Question 1

presumes that we hear different pitches along the cochlea’s basilar membrane

Answer 1

place theory

Question 2

What is the problem with place theory

Answer 2

it doesn’t explain how we can hear low-pitch sounds

Question 3

the theory that the rate of nerve impulses traveling up the auditory nerve the whole basilar membrane vibrates with the incoming sound wave, triggering neural impulses to the brain at the same rate as the sound wave (auditory nerve)

Answer 3

frequency theory

Question 4

What is the problem with frequency theory

Answer 4

it doesn’t explain how can sense sounds with frequencies above 100 waves per second

Question 5

Explain the volley principle

Answer 5

neural cells can alternat firing. By firing in rapid succession they achieve above 1000 waves.
