1. The Place Theory of Pitch Perception - HyperPhysics Concepts
The place theory is the first step toward an understanding of pitch perception. But considering the extreme pitch sensitivity of the human ear, it is thought ...
Since it seems unlikely that the basic place theory for pitch perception can explain the extraordinary pitch resolution of the human ear, some sharpening mechanism must be operating. Several of the proposed mechanism have the nature of lateral inhibition on the basilar membrane. One way to sharpen the pitch perception would be bring the peak of the excitation pattern on the basilar membrane into greater relief by inhibiting the firing of those hair cells which are adjacent to the peak. Since nerve cells obey an "all-or-none" law, discharging when receiving the appropriate stimulus and then drawing energy from the metabolism to recharge before firing again, one form the lateral inhibition could take is the inhibition of the recharging process since the cells at the peak of the response will be drawing energy from the surrounding fluid most rapidly. Inhibition of the lateral hair cells could also occur at the ganglia, with some kind of inhibitory gating which lets through only those pulses from the cells which are firing most rapidly. It is known that there are feedback signals from the brain to the hair cells, so the inhibition could occur by that means.

The ability to locate sound in our environments is an important part of hearing. Localizing sound could be considered similar to the way that we perceive depth in our visual fields. Like the monocular and binocular cues that provided information about depth, the auditory system uses both monaural (one-eared) and binaural (two-eared) cues to localize sound.

Pitch is a fundamental aspect of auditory perception that plays an important role in our ability to understand speech, appreciate music, and attend to one sound while ignoring others. The questions surrounding how pitch is represented in the auditory system, and how our percept relates to the underlying acoustic waveform, have been a topic of inquiry and debate for well over a century. New findings and technological innovations have led to challenges of some long-standing assumptions and have raised new questions. This article reviews some recent developments in the study of pitch coding and perception and focuses on the topic of how pitch information is extracted from peripheral representations based on frequency-to-place mapping (tonotopy), stimulus-driven auditory-nerve spike timing (phase locking), or a combination of both. Although a definitive resolution has proved elusive, the answers to these questions have potentially important implications for mitigating the effects of hearing loss via devices such as cochlear implants.

FAQs
What Does The Place Theory Of Pitch Perception Suggest? ›
The place theory of pitch perception suggests that different portions of the
The place theory of hearing proposes that different areas of the cochlea respond to different frequencies. Higher tones excite areas closest to the opening of the cochlea (near the oval window). Lower tones excite areas near the narrow tip of the cochlea, at the opposite end.
What is the place theory of pitch AP Psychology? ›The place theory explains how we hear high-pitched sounds. Developed by Georg von Bekesy, it links pitch with the location of the basilar membrane, and it is stimulated because certain hair cells are attuned to certain pitches.
What is the problem with the place theory of pitch perception? ›The biggest problem of the place theory is that it fails to identify the pitch of a stimulus with missing fundamental. According to Helmholtz's theory, it is impossible to perceive a pitch when there is no spectral peak at the position along the basilar membrane which corresponds to the frequency of the pitch.
What are the three theories of pitch perception? ›We'll briefly discuss three of them here: temporal theory, volley theory and place theory. The temporal theory of pitch perception asserts that frequency is coded by the activity level of a sensory neuron and that the firing rate of cilia or groups of cilia encode constant pitch perception.
Who proposed place theory of pitch perception? ›A theory of pitch perception first proposed in 1865 by the German physiologist, physicist, and mathematician Hermann Ludwig Ferdinand von Helmholtz (1821–94) according to which the perceived pitch of a tone depends on the position or place on the basilar membrane of the auditory receptors that transmit nerve impulses.
What is the place theory and the frequency theory of sound perception? ›Most psychologists agree that hearing sound stimuli at low frequencies is accounted to the frequency theory, whereas those at high frequencies are attributed to the place principle. Sound stimuli in mid frequencies are believed to be rightfully accounted to both hearing theories.
What is the place theory psych quizlet? ›According to the place theory of hearing, we can hear different pitches due to specific sound frequencies causing vibrations in specific parts on the basilar membrane of the cochlea. In other words, different parts of the cochlea are activated by different frequencies.
What is pitch and what are the two major theories on how pitch is perceived? ›There are two broad categories of pitch-perception models: place or spectral models consider that pitch is mainly related to the Fourier spectrum of the stimulus, whereas for periodicity or temporal models its characteristics in the time domain are more important.
What determines the pitch in psychology? ›Pitch is essentially the perceptual correlate of waveform periodicity, or repetition rate: The faster a waveform repeats over time, the higher its perceived pitch is.
What does place theory explain? ›
According to place theory, the hair cells and nerve fibers of the cochlea are divided into different regions that detect specific sound frequencies. The areas which are closest to the opening of the cochlea respond to higher tones, while the areas at the opposite end of the cochlea respond to lower tones.
How does place theory explain how we hear quizlet? ›Place theory proposes that our brain interprets a particular pitch by decoding the place where a sound wave stimulates the cochlea's basilar membrane. Frequency theory proposes that the brain deciphers the frequency of the neural impulses traveling up the auditory nerve to the brain.
What is the place code of hearing? ›The first potential code, known as the place code, reflects the mechanical filtering that takes place in the cochlea of the inner ear. The basilar membrane, which runs the length of the fluid-filled cochlea from the base to the apex, vibrates in response to sound.
What do the place theory and the frequency theory help to explain quizlet? ›Place theory accounts for the perception of high-frequency sounds; frequency theory explains our perception of low-frequency sounds.
