• SNHL
  • Sensori-neural (SNHL). (royalfree.nhs.uk)
  • SNHL accounts for about 90% of hearing loss reported. (wikipedia.org)
  • Frequent symptoms of SNHL are loss of acuity in distinguishing foreground voices against noisy backgrounds, difficulty understanding on the telephone, some kinds of sounds seeming excessively loud or shrill (recruitment), difficulty understanding some parts of speech (fricatives and sibilants), loss of directionality of sound (especially with high frequency sounds), perception that people mumble when speaking, and difficulty understanding speech.

  • Audiology
  • But section 3.1 does make it clear that CCGs should be familiar with their commissioning responsibilities in relation to hearing and wider audiology services and appendix 3 helpfully clarifies the responsibilities of CCGs, NHS England and PHE in the complex environment of commissioning the various parts of a child's audiology journey. (kidsaudiologist.info)
  • Hearing problems may be unrecognised or undiagnosed because behaviours associated with hearing loss may have been thought of as being part of the learning disability, or because local audiology services are not accessible to them. (kidsaudiologist.info)
  • Audiology - The science of hearing, including the evaluation of hearing impairments and the rehabilitation of people with hearing impairments. (helenacollege.edu)
  • Audiology , the study, assessment , prevention, and treatment of disorders of hearing and balance. (britannica.com)
  • Clinical audiology is concerned primarily with the assessment of the function of the human ear , which affects hearing sensitivity and balance. (britannica.com)
  • audiogram
  • An audiogram is a graph illustrating a person's usable hearing and the amount of hearing loss that an individual has for each ear. (medel.com)
  • Your audiogram is a 'picture' of your hearing. (medel.com)
  • Audiogram - A graph used to record the results of a hearing evaluation. (helenacollege.edu)
  • The conventional clinical audiogram plots hearing level with low dB values (normal hearing) at the top of the chart and raised levels (reduced hearing) closer to the abscissa. (britannica.com)
  • Therefore, raised hearing levels, representing decreased hearing, are plotted lower on the pure-tone audiogram chart. (britannica.com)
  • The reference baseline is called audiometric zero and represents the 0 dB hearing level line on the audiogram chart. (britannica.com)
  • Results of audiometric tests are used to diagnose hearing loss or diseases of the ear, and often make use of an audiogram. (wikipedia.org)
  • Cordia C. Bunch 1919 The concept of a frequency versus sensitivity (amplitude) audiogram plot of human hearing sensitivity was conceived by German physicist Max Wien in 1903. (wikipedia.org)
  • bilateral
  • Disturbances (such as stroke or trauma) at any of these levels can cause hearing problems, especially if the disturbance is bilateral. (wikipedia.org)
  • symptoms
  • For a detailed exposition of symptoms useful for screening, a self-assessment questionnaire was developed by the American Academy of Otolaryngology, called the Hearing Handicap Inventory for Adults (HHIA). (wikipedia.org)
  • frequencies
  • For clinical purposes, the hearing threshold is usually measured for single frequency tones at discrete frequencies from 500 Hz to 8,000 Hz, in octave or half-octave intervals, and reported in step sizes of 5 dB. (britannica.com)
  • The hearing loss is most marked at higher frequencies. (wikipedia.org)
  • The terms hearing impaired or hard of hearing are usually reserved for people who have relative insensitivity to sound in the speech frequencies. (wikipedia.org)
  • exposure
  • Exposure to a single, extreme noise (such as a nearby gunshot or explosion) can cause a sudden hearing loss referred to as acoustic trauma. (merckmanuals.com)
  • Exposure to a very loud noise such as a bomb blast can cause noise-induced hearing loss. (wikipedia.org)
  • Because of the cumulative impact of age and exposure to noise and other acoustic insults, 'typical' hearing may not be normative. (wikipedia.org)
  • Acoustic
  • Acoustic reflex and reflex decay tests are used to evaluate the integrity of a complicated neural network involving not only the auditory tracts to and through the brain stem but also. (oup.com)
  • Acoustic reflex and reflex decay tests are used to evaluate the integrity of a complicated neural network involving not only the auditory tracts to and through the brain stem but also decussating pathways in the brain stem and the course of CN VII to the innervation of the stapedius muscle. (oup.com)
  • degree
  • Doctors sometimes diagnose the degree of hearing. (reference.com)
  • It was not until 1922 that otolaryngologist Dr. Edmund P. Fowler, and physicists Dr. Harvey Fletcher and Robert Wegel of Western Electric Co. first employed frequency at octave intervals plotted along the abscissa and intensity downward along the ordinate as a degree of hearing loss. (wikipedia.org)
  • severity
  • The severity of a hearing loss is categorized according to the increase in volume above the usual level necessary before the listener can detect it. (wikipedia.org)
  • sound
  • The upper limit of hearing, where sound begins to become uncomfortably loud, is referred to as the threshold of discomfort (or uncomfortable loudness level). (britannica.com)
  • This abnormality prevents sound from being transmitted to the brain normally, which results in a hearing loss. (listenhearaudiology.com)
  • Hearing, or auditory perception, is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. (wikipedia.org)
  • Sound generators or hearing aids may help some. (wikipedia.org)
  • Deaf and Hard
  • Dual Party Relay - Three-way telephone access system linking Deaf and Hard of Hearing callers using an agent who has access to both parties. (helenacollege.edu)
  • clarification needed] Use of the terms "hearing impaired," "deaf-mute," or "deaf and dumb" to describe deaf and hard of hearing people is discouraged by advocacy organizations as they are offensive to many deaf and hard of hearing people. (wikipedia.org)
  • difficulties
  • The new framework is aimed at supporting NHS commissioners in ensuring they understand the importance of services for people with hearing loss and the potential impact of un-managed hearing and communication difficulties. (kidsaudiologist.info)
  • Unrecognised and unmanaged hearing loss can cause or contribute to speech or language delays, difficulties learning and reading, and cause difficulties communicating with others. (kidsaudiologist.info)
  • In children hearing problems can affect the ability to learn spoken language and in adults it can cause work related difficulties. (wikipedia.org)
