• tinnitus
  • Noise at play is unregulated, and with sound levels in the average nightclub exceeding 100 decibels, you get your daily noise dose (accompanied by a bad dose of tinnitus - "ringing in the ears") in less than half an hour. (lovemusicpass.org)
  • Besides feeling fullness and muffled hearing, you might also experience popping, pain or tinnitus (ringing in the ears), or have difficulty maintaining balance. (aarp.org)
  • Patients may experience tinnitus in one or both ears or in the head. (encyclopedia.com)
  • In addition to informing how hearing tests are conducted, Auerbach suggests this compensation might be causing or contributing to other auditory perceptual disorders such as tinnitus, often described as a ringing in the ears, or hyperacusis, a condition that causes moderate, everyday sounds to be perceived as intolerably loud. (buffalo.edu)
  • Tinnitus retraining therapy (TRT) is a form of habituation therapy designed to help people who suffer from tinnitus, a ringing, buzzing, hissing, or other sound in the ears when no external sound is present. (wikipedia.org)
  • It has been proposed that tinnitus is caused by mechanisms that generate abnormal neural activity, specifically one mechanism called discordant damage (dysfunction) of outer and inner hair cells of the cochlea. (wikipedia.org)
  • The patient is taught the basic knowledge about the auditory system and its function, the mechanism of tinnitus generation and the annoyance associated with tinnitus. (wikipedia.org)
  • frequency
  • How does the ear amplify sounds of lower frequency? (brainscape.com)
  • Stellate (chopper) cells encode sound spectra (peaks and valleys) by spatial neural firing rates based on auditory input strength (rather than frequency). (wikipedia.org)
  • A very loud sound in a particular frequency range can damage the cochlea's hair cells that respond to that range, thereby reducing the ear's ability to hear those frequencies in the future, however, loud noise in any frequency range has deleterious effects across the entire range of human hearing. (wikipedia.org)
  • Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. (wikipedia.org)
  • sensory
  • The retina contains several layers of cells, but the actual sensory work is done by two kinds of photoreceptor cells in the deepest layer. (dana.org)
  • It is affected by the closing mechanism of the mechanical sensory ion channels at the tips of the hair bundles. (wikipedia.org)
  • The auditory system is the sensory system for the sense of hearing. (wikipedia.org)
  • It includes both the sensory organs (the ears) and the auditory parts of the sensory system. (wikipedia.org)
  • Hearing
  • The more a person's outer hair cells are damaged, the higher the hearing aid is turned on. (kidshealth.org)
  • Most people with hearing loss in both ears (called bilateral hearing loss) wear two hearing aids. (kidshealth.org)
  • Hearing aids process and amplify the speech or sound waves. (bloggingfusion.com)
  • Damaged hair cells are unable to trigger electrical signals to the brain, impeding hearing. (healthyhearing.com)
  • As you age - especially if you've been exposed to frequent loud noises - you might have presbycusis, a type of gradual hearing loss caused by the death of hair cells in the cochlea, in your inner ear. (aarp.org)
  • The inner part of the ear I responsible for hearing and equilibrium through the receptor cells found in it. (wordpress.com)
  • Hearing originates from pressure waves hitting auditory canal which ends when the brain perceives it. (wordpress.com)
  • Damage to these hair cells results in decreased hearing sensitivity, and because the inner ear hair cells cannot regenerate, this damage is permanent. (wikipedia.org)
  • While hearing sensitivity of mammals is similar to that of other classes of vertebrates, without functioning outer hair cells, the sensitivity decreases by approximately 50 dB[citation needed]. (wikipedia.org)
  • Outer hair cells extend the hearing range to about 200 kHz in some marine mammals. (wikipedia.org)
  • It turns out that the central auditory system can compensate for significant damage to the inner ear by turning up its volume control, partially overcoming the deficiency, explains lead author Richard Salvi, SUNY Distinguished Professor of Communicative Disorders and Sciences and director of UB's Center for Hearing and Deafness. (buffalo.edu)
  • A car won't run well if you remove half of those spark plugs, but people can still present with normal hearing thresholds if they've lost half or even three-quarters of their inner hair cells. (buffalo.edu)
  • Individual hearing range varies according to the general condition of a human's ears and nervous system. (wikipedia.org)
  • Hearing loss may occur in one or both ears. (wikipedia.org)
  • the hearing aid is able to sufficiently amplify sound to account for the attenuation caused by the conductive component. (wikipedia.org)
  • sounds
  • The effect of this system is to non-linearly amplify quiet sounds more than large ones so that a wide range of sound pressures can be reduced to a much smaller range of hair displacements. (wikipedia.org)
  • However, no such time or level differences exist for sounds originating along the circumference of circular conical slices, where the cone's axis lies along the line between the two ears. (wikipedia.org)
  • system
  • Your brain has a similar noise-cancellation system that works by comparing the mixture of sound reaching the two ears, cancelling some of the noise and leaving the signal more audible. (lovemusicpass.org)
  • The auditory system transforms mechanical energy-sound waves-into nerve impulses. (dana.org)
  • Hair cells within the cochlea are the receptors of the auditory system. (dana.org)
  • The system of human auditory allows the body to interpret and collect sound waves into meaningful messages. (wordpress.com)
  • Since CASA serves to model functionality parts of the auditory system, it is necessary to view parts of the biological auditory system in terms of known physical models. (wikipedia.org)
  • The auditory system uses several cues for sound source localization, including time- and level-differences (or intensity-difference) between both ears, spectral information, timing analysis, correlation analysis, and pattern matching. (wikipedia.org)
  • hairs
  • Outside the aircraft (not recommended) jet noise can reach an ear-thumping 120 decibels, literally enough to shake the hairs off your hair cells. (lovemusicpass.org)
  • perception
  • Important model of pitch perception by unifying 2 schools of pitch theory: Place theories (emphasizing the role of resolved harmonics) Temporal theories (emphasizing the role of unresolved harmonics) The correlogram is generally computed in the time domain by autocorrelating the simulated auditory nerve firing activity to the output of each filter channel. (wikipedia.org)
  • Auditory perception Ability to identify, interpret, and attach meaning to sound. (wikipedia.org)
  • fluid
  • They derive their name from the tufts of stereocilia called hair bundles that protrude from the apical surface of the cell into the fluid-filled cochlear duct. (wikipedia.org)
  • receptor
  • Instead, the influx of positive ions from the endolymph in the scala media depolarizes the cell, resulting in a receptor potential. (wikipedia.org)
  • membrane
  • The quickness of the hair cell response may also be due to the fact that it can increase the amount of neurotransmitter release in response to a change as little as 100 μV in membrane potential. (wikipedia.org)
  • binaural
  • It may also refer to the methods in acoustical engineering to simulate the placement of an auditory cue in a virtual 3D space (see binaural recording, wave field synthesis). (wikipedia.org)
