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.
Is frequency theory or place theory correct?
Is the frequency theory correct? 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 does frequency theory mean?
a late 19th-century theory specifying that pitch is coded by the rate at which action potentials are generated by auditory neurons within the basilar membrane of the ear.
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 the frequency volley theory?
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.
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. You may also read,
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. Check the answer of
How does place theory explain pitch?
The place theory of pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies. More specifically, the base of the basilar membrane responds best to high frequencies and the tip of the basilar membrane responds best to low frequencies.
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.

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. … A low frequency tone causes slow waves of motion in the basilar membrane and that might give rise to low firing rates in the auditory nerve.
Which theory of hearing is correct?
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.
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 frequency theory quizlet?
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. Sound waves cause the entire basilar membrane to vibrate at different rates, which causes the neural impulses to be transmitted at different rates.
Why can't volley theory explain all frequencies?
In general, it claimed that all sounds were encoded to the brain by neurons firing at a rate that mimics the frequency of the sound. … Through more research, it was determined that because phase synchrony is only accurate up to about 1000 Hz, volley theory cannot account for all frequencies at which we hear.
What are the two theories of pitch perception?
Two theories explain how people distinguish the pitch of different sounds: place theory and frequency theory.
What is frequency tuning curve?
a graph of neuronal response (usually measured in action potentials or spikes per unit time) as a function of a continuous stimulus attribute, such as orientation, wavelength, or frequency. PTCs bear a strong resemblance to the actual tuning curves measured in auditory nerve fibers. …
