Coding of sound envelopes by inhibitory rebound in neurons of the superior olivary complex in the unanesthetized rabbit. (1/910)

Most natural sounds (e.g., speech) are complex and have amplitude envelopes that fluctuate rapidly. A number of studies have examined the neural coding of envelopes, but little attention has been paid to the superior olivary complex (SOC), a constellation of nuclei that receive information from the cochlear nucleus. We studied two classes of predominantly monaural neurons: those that displayed a sustained response to tone bursts and those that gave only a response to the tone offset. Our results demonstrate that the off neurons in the SOC can encode the pattern of amplitude-modulated sounds with high synchrony that is superior to sustained neurons. The upper cutoff frequency and highest modulation frequency at which significant synchrony was present were, on average, slightly higher for off neurons compared with sustained neurons. Finally, most sustained and off neurons encoded the level of pure tones over a wider range of intensities than those reported for auditory nerve fibers and cochlear nucleus neurons. A traditional view of inhibition is that it attenuates or terminates neural activity. Although this holds true for off neurons, the robust discharge when inhibition is released adds a new dimension. For simple sounds (i.e., pure tones), the off response can code a wide range of sound levels. For complex sounds, the off response becomes entrained to each modulation, resulting in a precise temporal coding of the envelope. (+info)

Communication signals and sound production mechanisms of mormyrid electric fish. (2/910)

The African weakly electric fishes Pollimyrus isidori and Pollimyrus adspersus (Mormyridae) produce elaborate acoustic displays during social communication in addition to their electric organ discharges (EODs). In this paper, we provide new data on the EODs of these sound-producing mormyrids and on the mechanisms they use to generate species-typical sounds. Although it is known that the EODs are usually species-specific and sexually dimorphic, the EODs of closely related sound-producing mormyrids have not previously been compared. The data presented demonstrate that there is a clear sexual dimorphism in the EOD waveform of P. isidori. Females have a multi-phasic EOD that is more complex than the male's biphasic EOD. In this respect, P. isidori is similar to its more thoroughly studied congener P. adspersus, which has a sexually dimorphic EOD. The new data also reveal that the EODs of these two species are distinct, thus showing for the first time that species-specificity in EODs is characteristic of these fishes, which also generate species-specific courtship sounds. The sound-generating mechanism is based on a drumming muscle coupled to the swimbladder. Transverse sections through decalcified male and female P. adspersus revealed a muscle that envelops the caudal pole of the swimbladder and that is composed of dorso-ventrally oriented fibers. The muscle is five times larger in males (14.5+/-4.4 microl, mean +/- s.d.) than in females (3.2+/-1.8 microl). The fibers are also of significantly larger diameter in males than in females. Males generate courtship sounds and females do not. The function of the swimbladder muscle was tested using behavioral experiments. Male P. adspersus normally produce acoustic courtship displays when presented with female-like electrical stimuli. However, local anesthesia of the swimbladder muscle muted males. In control trials, males continued to produce sounds after injection of either lidocaine in the trunk muscles or saline in the swimbladder muscles. (+info)

Sensitivity to simulated directional sound motion in the rat primary auditory cortex. (3/910)

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)

Single-unit responses in the inferior colliculus of decerebrate cats. I. Classification based on frequency response maps. (4/910)

This study proposes a classification system for neurons in the central nucleus of the inferior colliculus (ICC) that is based on excitation and inhibition patterns of single-unit responses in decerebrate cats. The decerebrate preparation allowed extensive characterization of physiological response types without the confounding effects of anesthesia. The tone-driven discharge rates of individual units were measured across a range of frequencies and levels to map excitatory and inhibitory response areas for contralateral monaural stimulation. The resulting frequency response maps can be grouped into the following three populations: type V maps exhibit a wide V-shaped excitatory area and no inhibition; type I maps show a more restricted I-shaped region of excitation that is flanked by inhibition at lower and higher frequencies; and type O maps display an O-shaped island of excitation at low stimulus levels that is bounded by inhibition at higher levels. Units that produce a type V map typically have a low best frequency (BF: the most sensitive frequency), a low rate of spontaneous activity, and monotonic rate-level functions for both BF tones and broadband noise. Type I and type O units have BFs that span the cat's range of audible frequencies and high rates of spontaneous activity. Like type V units, type I units are excited by BF tones and noise at all levels, but their rate-level functions may become nonmonotonic at high levels. Type O units are inhibited by BF tones and noise at high levels. The existence of distinct response types is consistent with a conceptual model in which the unit types receive dominant inputs from different sources and shows that these functionally segregated pathways are specialized to play complementary roles in the processing of auditory information.

