Hearing

Question 1

Sound

Answer 1

Physical = pressure changes in medium
Perceptual = experience

Question 2

Pure tone

Answer 2

Change in air pressure occurring in a sine wave pattern

Question 3

Frequency

Answer 3

Number of cycles per second; measured in Hz; perception of pitch

Question 4

Amplitude

Answer 4

Size of pressure change; dB; perception in loudness

Question 5

Fundamental frequency

Answer 5

Repetition rate of a complex sound

Question 6

Harmonics

Answer 6

Pure tones that make up a complex tone

Question 7

First harmonic/fundamental

Answer 7

Pure tone with the same frequency as the complex tone

Question 8

Periodicity pitch

Answer 8

Pitch we perceive in tones that have harmonics removed; different timbre

Question 9

Tone height

Answer 9

Increasing pitch that accompanies increases in tone’s fundamental frequency

Question 10

Timbre

Answer 10

Quality that distinguishes between two tones that have the same loudness, pitch, and duration but still sound different

Question 11

Pinnae

Answer 11

• sound location

- catching sound stimuli

Question 12

Auditory canal

Answer 12

• protects tympanic membrane

- helps with resonant frequency

Question 13

Path through middle ear

Answer 13

Malleus➡️incus➡️stapes➡️oval window

Question 14

Ossicles

Answer 14

• increase pressure by concentrating vibrations

- amplify the sound that reaches the inner ear

Question 15

Phase locking

Answer 15

Firing of nerve fibers that takes place at the same time the pressure increases

Question 16

Pitch perception

Answer 16

• place with greatest vibration ➡️frequency

- firing rate ➡️ stimulus frequency
