Summary in Audition

Question 1

is the sense of hearing.

Answer 1

Audition

Question 2

is the number of cycles of a periodic wave per unit of time

Answer 2

Frequency

Question 2

is the height of a periodic curve measured on its vertical axis

Answer 2

Amplitude

Question 3

is the simpliest type of sound, characterized by a single sine
wave.

Question 4

is completely random combinations of sound waves.

Question 5

is a unit used to express a difference in intensity between two
sounds, equal to 20 times the common logarithm of the ration of
two levels.

Question 6

is characterized by the amplitude. Thus, high-amplitude
waves are perceived as loud sounds while low-amplitude waves
are perceived as soft sounds.

Question 7

is characterized by the amplitude. Thus, high-amplitude
waves are perceived as loud sounds while low-amplitude waves
are perceived as soft sounds.

Question 8

is characterized by the frequency. Thus, low-frequency waves
are perceived as low-pitched sounds while high-frequence waves
are perceived as high-pitched sounds.

Question 9

is a unit of sound frequency equal to one cycle per second

Question 10

_ are sounds at frequencies above the range of human hearing,
or higher than about 20,000 Hz

Question 11

is the wave having the lowest frequency in a complex tone.

Question 12

s an additional wave produced by a complex tone that is an
integer multiple of the tone’s fundamental frequency.

Question 13

is the quality of sound that distinguish it from other sounds of
the same pitch and volume

Question 14

are sounds at frequencies below the range of human hearing,
or lower than about 20 Hz

Question 15

s the visible part of the outer ear

Question 16

is a tube-shaped structure in the outer ear that leads to the
tympanic membrane membrane

Question 17

s one of the chambers found in the cochlea.

Question 18

s the fluid-filled structure of the inner ear containing auditory
receptor.

Question 19

are one of the muscles responsible for the acoustic reflexes.