Conductive hearing loss produces a reversible binaural hearing impairment. (5/910)

Conductive hearing loss, produced by otitis media with effusion, is widespread in young children. However, little is known about its short- or long-term effects on hearing or the brain. To study the consequences of a conductive loss for the perception and processing of sounds, we plugged the left ear canal of ferrets for 7-15 months during either infancy or adulthood. Before or during plugging, the ferrets were trained to perform a binaural task requiring the detection of a 500 Hz tone, positioned 90 degrees to the right, that was masked by two sources of broad-band noise. In one condition ("control"), both noise sources were 90 degrees right and, in the second condition ("bilateral"), one noise source was moved to 90 degrees left. Normal ferrets showed binaural unmasking: tone detection thresholds were lower (mean 10.1 dB) for the bilateral condition than for the control condition. Both groups of ear-plugged ferrets had reduced unmasking; the mean residual unmasking was 2.3 dB for the infant and 0.7 dB for the adult ear-plugged animals. After unplugging, unmasking increased in both groups (infant, 7.1 dB; adult, 6.9 dB) but not to normal levels. Repeated testing during the 22 months after unplugging revealed a gradual return to normal levels of unmasking. These results show that a unilateral conductive hearing loss, in either infancy or adulthood, impairs binaural hearing both during and after the hearing loss. They show scant evidence for adaptation to the plug and demonstrate a recovery from the impairment that occurs over a period of several months after restoration of normal peripheral function.

Mosquito hearing: sound-induced antennal vibrations in male and female Aedes aegypti. (6/910)

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)

Bilateral ablation of auditory cortex in Mongolian gerbil affects discrimination of frequency modulated tones but not of pure tones. (7/910)

This study examines the role of auditory cortex in the Mongolian gerbil in differential conditioning to pure tones and to linearly frequency-modulated (FM) tones by analyzing the effects of bilateral auditory cortex ablation. Learning behavior and performance were studied in a GO/NO-GO task aiming at avoidance of a mild foot shock by crossing a hurdle in a two-way shuttle box. Hurdle crossing as the conditioned response to the reinforced stimulus (CR+), as false alarm in response to the unreinforced stimulus (CR-), intertrial activity, and reaction times were monitored. The analysis revealed no effects of lesion on pure tone discrimination but impairment of FM tone discrimination. In the latter case lesion effects were dependent on timing of lesion relative to FM tone discrimination training. Lesions before training in naive animals led to a reduced CR+ rate and had no effect on CR- rate. Lesions in pretrained animals led to an increased CR- rate without effects on the CR+ rate. The results suggest that auditory cortex plays a more critical role in discrimination of FM tones than in discrimination of pure tones. The different lesion effects on FM tone discrimination before and after training are compatible with both the hypothesis of a purely sensory deficit in FM tone processing and the hypothesis of a differential involvement of auditory cortex in acquisition and retention, respectively.

