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 ...
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 ]
Although pitch retrieval mechanisms in the auditory system are still a matter of debate, [76] [115] TFS n information may be used to retrieve the pitch of low-frequency pure tones [75] and estimate the individual frequencies of the low-numbered (ca. 1st-8th) harmonics of a complex sound, [116] frequencies from which the fundamental frequency of ...
Licklider wrote a paper entitled "A duplex theory of pitch perception". [16] Psychoacoustics is applied within many fields of software development, where developers map proven and experimental mathematical patterns in digital signal processing. Many audio compression codecs such as MP3 and Opus use a psychoacoustic model to increase compression ...
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]
His major contributions in psychoacoustics are in pitch perception, binaural hearing, and sound localization. Working with junior colleagues, he discovered several major pitch effects: the binaural edge pitch, [ 1 ] the binaural coherence edge pitch, [ 2 ] the pitch shifts of mistuned harmonics, [ 3 ] [ 4 ] and the harmonic unmasking effect.

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 ...
In the context of singing, it is important for singers to maintain pitch accuracy, even when they are drowned out by orchestral accompaniment or by fellow singers. Many studies have looked into the effects of both external auditory feedback and proprioception (also known as internal feedback) on pitch control. It has been found that external ...
