Auditory dyssynchrony Health Dictionary

See VESTIBULOCOCHLEAR NERVE.... auditory nerve

adj. relating to the ear or to the sense of hearing.... auditory

a device similar to a *cochlear implant except that the electrode stimulates the auditory parts of the *brainstem rather than the cochlea. It is used to restore hearing of profoundly deaf people who have had damage to both auditory nerves and are hence unsuitable for cochlear implantation. It consists of an electrode that is permanently implanted on the surface of the brainstem. An external device with a microphone and an electronic processing unit pass information to the electrode using radio-frequency waves. The implant is powered by batteries in the external part of the device. It is most commonly used in patients with *neurofibromatosis type II who have had bilateral *vestibular schwannomas.... auditory brainstem implant

(ABR audiometry, brainstem evoked response audiometry, BSER) an objective test of hearing that measures the electrical activity in the auditory nerve and *brainstem following sound stimulation using repeated clicks or brief tones.... auditory brainstem response audiometry

(auditory meatus) the canal leading from the pinna to the eardrum.... auditory canal

(auditory neuropathy, auditory dyssynchrony) a form of hearing loss characterized by normal cochlear function as measured by *otoacoustic emissions or detection of *cochlear microphonics but abnormal or absent *middle ear reflexes and abnormal *auditory brainstem responses.... auditory neuropathy spectrum disorder

(APD, central auditory processing disorder, CAPD) a series of conditions characterized by difficulty in hearing and processing auditory information, especially in poor acoustic environments, despite normal or near-normal ear function. It may be due to genetic factors, maturational delay in the central nervous system, or focal abnormalities of the central nervous system (such as tumours). Treatments include *hearing therapy, *auditory skills training, educational support, use of *assistive listening devices, and training with computerized therapy tools.... auditory processing disorder

a method of teaching people to use their hearing to its best potential, undertaken in the treatment of *auditory processing disorder.... auditory skills training

(ASSR) an objective test of hearing that measures the electrical activity in the auditory nerve and *brainstem following sound stimulation using a modulated continuous tone.... auditory steady state response

(AVT) a technique for teaching deaf children to communicate that focuses on speech and residual hearing rather than sign language.... auditory verbal therapy

see auditory processing disorder.... central auditory processing disorder

(CHAPS) a questionnaire designed to assess children’s hearing abilities in certain situations. It is used in the diagnosis of *auditory processing disorder.... children’s auditory performance scale

(OAD, King–Kopetzky syndrome) hearing difficulty, especially in noisy environments, in an individual with a normal *audiogram: a form of *auditory processing disorder. Treatment includes *hearing therapy.... obscure auditory dysfunction
