What does place theory not account for?
Place theory of hearing is unable to account for sounds with very low frequencies, such as those in bass notes, due to the fact that there are no auditory nerve fibers that have a preference for very low frequencies.
What is the major flaw in the frequency theory of pitch perception?
The major flaw in frequency theory is that the neurons fire at a maximum of about 1,000 impulses per second, so frequency theory would not account for sounds above 1,000 hertz. This means that Martin would not be able to hear the high notes of his favorite song!
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.
Does Place explain pitch perception?
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 that there must be some additional “sharpening” mechanism to enhance the pitch resolution.
Why can neither place theory nor frequency theory independently explain human perception of pitch?
The typical score; how spread out the scores are. Why can neither place theory nor frequency theory individually explain human perception of pitch? Hair cells cannot generate firing rates to match high frequencies.
Is place theory of frequency theory correct?
Place theory is accurate, except that receptive cells along the inner membrane lack independence in response. They vibrate together as suggested by the frequency theory. Sound waves travel along the membrane, peaking at a given region depending on the frequency.
What is the difference between the temporal theory and the place theory of pitch?
Two rival theories have slugged it out over the years: ‘place theory’, in which pitch is determined by which neurons are active, and ‘temporal theory’, in which pitch is determined by how the neurons are active, specifically in terms of their temporal firing patterns.
How does the frequency theory suggest an alternative to the explanation of how we discriminate pitch?
How does the frequency theory suggest an alternative to the explanation of how we discriminate pitch? The brain reads pitch by monitoring the frequency of neural impulses traveling up the auditory nerve. What are the four basic sensations skin can detect? Pressure, warmth, cold, pain.
What determines our perception of pitch?
The wavelength of the sound wave (known as frequency) is measured in terms of the number of waves that arrive per second and determines our perception of pitch, the perceived frequency of a sound.
Which theory best explains human perception of low pitch tones?
Frequency theory best explains how we sense low pitches.
On which component of the ear does the place theory of pitch perception focus?
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.
How does the place theory explain how we discriminate pitch quizlet?
How does von Helmholtz’s place theory explain how we discriminate pitch? We hear different pitches because different sound waves trigger activity at different places along the cochlea’s basilar membrane. So, the brain determines a sound’s pitch by recognizing the specific place that is generating the neural signal.
What are the two theories of pitch perception?
How do we discriminate pitch?
In the context of pitch discrimination, a thresholding procedure involves manipulating the pitch interval between paired stimuli to determine the minimum interval (i.e. least amount of difference in pitch) for which a participant can reliably detect the presence of a difference in pitch between the paired tones.
How does frequency theory suggest an alternative to how we discriminate pitch?
What is pitch theory in psychology?
The temporal theory of pitch perception asserts that frequency is coded by the activity level of a sensory neuron. This would mean that a given hair cell would fire action potentials related to the frequency of the sound wave.
What is the place theory of pitch perception?
The Place Theory of Pitch Perception Place Theory High frequency sounds selectively vibrate the basilar membraneof the inner earnear the entrance port (the oval window). Lower frequencies travel further along the membrane before causing appreciable excitation of the membrane.
What is the basic pitch determining mechanism?
The basic pitchdetermining mechanism is based on the location along the membrane where the hair cellsare stimulated. A schematic view of the place theory unrolls the cochleaand represents the distribution of sensitive hair cells on the organ of Corti.
What is the importance of place theory in singing?
The place theory is the first step toward an understanding of pitch perception. But considering the extreme pitch sensitivityof the human ear, it is thought that there must be some additional “sharpening” mechanism to enhance the pitch resolution. Role of place theory in distinguishing vocal sounds
Who came up with the place theory?
The place theory is usually attributed to Hermann Helmholtz, though it was widely believed much earlier.
