that we are studying helps to locate sound sources in space and illustrates beautifully how development is instrumental in shaping function. A major cue for an animal to locate sound sources compares the arrival time of the sound at the two ears. The time difference in sound reaching each ear, termed interaural time difference (ITD), varies from zero (sound directly ahead) to approximately 300 microseconds (depending on the size of head). The circuit operates as an AND logical gate where synaptic input from the ear closest to the sound sets up a map of space along an array of neurons which is compared to synaptic input from the ear furthest away from the sound. This identifies the location of sound in a subset of neurons along this array through dendritic integration to detect temporal coincidence of the two inputs. This calculation is performed at each characteristic frequency of sound using different arrays of neurons that are juxtaposed to form a sheet of cells in the ...

United States Patent 3,423,543 LOUDSPEAKER WITH PIEZOELECTRIC WAFER DRIVING ELEMENTS Harry W. Kompanek, 153 Rametto Road, Santa Barbara, Calif. 93103 Filed June 24, 1965, Ser. No. 466,599 US. Cl. 179-410 Int. Cl. Htl4r 15/00 Claims ABSTRACT OF THE DTSCLQSURE This invention relates to a loudspeaker and more particularly to a loudspeaker driven by piezoelectric means. As is well known, a piezoelectric wafer such as a barium titanate ceramic, produces an electric voltage when it is mechanically deformed. Conversely, when an AC. voltage is applied across the wafer, the wafer is mechanically deformed and tends to cup. When the piezoelectric wafer is secured to a member such as a plate and an A.C. voltage is applied across the wafer, the wafer causes the entire plate to cup back and forth and to produce sound. As the characteristics of the deformations or vibrations in the plate depend upon the characteristics of the voltage applied across the piezoelectric wafer, sound of substantially any frequency ...

Publications - Dr Dan GoodmanPublications - Dr Dan Goodman
Goodman DFM, Brette R, 2010, Spike-timing-based computation in sound localization., PLoS Comput Biol, Vol: 6 Spike timing is precise in the auditory system and it has been argued that it conveys information about auditory stimuli, in particular about the location of a sound source. However, beyond simple time differences, the way in which neurons might extract this information is unclear and the potential computational advantages are unknown. The computational difficulty of this task for an animal is to locate the source of an unexpected sound from two monaural signals that are highly dependent on the unknown source signal. In neuron models consisting of spectro-temporal filtering and spiking nonlinearity, we found that the binaural structure induced by spatialized sounds is mapped to synchrony patterns that depend on source location rather than on source signal. Location-specific synchrony patterns would then result in the activation of location-specific assemblies of postsynaptic neurons. We ...

A concept-based system for the live diffusion of sound via multiple loudspeakers - White Rose Research OnlineA concept-based system for the live diffusion of sound via multiple loudspeakers - White Rose Research Online
This paper presents a conceptual framework for sound diffusion: the process of presenting multiple channels of audio to an audience in a live performance context, via loudspeakers. Terminology that allows us to concisely describe the task of sound diffusion is defined. The conceptual model is described using this terminology. The model allows audio channels (sources) and loudspeakers (destinations) to be grouped logically, which, in turn, allows for sophisticated abstract methods of control that supercede the restrictive one-fader-one-loudspeaker approach. The Resound project - an open source software initiative conceived to implement and further develop the conceptual model - is introduced. The aim is, through further theoretical and practice led research into the conceptual model and software respectively, to address the technical, logistical and aesthetic issues inherent in the process of sound diffusion.. ...

Improving the Morse Intercept Operators Audio Display
This thesis improves the audio display for multiple Morse communications. Factors considered to improve the audio display are frequency of source, volume level of source, and methods of unmasking. The best frequency and volume level of a Morse source is 500 Hz at 70 dB sound pressure level. Two types of masking are researched frequency masking and expectation driven masking. Experiments showed by amplifying high pitched sources the effects of frequency masking are minimized. Other methods to compensate for frequency masking are 3-D sound and the placement of a source out of phase between the ears. Morse code recognition at 500 Hz is greatest when presented at the NO S-pi condition. Greatest unmasking for broadband signals occurs at 3-D locations between 60 and 90 deg where the largest ITD interaural time difference exists. This thesis theorizes and confirms that greatest unmasking of a source tone in 3-D sound corresponds to the spatial location that gives an ITD equal to a 180 deg phase shift for that

For the spatial task, participants navigated a path through virtual space; for the procedural task, they indicated under which of four position markers a dot appeared by rapidly pressing a keystroke. For the unrelated oddball task, participants lay in the scanner and mentally counted the deviant sounds embedded in a monotonous soundtrack. These oddball sessions occurred immediately before a task providing baseline brain activity immediately after a 30-minute training session, and again after a 30-minute rest period. A short behavioral test followed the last oddball session, then participants were scanned a fourth time while performing their task to identify brain regions associated with each task. Two weeks later, individuals were tested on the alternate task, so the researchers could compare post-training modulated brain activity associated with each task ...

