ABSTRACT
In recent years, huge progress has been made in the design and operation of cochlear implants. The published literature notes that the quality of sound perception among cochlear implant users is severely limited. Usually, patients experience difficulties in difficult situations, such as speech perception in noisy environments or in a situation with several speakers. There are many factors, both technical and physiological, that complicate auditory perception in patients with cochlear implants. The main characteristics of auditory perception are the height and volume of perceived sounds. This article presents an analysis of the literature data on the features of auditory perception in patients with cochlear implants (CI). Existing studies show that the sound quality of CI users is limited primarily by pitch distortion and dynamic range compression. The most important characteristic of auditory perception is the frequency differential threshold, which is within two semitones, while participants with normal hearing detect a difference of one semitone. Low frequency resolution determines low speech intelligibility. New research should be aimed at developing promising methods to improve the quality of sound perception among CI users.
