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 ...
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 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.
Psychoacoustic model. Psychoacoustics has long enjoyed a symbiotic relationship with computer science. Internet pioneers J. C. R. Licklider and Bob Taylor both completed graduate-level work in psychoacoustics, while BBN Technologies originally specialized in consulting on acoustics issues before it began building the first packet-switched network.
It is typically experienced as a secondary symptom of sensorineural hearing loss, although not all patients with sensorineural hearing loss experience diplacusis or tinnitus. [ 1 ] [ 2 ] The onset is usually spontaneous and can occur following an acoustic trauma , for example an explosive noise, or in the presence of an ear infection . [ 3 ]
Change deafness – Change deafness is the concept of change blindness for auditory information. [51] In his experiment, Vitevitch (2003) used a speech shadowing task to demonstrate change deafness. [52] He presented a list of words to participants and had them simultaneously repeat the words they heard.
A report on proposed changes to U.S. dietary guidelines suggests encouraging Americans to eat more beans and lentils for protein and less red meat.
Sensory substitution is a change of the characteristics of one sensory modality into stimuli of another sensory modality.. A sensory substitution system consists of three parts: a sensor, a coupling system, and a stimulator.
