• loud
  • 195 dB Hearing Loss Loud noises, infections, head injuries, brain damage, old age, and genetic diseases may cause people to lose some or all of their ability to hear. (prezi.com)
  • cochlear implant
  • For certain people with very severe hearing loss that is not improved by a simple hearing aid, a cochlear implant device may improve sound generation to the brain. (epnet.com)
  • Ultimately the affected person may bridge communication problems by becoming skilled in sign language, speech-reading, using a hearing aid, or accepting elective surgery to use a prosthetic devices such as a cochlear implant. (wikipedia.org)
  • They may have to adapt to using hearing aids or a cochlear implant, develop speech-reading skills, and/or learn sign language. (wikipedia.org)
  • noise
  • Age-related and noise-induced hearing losses in humans are multifactorial, with contributions from, and potential interactions among, numerous variables that can shape final outcome. (jneurosci.org)
  • Noise-induced hearing loss can be caused by outside (e.g. trains) or inside (e.g. music) noise. (wikipedia.org)
  • In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss. (wikipedia.org)
  • Although some presbycusis may occur naturally with age, in many developed nations the cumulative impact of noise is sufficient to impair the hearing of a large fraction of the population over the course of a lifetime. (wikipedia.org)
  • People with spatial hearing loss have difficulty processing speech that arrives from one direction while simultaneously filtering out 'noise' arriving from other directions. (wikipedia.org)
  • Through childhood and into adulthood it can be viewed as spatial hearing gain (with it becoming easier to hear speech in noise), and then with middle age and beyond the spatial hearing loss begins (with it becoming harder again to hear speech in noise). (wikipedia.org)
  • The U.S. Environmental Protection Agency has asserted the same sentiment and testified before the U.S. Congress that approximately 34 million Americans are exposed to noise pollution levels (mostly from roadway and aircraft noise) that expose humans to noise health effects including the risk of hearing loss (EPA, 1972).

  • One of the most common causes is noise-induced hearing loss. (wikipedia.org)
  • inner ear
  • Congenital malformations of the inner ear cause hearing loss in some adults. (mhmedical.com)
  • The mechanism of hearing loss can be attributed to aging, infection, surgery, prolonged use of some medications, trauma, and to stereocilia of the cochlea, the principal fluid filled structure of the inner ear. (wikipedia.org)
  • The elevated sound levels cause trauma to cochlear structure in the inner ear, which gives rise to irreversible hearing loss. (wikipedia.org)
  • Cochlea Snail-shaped structure in the inner ear that contains the organ of hearing. (wikipedia.org)
  • cause
  • In normal hearing, sound vibrations are funneled by the outer ear into the ear canal where they cause vibrations in the eardrum. (tinnitusformula.com)
  • Follow treatment plans that help manage health conditions that may cause hearing loss. (epnet.com)
  • The cause of presbycusis is a combination of genetics, cumulative environmental exposures and pathophysiological changes related to aging. (wikipedia.org)
  • In children hearing problems can affect the ability to learn spoken language and in adults it can cause work related difficulties. (wikipedia.org)
  • Certain infections during pregnancy such as syphilis and rubella may also cause hearing loss. (wikipedia.org)
  • For some kinds of hearing loss the cause may be classified as of unknown cause. (wikipedia.org)
  • Disturbances (such as stroke or trauma) at any of these levels can cause hearing problems, especially if the disturbance is bilateral. (wikipedia.org)

  • profoundly
  • It may provide partial hearing to the profoundly deaf. (epnet.com)
  • Audiologists are primarily concerned with hearing loss that occurs within the speech banana because it can slow the development of a child's language and speech abilities, and this in turn can profoundly interfere with learning. (wikipedia.org)
  • spoken
  • Captioning Text display of spoken words, presented on a television or a movie screen, that allows a deaf or hard-of-hearing viewer to follow the dialogue and the action of a program simultaneously. (wikipedia.org)
  • frequency
  • They found that the children with ASD had hearing difficultly in a specific frequency (1-2 kHz) that is important for processing speech. (medindia.net)
  • If these pressure waves are strong enough and within the audible frequency spectrum, a sensation of hearing is produced. (wikipedia.org)
  • Some of those with spatial hearing loss are unable to process ITD (low frequency) cues. (wikipedia.org)
  • Human hearing extends in frequency from 20-20,000 Hz, and in amplitude from 0 dB to 130 dB or more. (wikipedia.org)
  • There are many qualities of human hearing besides frequency range and amplitude that can't easily be measured quantitatively. (wikipedia.org)
