The theory was proposed by Ernest Wever and Charles Bray in 1930 as a supplement to the frequency theory of hearing. It was later discovered that this only occurs in response to sounds that are about 500 Hz to 5000 Hz. Volley Theory of Hearing demonstrated by four neurons firing at a phase-locked frequency to the sound stimulus.
Place theory. 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 ...
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 described by the volley theory. Temporal theory competes with the place theory of hearing, which instead states that pitch is signaled according to the locations of vibrations along the basilar membrane.
E. Glen Wever. Ernest Glen Wever (October 16, 1902–September 4, 1991) was an American experimental psychologist known for his elucidation of hearing in vertebrates, ranging from the biomechanical functioning of the cochlea to the neural coding of sound and the evolutionary biology of hearing.

Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
Harrison Butker’s commencement speech left some at Benedictine College outraged after the Kansas City Chiefs kicker encouraged women to become homemakers.
Absolute threshold of hearing. The absolute threshold of hearing ( ATH ), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the ...
J. Robert Oppenheimer (born Julius Robert Oppenheimer; / ˈɒpənhaɪmər / OP-ən-hy-mər; April 22, 1904 – February 18, 1967) was an American theoretical physicist. He was director of the Manhattan Project 's Los Alamos Laboratory during World War II and is often called the "father of the atomic bomb ". Born in New York City, Oppenheimer ...
