However, even smaller pitch differences can be perceived through other means. For example, the interference of two pitches can often be heard as a repetitive variation in the volume of the tone. This amplitude modulation occurs with a frequency equal to the difference in frequencies of the two tones and is known as beating .
In the physical sense of the term, the word "pitch" refers to the frequency of a sound. Another term that is frequently used by music neuroscientists is "fine-grained pitch processing" which refers to the ability of a person to distinguish minor changes or fluctuations in pitch. Processing pitch is an extremely integral part of music cognition.
[7] If two sounds, A and B, are rapidly alternated in time, after a few seconds the perception may seem to "split" so that the listener hears two rather than one stream of sound, each stream corresponding to the repetitions of one of the two sounds, for example, A-A-A-A-, etc. accompanied by B-B-B-B-, etc. The tendency towards segregation into ...
Xylorimba, range C3-C8 The xylorimba (sometimes referred to as xylo-marimba or marimba-xylophone ) is a pitched percussion instrument similar to an extended-range xylophone with a range identical to some 5-octave celestas or 5-octave marimbas , though typically an octave higher than the latter.
Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues.These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people.

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 ...
Pitch is an assigned, perceptual property where a listener orders sound frequencies from low to high. Pitch is hypothesized to be determined by receiving phase-locked input from neuronal axons and combining that information into harmonics. In simple sounds consisting of one frequency, the pitch is equivalent to the frequency.
To produce sounds that people can interpret as spoken words, the movement of air must pass through the vocal folds, up through the throat and, into the mouth or nose to then leave the body. Different sounds are formed by different positions of the mouth—or, as linguists call it, "the oral cavity" (to distinguish it from the nasal cavity).
