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 ...
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 ...
Change deafness is a perceptual phenomenon that occurs when, under certain circumstances, a physical change in an auditory stimulus goes unnoticed by the listener. There is uncertainty regarding the mechanisms by which changes to auditory stimuli go undetected, though scientific research has been done to determine the levels of processing at which these consciously undetected auditory changes ...
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.
The perception of auditory signals came as a nervous impulse from the inner ear to the cochlear nuclei of the brainstem, [11] which is the first relay station. In an ascending pathway, various acoustic reflexes and sound localisation are regulated via relay stations.
Y 1 = X 1 LFM, and Y 2 = X 2 HM, where L is the transfer function of the loudspeaker in the free field, F is the HRTF, M is the microphone transfer function, and H is the headphone-to-eardrum transfer function. Setting Y 1 = Y 2, and solving for X 2 yields X 2 = X 1 LF/H. By observation, the desired transfer function is T= LF/H.
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]
The two-streams hypothesis is a model of the neural processing of vision as well as hearing. [1] The hypothesis, given its initial characterisation in a paper by David Milner and Melvyn A. Goodale in 1992, argues that humans possess two distinct visual systems. [2] Recently there seems to be evidence of two distinct auditory systems as well.