In summary, GW serves to integrate many competing and cooperating networks of processes. Global behavior will be driven by a myriad of local micro-behaviors rather than whats happening in current networks, where a former built knowledge representation is used to manage the networks behavior. Practically the approach permits to rehearse global behaviors prior enacting local processes; said behaviors are evaluated, and the relative salience of a set of concurrently executable actions can be modulated as a result: those behaviors whose outcome is associated to a gain (or reward) become more and more salient and, at the end, selected and executed (e.g. with winner-take-all-strategy ...

[...] precedence based on age is the fairest system. Why have a precedence system at all (you may ask)? Because the absence of an accepted one results in the me-first system of shoving. Miss Manners only hopes that by that time, the concept of respect for the elderly will not have been killed off by misplaced vanity.

basic health: How it Works Ultrasoundbasic health: How it Works Ultrasound
Ultrasound, also called sonography or ultrasonography, it requires disclosure of certain body parts to high-frequency sound waves to produce images from inside the body. Ultrasound does not use ionizing radiation (used in X-rays). Because ultrasound images are captured in real time, can show the structure and movement of internal organs, and blood flowing through blood vessels ...

Ultrasound imaging, or sonography, produces images of the inside of the body using high-frequency sound waves. These images are captured in real-time, and are able to show the structure and movement of the organs.. Ultrasound imaging can be used to monitor and diagnose a wide range of conditions within nearly any system of the body. This test may be performed on patients experiencing pain, swelling or infection in a certain area of the body ...

  • Today I'm going to walk you through my experience trying to localize the source of a sound using Arduino. (42bots.com)
  • Whichever input is higher determines the source direction of the sound. (42bots.com)
  • On the practical side this proves to be not that useful as it requires a huge amount of sound isolation between the 2 microphones, or the sound source to be extremely close to one of the microphones in order to give a reliable reading. (42bots.com)
  • Also, what you get is normally a binary result "Left or Right" and I was looking for something a bit more precise, giving me an angle to the sound source. (42bots.com)
  • Knowing that just reading the output levels in 2 two microphones to determine direction would not be enough, my approach was to determine how long it took for the sound to reach each microphone, whichever sensor is triggered first defines the side (left/right) and the time difference or phase shift between the 2 microphones would allow me to triangulate the sound source… at least that was the theory. (42bots.com)

  • Age-related hearing loss first affects the ability to hear high-frequency sounds, such as speech. (medlineplus.gov)
  • As the hearing loss worsens, it affects more frequencies of sound, making it difficult to hear more than just speech. (medlineplus.gov)

  • An algorithm for the robust localization of a vehicle using both displacement tracking and sound localization is proposed. (elsevier.com)
System5

Propagation1
  • For example, sound moving through wind will have its speed of propagation increased by the speed of the wind if the sound and wind are moving in the same direction. (wikipedia.org)
Hearing7
  • Hypothesis: Underwater hearing acuity and sound localization are improved by the presence of an air interface around the pinnae and inside the external ear canals. (semanticscholar.org)
  • Studies have demonstrated that conventional hearing protectors interfere with sound localization. (who.int)
  • Sound Localization in Patients With Congenital Unilateral Conductive Hearing Loss With a Transcutaneous Bone Conduction Implant. (bvsalud.org)

  • 1) Spatial Hearing: We are exploring the auditory cortical mechanisms that enable a listener to pick a sound out of a complex auditory scene on the basis of the sound's location. (uci.edu)
  • That's what the wind does on your hearing aid, even a light breeze can sound like a raging tornado on many hearing aids. (hearingaidknow.com)
  • This extra microphone in the M&RIE fixes that problem, meaning us hearing aid users again get the benefit of having radar-shaped ears to pick up sounds. (hearingaidknow.com)
Particles2

  • Microphones are nothing more than sensors (transducers) that will convert the sound waves into an electric signal. (42bots.com)
  • The time difference between the beginning of the waves in the 2 channels should allow for triangulation considering the speed of sound. (42bots.com)
  • In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimeters (0.67 in). (wikipedia.org)
