Describe the two main ways by which sound frequency is encoded at the level of the cochlea.
Solutions
Expert Solution
The cochlea in the ear is capable of analysis of sound in an exceptional way . Human cochlea allows the the frequency range between 20 Hz and 20,000 Hz perception .
Ways by which the cochlea encodes sound frequency:
1.Resonance:
Along the basilar membrane of cochlea, there are resonators which are tuned to different audible frequencies. There are fibers which are stretched on these basilar membranes like piano. This system of frequency tuned oscillators which are regulated by central nervous system.
2. Travelling wave :
When cochlea is stimulated by a sound wave ,there is motion in basilar membrane of cochlea that travelled from base of cochlea.
The wave amplitude increased with the distance travelled then there was a rapid drop after reaching the maximal point. The point of maximal amplitude depends upon the sound frequency.
- Higher sounds had maximal points at the base of cochlea.
- Lower sounds had maximal points at the apex of cochlea.
Thank you.

There are two main ways to describe how loud a sound is. One is
that you can describe its intensity, I, measured in W/m2, which is
the amount of energy per unit time, per unit area, transported by
the sound. However, this is not very close to the human experience
of sound loudness. The human experience of loudness (actually like
the way most of our senses work) is that each factor of 10 in
intensity sounds like the same sized...

The data below were obtained to predict the sound frequency to
which a person’s ear will respond based upon the length of time a
person has been exposed to a high level of noise. Here “length of
exposure” is the amount of time in weeks that a person has been
living close to a major airport and the “hearing range” is reported
in thousand cycles per second. Length of exposure In weeks (Left)

(1) (A)You approach a stationary sound source with a speed such
that the frequency of sound you hear is 17% greater than the actual
frequency. With what speed are you approaching the sound source?
Use the speed of sound in air as 343 m/s.
(B)Two trains approach each other on separate but adjacent
tracks. Train 1 is traveling at a speed of 31.9 m/s and train 2 at
a speed of 27.6 m/s. If the engineer of train 1 sounds...

Two sources emit sound with the same frequency. One
source is at rest and the other is moving at a rate of 5 m / s
toward the stationary observer. Observers hear kites 6 times per
second. Determine the frequency of the sound emitted by the
source.
