  1. long waves
  2. short waves
23
Q

Amplitude is measured in what?

Module 20

A

decibels

24
Q

zero decibels equals what in the process of hearing?

Module 20

A

zero decibels = our absolute threshold (for hearing)

25
Q

Loudness is determined by what?

Module 20

A

the number of activated hair cells

more cells activated = higher loudness it gets

26
Q

Module 20

A

place theory

27
Q

What theory describes the following:

in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch (also called temporal theory)

Q

What principle goes with the frequency theory (what is it called)?

Q

What theory describes the following:
