Rather than embrace the view that deafness is a "personal tragedy", the Deaf community contrasts the medical model of deafness by seeing all aspects of the deaf experience as positive. The birth of a deaf child is seen as a cause for celebration. [3] Deaf people point to the perspective on child rearing they share with hearing people.
In other words, the components of the complex tone C consisted only of Cs, but in different octaves, and the components of the complex tone F ♯ consisted only of F ♯ s, but in different octaves. [2] When such complex tones are played in semitone steps the listener perceives a scale that appears to ascend endlessly in pitch.
Each Shepard tone consists of a set of octave-related sinusoids, whose amplitudes are scaled by a fixed bell-shaped spectral envelope based on a log frequency scale. For example, one tone might consist of a sinusoid at 440 Hz, accompanied by sinusoid at the higher octaves (880 Hz, 1760 Hz, etc.) and lower octaves (220 Hz, 110 Hz, etc.).
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 ...
Amusia is a musical disorder that appears mainly as a defect in processing pitch but also encompasses musical memory and recognition. [1] Two main classifications of amusia exist: acquired amusia, which occurs as a result of brain damage, and congenital amusia, which results from a music-processing anomaly present since birth.
Lichtheim [11] (1885) proposed that auditory agnosia is the result of damage to a brain area dedicated to the perception of spoken words, and consequently renamed this disorder from 'word deafness' to 'pure word deafness'. The description of word deafness as being exclusively for words was adopted by the scientific community despite the patient ...
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.
Right-handers and left-handers differ statistically in how the scale illusion is perceived. The effect was discovered by Diana Deutsch in 1973. In a clinical study, patients with hemispatial neglect were shown to experience the scale illusion. Further, in an MEG study on normal listeners the scale illusion was found to be neurally represented ...
