Question 2

The part of the ear we see is called the
A)cochlea.
B)pinna.
C)tympanic membrane.
D)ossicle.

Accepted Answer

The visible part of the ear is called the pinna or auricle.

Question 3

Question 4

Our sense of taste is called
A)gustation.
B)olfaction.
C)proprioception.
D)the vestibular sense.

Accepted Answer

Our sense of taste is called gustation.

Question 5

Brightness refers to the intensity of light. The corresponding term when discussing sound is
A)hue.
B)loudness.
C)pitch.
D)timbre.

Accepted Answer

Loudness is the intensity of sound, just as brightness is the intensity of light.

Question 6

One theory of pitch perception is the ________ theory, which suggests that the rate at which neurons in the ear fire produces different pitches. This theory is particularly effective at explaining humans' perception of lower pitches.
A)place
B)frequency
C)volley
D)opponent-process

Accepted Answer

The frequency theory suggests that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch. This theory is particularly effective for explaining the perception of lower pitches.

Question 7

A whistle that gives a sound so high that it can only be heard by dogs, but not humans, exploits which aspect of the auditory system?
A)Loudness
B)Timbre
C)Pitch
D)Decibels

Accepted Answer

The whistle exploits the aspect of pitch, as it produces a sound at a frequency that is too high for humans to hear.

Question 8

Once sound waves have been converted into neural activity, the ________ carries them to the brain for auditory perception.
A)auditory nerve
B)basilar membrane
C)cochlea
D)pinna

Accepted Answer

The auditory nerve carries the neural activity generated by the movement of the auditory hair cells in the cochlea to the brain. The basilar membrane and cochlea are involved in the initial conversion of sound waves into neural activity, and the pinna helps collect and funnel sound waves towards the ear canal, but they do not carry the neural activity to the brain for auditory perception.

Question 9

Our sense of hearing is called
A)audition.
B)gustation.
C)olfaction.
D)proprioception.

Accepted Answer

Our sense of hearing is called audition.

Question 10

Which of the following would NOT be considered one of the ossicles?
A)Pinna
B)Hammer
C)Anvil
D)Stirrup

Accepted Answer

The pinna is not one of the ossicles - it is the visible part of the outer ear that collects and directs sound waves towards the ear canal. The ossicles are the three tiny bones in the middle ear that transfer sound vibrations from the eardrum to the inner ear. The ossicles are the hammer (malleus), anvil (incus), and stirrup (stapes).

Question 11

Loudness is associated with a sound wave's
A)amplitude.
B)length.
C)pitch.
D)timbre.

Accepted Answer

The amplitude of a sound wave is directly related to its loudness. The higher the amplitude, the louder the sound. Therefore, choice A is correct. Length and pitch are related to frequency and not loudness. Timbre refers to the quality or complexity of a sound, which is not directly related to loudness.

Question 12

The wave frequency of a sound is what we refer to as its ________.

Accepted Answer

The answer of The wave frequency of a sound is...

Question 13

Human perception of high-pitched tones is best explained by ________ theory.
A)frequency
B)opponent process
C)place
D)volley

Accepted Answer

The place theory of hearing explains perception of high-pitched tones. This theory suggests that different areas of the basilar membrane in the cochlea respond to different frequencies, allowing us to distinguish between different pitches. High frequencies are detected by hair cells located near the base of the cochlea, while lower frequencies are detected by hair cells located farther up the cochlea.

Question 14

As we age, it becomes more difficult for us to hear ________ sounds.
A)high-frequency
B)low-frequency
C)low- to moderate-frequency
D)moderate-frequency

Accepted Answer

As we age, our ability to hear high-frequency sounds decreases, while our ability to hear low-frequency sounds remains relatively unchanged. This is because the hair cells in the inner ear that are responsible for detecting high-frequency sounds are more vulnerable to damage and deterioration over time. Therefore, high-frequency sounds, such as the chirping of birds or the ringing of a cell phone, may become harder to hear as we age.

Question 15

The difference between high-definition television and regular television is analogous to which component of sound?
A)Pitch
B)Loudness
C)Amplitude
D)Timbre

Accepted Answer

High-definition television primarily differs from regular television in the clarity and detail of the image, which is analogous to timbre in sound. Timbre refers to the quality or color of a sound that makes it distinct from another sound at the same pitch and loudness, similar to how high-definition enhances the detail and quality of a visual image.

Question 16

The complexity or quality of sound that makes instruments, voices, and other sources of sound unique is called
A)audition.
B)acuity.
C)timbre.
D)wavelength.

Accepted Answer

Timbre is the quality of sound that distinguishes one instrument or voice from another. It is also sometimes referred to as tone color or tone quality. Audition refers to the process of perceiving sound, acuity refers to the sharpness or sensitivity of perception, and wavelength refers to the physical characteristic of sound waves. None of these terms specifically refer to the unique quality of different sources of sound.

Question 17

The bony, spiral-shaped sense organ used for hearing is the
A)basilar membrane.
B)cochlea.
C)timbre.
D)pinna.

Accepted Answer

The bony, spiral-shaped sense organ used for hearing is the cochlea. The basilar membrane is inside the cochlea and helps in hearing. Timbre is a characteristic of sound related to its quality or texture. Pinna is the outer part of the ear that collects sound waves.

Question 18

Quentin is suffering from a disorder that causes him to have problems recognising everyday objects. The other day he was looking at a wine glass and couldn't come up with its name. He said to his wife, "I want one of those things that you hold the wine in", but try as he did, he could not find the word "glass". This demonstrates a form of visual ________.
A)ataxia
B)apraxia
C)aphasia
D)agnosia

Accepted Answer

Quentin is experiencing a form of agnosia, specifically visual agnosia, which is a disorder where individuals have difficulty recognizing or identifying everyday objects.

Question 19

Pete has played lead guitar in a rock band for years. He would often turn the volume on his guitar up loud and spend a great deal of time in front of the speakers during the shows. His resulting hearing loss over the past few years is most likely the result of
A)conductive deafness.
B)nerve deafness.
C)noise-induced hearing loss.
D)tinnitus.

Accepted Answer

Pete's hearing loss is likely a result of noise-induced hearing loss, caused by his exposure to loud music for a prolonged period of time. Conductive deafness typically results from problems with the ear canal or middle ear, whereas nerve deafness is caused by damage to the inner ear. Tinnitus is a symptom of hearing loss and may accompany any of the aforementioned conditions, but it is not a specific cause of hearing loss itself.

Question 20

Humans can hear sounds ranging from
A)20 to 2000 dB.
B)20 to 2000 Hz.
C)20 to 20 000 dB.
D)20 to 20 000 Hz.

Accepted Answer

The range of sound frequencies that humans can hear is typically from 20 Hz to 20,000 Hz. The loudness or intensity of sound is measured in decibels (dB), but the range of human hearing is generally considered to be from 0 dB (the threshold of hearing) to 120 dB (the threshold of pain). Therefore, option D is the correct choice as it represents the range of frequencies that human ear can capture.
