The Hearing Sense

Question 1

Audition

Answer 1

The biological process by which our ears process sound waves

Question 2

Sound Waves

Answer 2

Vibrations of molecules that travel through the air

Question 3

Amplitude

Answer 3

Height of the sound wave (greater compression), the psychological quality of loudness

Question 4

Frequency

Answer 4

The number of wavelength cycles in a unit of time, measured using hertz, determines the highness or lowness of the sound (pitch)

Question 5

Pinna

Answer 5

The outer ear, the visible part of the ear (opening unto the head) that protrude from our heads (design to catch sound waves), Pinna direct sound waves into the ear canal (auditory canal)

Question 6

Tympanic Membran

Answer 6

The eardrum, sound waves make the eardrum vibrate (conduction)

Question 7

Middle Ear

Answer 7

Sound waves travel to vibrate the bones (auditory ossicles) of the ear

Question 8

Place Theory

Answer 8

In hearing, explain how we distinguish high-pitched sounds that possess a frequency that exceeds 5000 hertz

Question 9

Frequency theory

Answer 9

We hear pitch based on how fast the hair cells vibrate

Question 10

The McGurk Effect

Answer 10

Interaction with vision and hearing-an illusion that when auditory component of one sound is paired with visual component of another sound leading to a third sound.
