Place theory states that the perception of pitch is associated with vibration of different portions of the basilar membrane
Is place theory or frequency theory more accurate?
Frequency Theory (Rutherford, 1886) holds that pitch perception corresponds to the rate of vibration of all receptive cells along the inner ear membrane. ... Place theory is accurate , except that receptive cells along the inner membrane lack independence in response.
What is the frequency theory?
Quick Reference. A theory of pitch perception first proposed in 1886 by the British physiologist William Rutherford (1839–99) according to which the ear converts acoustic vibrations into nerve impulses by emitting one impulse for each cycle of the sound wave in the manner of a telephone.
What is frequency theory in psychology?
The frequency theory of hearing proposes that whatever the pitch of a sound wave, nerve impulses of a corresponding frequency will be sent to the auditory nerve . For example, a tone measuring 600 hertz will be transduced into 600 nerve impulses a second.
What are the two theories of hearing?
The ear-brain system is a complex instrument. Currently there are two overlapping theories of how we hear; the place theory of hearing and the temporal theory of hearing .
Why is the frequency theory important?
This is attributed to the frequency theory of hearing. The frequency theory of hearing states that the frequency of the auditory nerve’s impulses corresponds to the frequency of a tone , which allows us to detect its pitch.
What does frequency theory best explain?
Frequency theory best explains how we sense low pitches . ... Touching adjacent cold and pressure spots triggers a sense of wetness, which you can experience by touching dry, cold metal.
What is an example of place theory?
The place theory of hearing is used to explain how we distinguish high-pitched sounds that possess a frequency that exceeds 5,000 hertz . ... For example, a sound that measures 6,000 hertz would stimulate the spot along the basilar membrane that possesses a characteristic frequency of 6,000 hertz.
Who proposed place theory?
The place theory is usually attributed to Hermann Helmholtz , though it was widely believed much earlier.
How loudness is detected?
Although loudness is directly determined by the number of hair cells that are vibrating , two different mechanisms are used to detect pitch. The frequency theory of hearing proposes that whatever the pitch of a sound wave, nerve impulses of a corresponding frequency will be sent to the auditory nerve.
What is pitch in psychology?
Pitch is a musical term that refers to the sound quality ; highness or lowness (frequency) of a sound or musical tone. All sounds have a measurable frequency, whether they are classified as music, sounds or noise and pitch refers to a sound’s place on the frequency scale of human hearing.
What is the volley principle in psychology?
the principle that individual fibers in an auditory nerve respond to one or another stimulus in a rapid succession of rhythmic sound stimuli , whereas other fibers in the nerve respond to the second, third, or nth stimulus.
How would you relate frequency and pitch?
The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. ... That is, two sound waves sound good when played together if one sound has twice the frequency of the other.
What is place coding theory?
The place code theory is given that name because it identifies each pitch with a particular place along the basilar membrane . It assumes that any excitation of that particular place gives rise to a specific pitch.
What are the theories of hearing in psychology?
There are several theories that attempt to explain the perceptual processing of sound sensation. However, the most referred to hearing theories are the Place Theory and the Frequency Theory . These are two opposing theories that have been continuously developed until mid-20th century.
Which theory of hearing explains how sounds up to 4000 hertz reach the brain?
How are higher and lower sounds detected? The frequency theoryof hearing states that as pitch rises, nerve impulses of the same frequency are fed into the auditory nerve. This explains how sounds up to about 4000 hertz reach the brain.