Contractile properties of muscles used in sound production and locomotion in two species of gray tree frog. (8/910)

The sound-producing muscles of frogs and toads are interesting because they have been selected to produce high-power outputs at high frequencies. The two North American species of gray tree frog, Hyla chrysoscelis and Hyla versicolor, are a diploid-tetraploid species pair. They are morphologically identical, but differ in the structure of their advertisement calls. H. chrysoscelis produces very loud pulsed calls by contracting its calling muscles at approximately 40 Hz at 20 degrees C, whereas, H. versicolor operates the homologous muscles at approximately 20 Hz at this temperature. This study examined the matching of the intrinsic contractile properties of the calling muscles to their frequency of use. I measured the isotonic and isometric contractile properties of two calling muscles, the laryngeal dilator, which presumably has a role in modulating call structure, and the external oblique, which is one of the muscles that provides the mechanical power for calling. I also examined the properties of the sartorius as a representative locomotor muscle. The calling muscles differ greatly in twitch kinetics between the two species. The calling muscles of H. chrysoscelis reach peak tension in a twitch after approximately 15 ms, compared with 25 ms for the same muscles in H. versicolor. The muscles also differ significantly in isotonic properties in the direction predicted from their calling frequencies. However, the maximum shortening velocities of the calling muscles of H. versicolor are only slightly lower than those of the comparable muscles of H. chrysoscelis. The calling muscles have similar maximum shortening velocities to the sartorius, but have much flatter force-velocity curves, which may be an adaptation to their role in cyclical power output. I conclude that twitch properties have been modified more by selection than have intrinsic shortening velocities. This difference corresponds to the differing roles of shortening velocity and twitch kinetics in determining power output at differing frequencies. (+info)

The human ear is not equally sensitive to sounds (tones) of the same sound pressure levels but different frequencies . (europa.eu)
The loudness of a sound is not equal with its sound pressure level and differs for different frequencies. (europa.eu)
As it could be seen in the figure below, the frequencies 3-4 kHz are the most sensitive within sound frequency range from 20 Hz to 20 kHz that can be heard by human ear. (europa.eu)
For frequencies lower than 3-4 kHz and higher sound frequencies, the ear becomes less sensitive. (europa.eu)
Also, many sound players like to deemphasize low frequencies. (usda.gov)
If your player has an equalizer and you can't hear the sounds, turn up the frequencies between 600 and 1500 Hz. (usda.gov)
Ultrasound is sound with frequencies above the range of human hearing-that is, above 20,000 hertz. (howstuffworks.com)
The term "ultrasonic" applied to sound refers to anything above the frequencies of audible sound , and nominally includes anything over 20,000 Hz. (gsu.edu)
Most sound-absorbing materials are nonlinear, in that they do not absorb the same fraction of acoustic waves of all frequencies. (britannica.com)
This means that the lower frequencies of a voice bend around a corner more readily than the higher frequencies, giving the diffracted voice a "muffled" sound. (britannica.com)
From an infant's gurgles over a baby monitor to the roar of the crowd in a stadium to the sub-bass frequencies produced by sound systems in the disco era, sound-not necessarily aestheticized as music-is inextricably part of the many domains of popular culture. (mit.edu)
In order to simulate low frequencies that aren't actually there, the corresponding range is raised by an extreme 250 Hz, yielding a cardboard sound that's noisy and rumbling like the cheap equipment found blaring at parties. (tomshardware.com)

The dark waters of Puget Sound (center) stand out in this image from July 9th, 2003. (nasa.gov)
As this rain falls on our hard urban surfaces, it picks up pollutants that have been building up throughout our summer, washing this toxic mixture into our waterways and into Puget Sound. (nature.org)
Stormwater is the No. 1 polluter of Puget Sound, harming the health of our ecosystems and our iconic salmon species. (nature.org)
We are excited to announce the first six on-the-ground projects selected to receive funding through a competitive Puget Sound-wide request for proposals process by an advising committee made up of partners from around the region. (nature.org)
Through this effort, we are catalyzing on-the-ground tree-planting projects around Puget Sound that are planting trees for the health of their communities and for the water flowing into Puget Sound," says Chris Hilton, Puget Sound urban partnership director for The Nature Conservancy in Washington. (nature.org)
By investing in diverse projects and bringing together partners from across the region, we can take an important step for restoring the health of Puget Sound. (nature.org)
Take a look at these exciting projects - and sign-up to stay in the loop about volunteering for urban tree projects around Puget Sound. (nature.org)
An organization focused on supporting the health of salmon and orcas, Whale Scout engages volunteers throughout Puget Sound to support restoration work that reduces stormwater runoff, shades salmon habitat and provides on-shore whale watchers opportunities to take action to improve conditions for killer whales. (nature.org)
Olympia marked the southern extent of a towering mile-high glacier that rolled down from Canada, carving out the Puget Sound. (kickstarter.com)

