If one ear has normal thresholds while the other has sensorineural hearing loss (SNHL), diplacusis may be present, as much as 15–20% (for example 200 Hz one ear => 240 Hz in the other). [citation needed] The pitch may be difficult to match because the SNHL ear hears the sound "fuzzy". Bilateral SNHL gives less diplacusis, but pitch ...
Congenital deafness or sensorineural hearing loss is an often used model for the study of the inner ear regarding pitch perception and theories of hearing in general. Frequency analysis of these individuals’ hearing has given insight on common deviations from normal tuning curves, [13] excitation patterns, and frequency discrimination ranges ...
In his early career in the 1970s, Moore was mainly interested in fundamental research on loudness and pitch perception, masking effects, and speech recognition. [4] He started to consider the practical aspects and potential applications of this research in the 1980s with his work on a 2-channel compression hearing aid. [4]
Place theory is a theory of hearing that states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane.By this theory, the pitch of a sound, such as a human voice or a musical tone, is determined by the places where the membrane vibrates, based on frequencies corresponding to the tonotopic organization of the primary auditory neurons.
Temporal envelope (ENV) and temporal fine structure (TFS) are changes in the amplitude and frequency of sound perceived by humans over time. These temporal changes are responsible for several aspects of auditory perception, including loudness, pitch and timbre perception and spatial hearing.

The temporal theory of hearing, also called frequency theory or timing theory, states that human perception of sound depends on temporal patterns with which neurons respond to sound in the cochlea. Therefore, in this theory, the pitch of a pure tone is determined by the period of neuron firing patterns—either of single neurons, or groups as ...
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.
