The ear-brain system is a complex instrument. Currently there are
two overlapping theories
of how we hear; the place theory
What are theories of hearing?
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
What are the 2 theories of pitch detection?
Several theories have been proposed to account for pitch perception. We’ll discuss two of them here:
temporal theory and place theory
What is frequency theory of hearing?
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
Are place theory and frequency theory the same?
What is the difference between place theory and frequency theory quizlet? Place theory states that the
perception of pitch depends
on what area of the basilar membrane
Which will you hear as the highest pitch?
For a person with normal hearing, when it comes to pitch the human hearing range
Is Place theory or frequency theory more accurate?
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 normal range of human hearing?
Humans can detect sounds in a frequency range from
about 20 Hz to 20 kHz
. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
What is hearing called psychology?
n. the ability of an organism to sense sound and to process and interpret the sensations to gain information about the source and nature of the sound. In humans, hearing refers to the perception of sound. Also called
audition
.
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.
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
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
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 is the highest pitch a human can sing?
Consequently, singing voices for women are usually a little higher than for men, with the highest female voice (soprano) reaching
C6
and the lowest one (contralto) going down to E3, while the highest male voice (countertenor, typically in falsetto) may hit E5, and the lowest one (bass) can drop down to E2.
What frequency can humans hear by age?
People of All ages without a hearing impairment should be able to hear the
8000hz
. People under 50 should be able to hear the 12,000hz and people under 40, the 15,000hz. Under 30s should hear the 16,000hz, and the 17,000hz is receivable for those under 24. MORE: Test!
How many DB can a human hear?
What is sound? Humans can hear sounds
between 0 and 140 decibels
.
