1.6C Hearing

Which structure in the ear is responsible for converting sound waves into electrical signals?

• Eardrum

• Cochlea

• Ossicles

• Pinna

The place theory of hearing explains how we perceive:

• Low-pitched sounds

• All frequencies of sound

• High-pitched sounds

• Sound localization

Which type of hearing loss is caused by damage to the auditory nerve or cochlea?

• Conduction deafness

• Sensorineural deafness

• Tinnitus

• Presbycusis

A student is having difficulty hearing their teacher in a noisy classroom. Which hearing aid device might be recommended to directly stimulate their auditory nerve?

• Hearing aid

• Cochlear implant

• Bone conduction device

• Amplifier

The ability to determine the origin of a sound is known as:

• Pitch detection

• Frequency analysis

• Sound localization

• Auditory processing

Which theory of pitch detection suggests that groups of neurons work together to process higher frequency sounds?

• Place theory

• Frequency theory

• Volley theory

• Resonance theory

A person with conduction deafness is likely to have a problem with:

• The cochlea

• The auditory nerve

• The ossicles

• The auditory cortex

In the context of hearing, what does amplitude correspond to?

• Pitch

• Loudness

• Frequency

• Timbre

A psychologist is studying how people perceive different pitches. Which structure would they be most interested in examining?

• Eardrum

• Cochlea

• Ossicles

• Eustachian tube

When studying sound localization, researchers often focus on the differences between:

• Left and right ear input

• High and low frequencies

• Loud and soft sounds

• Fast and slow neural responses