Correlation between noise effect hearing loss and sound exposure levels measured in A, B, or C weightings would not be very different. (europa.eu)
Most of the sound files in the several pages of this library were selected from noise-free sections of recorded signal, but you can hear some typical background noises mixed with insect sounds at I below. (usda.gov)

Interactive, multi-disciplinary, STEM lessons and activities introduce students and teachers to the study of the New York City sound environment, New York City's Noise Code, and the public health issues, both mental and physical, associated with noise. (nyc.gov)
Below are free education materials for students and teachers which include presentations, glossaries, suggested reading lists, worksheets, and much more for the understanding of sound and noise. (nyc.gov)
Why Teach about Sound and Noise? (nyc.gov)
Absorption of undesirable sound, such as that from machines in factories, is critical to the health of workers, and noise control in architectural and industrial acoustics has expanded to become an important field of environmental engineering . (britannica.com)
The NIOSH Sound Level Meter (SLM) app combines the best features of professional sound levels meters and noise dosimeters into a simple, easy-to-use package. (cdc.gov)
The app also reports the main metrics that are of importance for proper occupational noise measurements - mainly the run time (total time), the A-weighted Equivalent Sound Level (LAeq), the Maximum Level measured during the current run time, the C-weighted Peak Sound Pressure Level (LCpeak), the Time-Weighted Average (TWA) and Dose. (cdc.gov)
NIOSH hearing loss researchers collaborated with an app developer, EA LAB, to create an iOS based sound level meter app that measures and characterizes occupational noise exposure similar to professional instruments. (cdc.gov)
Marc says the suffering that we don't see still makes a sort of sound - a subtle, soft noise, nothing like the cries of screams that we might think of - more the slight scrape of a hat doffed by a quiet man, ignored as he stands back to let a lovely woman pass, her dress just brushing his coat. (livejournal.com)
Xonar AE delivers 7.1-channel, 192kHz/24-bit Hi-Res audio output with a high 110dB signal-to-noise ratio (SNR), and comes with a built-in 150ohm headphone amplifier that provides rich, detailed sound and defined bass. (asus.com)
The Determination of Sound Exposures (DOSES) software was developed for use by mine management and safety personnel to simplify the record-keeping and analysis associated with time-motion studies and worker noise exposures, making it easier to identify and solve noise problems. (cdc.gov)
At the same time, noise measurements are collected with a dosimeter or sound level meter (SLM). (cdc.gov)
She or he will also ask you to describe the noise you're hearing (including its pitch and sound quality, and whether it's constant or periodic, steady or pulsatile) and the times and places in which you hear it. (amazonaws.com)
Most of the people who drive an electric car for the first time find the lack of noise or sound to be quite shocking. (bmwblog.com)
According to Marsha Green, founder of the Ocean Mammal Institute and the International Ocean Noise Coalition, the Navy is making the problem sound more complicated than it is. (honoluluweekly.com)
Based on the phenomenal MASH noise shaping technology used for many years in Panasonic products, the LincsD-Amp markedly reduces jitter and distortion that can affect audio clarity, producing pure brilliant sound. (panasonic.com)
Then, a mathematical expression is developed which combines the dissipative and sound transmission loss performance to determine the total noise reduction provided in the vehicle. (sae.org)

As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound , thus forming the sound wave. (wikipedia.org)
It turns electrical energy back into sound by using electricity to make the air around it vibrate. (factmonster.com)
Inside it, sound waves cause a flexible disc (diaphragm) to vibrate. (factmonster.com)
Your inner ear's cochlea is lined with thousands of fine, hair-like cells that vibrate when exposed to sound waves. (amazonaws.com)
If one of the subwoofers is placed in the trunk of a car, the car literally will vibrate from the sound because of the power packed into the bass. (chicagotribune.com)

