What is a critique of the place theory of sound perception? Place theory only works well for sounds above 4000 Hz . ... Kathy stimulates the auditory nerve of rodents exposed to loud noise and records the activity of neurons in the primary and secondary cortices.
What is the correct explanation of the place theory of hearing?
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 the problem with place theory?
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.
Which is correct place theory or frequency theory?
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.
Is the place 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 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 .
How does place theory explain how we hear sound what is the problem with this 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 . 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.
Which areas of the brain are involved with hearing?
The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching.
What two phenomena are not explained by the place theory?
What two phenomena are not explained by the place theory? Hearing the missing fundamental of a complex sound and to account for perceptual differences in low-frequency stimulation where the tuning curves are rather wide .
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 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 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.
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 the difference between place and temporal theory?
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.
Who discovered theory of hearing?
Rinne (1865) and Rutherford (1880) proposed the early forms of the Frequency theory of hearing. Their theories were known as telephone theories due to the similarity between the waveform of speech sound in a telephone line and the incoming sound signal to the human brain.
Where is the first place that information from both ears is combined?
Way Stations in the Brain
Impulses from each ear are transmitted to the nucleus on both the opposite and the same side of the head. The laminar nucleus is, therefore, the first place where the information from both ears comes together in one place.
