The social model of deafness stems from the social model of disability. The concept of social disability was created by people who are disabled themselves, their families, friends, and associated social and political networks. Professionals in the human services fields and the social sciences greatly contributed to the social model. This model ...
TRACE is a connectionist model of speech perception, proposed by James McClelland and Jeffrey Elman in 1986. [1] It is based on a structure called "the TRACE", a dynamic processing structure made up of a network of units, which performs as the system's working memory as well as the perceptual processing mechanism.

Nonsyndromic deafness constitutes 75% of all hearing loss cases, and an estimated 100 genes are thought to be linked to this condition. About 80% are linked to autosomal recessive inheritance, 15% to autosomal dominant inheritance, 1-3% through the X chromosome, and 0.5-1% are associated with mitochondrial inheritance. [1] [2]
Cerebral deafness (also known as cortical deafness or central deafness) is a disorder characterized by complete deafness that is the result of damage to the central nervous system. The primary distinction between auditory agnosia and cerebral deafness is the ability to detect pure tones, as measured with pure tone audiometry.
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
where F is the center frequency of the filter, in kHz, and ERB( F) is the bandwidth of the filter in Hz. The approximation is based on the results of a number of published simultaneous masking experiments and is valid from 0.1– 6 500 Hz. [1] Seven years later, Glasberg & Moore (1990) published another, simpler approximation: [2]
A family of metrics for speech intelligibility, [263] speech quality, [267] [268] and music quality [269] has been derived using a shared model of the auditory periphery [270] that can represent hearing loss. Using a model of the impaired periphery leads to more accurate predictions for hearing-impaired listeners than using a normal-hearing ...
DOG activates 2, and inhibits 1 letters in FOG. – +2 DOG activates 1, and inhibits 2 letters in D AN. – +1 The consistency of this model to agnosia is shown by evidence that bilateral lesions to the superior temporal sulcus produces 'pure word deafness' (Kussmaul, 1877), or as it is understood today, speech agnosia.