This subjective or perceived magnitude of a sound by an individual is called its loudness. (europa.eu)
In order to assess loudness of a sound the isophonic curves are explored. (europa.eu)
While sound pressure measurements should give a reading of the sound pressure in dB SPL , in the context of human hearing it is more practical to provide also a value which corresponds more closely to the hearing sensation or loudness in phones. (europa.eu)
The A, B, and C filters used currently in sound-level meters were aimed at mimicking isoloudness curves over frequency under different conditions of sound intensities, i.e. for sounds of low, medium, and high loudness levels, respectively (IEC 651, 1979). (europa.eu)
Loudness refers to how strong a sound seems when we hear it. (howstuffworks.com)
Sound can be described in terms of pitch-from the low rumble of distant thunder to the high-pitched buzzing of a mosquito-and loudness. (howstuffworks.com)
Objective, measurable qualities of sound include frequency and intensity, which are related to pitch and loudness. (howstuffworks.com)
Sound intensity (loudness) is measured is decibels after Bell, the inventer of the sound-only telephone. (conservapedia.com)

The sound source creates vibrations in the surrounding medium. (wikipedia.org)

In order to illustrate some of what can go wrong with sound design, or the deliberate modification of sound reproduction through under- or over-emphasizing individual frequency ranges, we selected two headsets to serve as examples. (tomshardware.com)
The options that ODMs offer, such as various openings for correcting attenuation, modify the sound by either raising or lowering each frequency range. (tomshardware.com)

In physics , sound is a vibration that propagates as an acoustic wave , through a transmission medium such as a gas, liquid or solid. (wikipedia.org)
One hertz equals one cycle (vibration, or sound wave) per second. (howstuffworks.com)
One important process is the direct conduction of the vibration into the medium as heat , caused by the conversion of the coherent molecular motion of the sound wave into incoherent molecular motion in the air or other absorptive material. (britannica.com)
Sound is caused by the vibration of an object, and its effect is a physiological occurrence in the brain, which also may occur to some extent when reading words or music. (conservapedia.com)

Some of the sounds are low in intensity, and it may be necessary to turn up the speaker volume to hear them. (usda.gov)
Decibel (dB) is the unit used to measure the intensity of a sound. (howstuffworks.com)
Intensity of a sound is a measure of the power of its waves. (howstuffworks.com)
The magnetostrictive transducers can be used to produce high intensity ultrasonic sound in the 20-40 kHz range for ultrasonic cleaning and other mechanical applications. (gsu.edu)
In addition to the geometric decrease in intensity caused by the inverse square law, a small part of a sound wave is lost to the air or other medium through various physical processes. (britannica.com)
Sound wave strength or intensity also does not match what it sounds like. (conservapedia.com)
Other forms of sound sensitivity include hyperacusis (a negative reaction to sound due to particular physical characteristics, like volume, type, and intensity) and phonophobia (a fear of certain sounds). (medicinenet.com)
This condition usually entails a number of negative reactions, like anger, agitation, and hatred of particular sounds and is different from hyperacusis, another form of decreased sound tolerance, which is defined as a negative reaction to sound due to particular physical characteristics, like volume, type, and intensity.

Sound can propagate through a medium such as air, water and solids as longitudinal waves and also as a transverse wave in solids (see Longitudinal and transverse waves , below). (wikipedia.org)
Because less sound is absorbed in solids and liquids than in gases, sounds can propagate over much greater distances in these mediums. (britannica.com)
In addition to localized sound readings (i.e., sounds detected within the expected range of the hydrophones), SOSUS also picked up sounds channeled through specific conditions of state (i.e., pressure, temperature) or salinity that create channels though which sound waves propagate over long distances with minimal resistance and minimal loss of strength. (encyclopedia.com)
Sound waves can be trapped effectively in SOFAR channels and propagate with little loss of energy over distances in excess of 15,500 miles (25,0000 km). (encyclopedia.com)
In general, the speed of sound depends upon the medium through which the sound waves propagate and the properties of the medium (e.g., state, temperature, pressure, salinity, etc. (encyclopedia.com)
