Question 1

The pitch of a sound corresponds to which aspect of the sound wave?

Accepted Answer

The pitch of a sound corresponds to its frequency, which is the number of vibrations or cycles per second in the sound wave.

Question 2

In the church choir,Madeline is a soprano and sings with a higher pitch than Amanda,who sings alto.The difference in tone between the two ladies is due to which aspect of the sound waves being produced by each lady?

Accepted Answer

The pitch or tone of a sound is determined by its frequency, which is the number of cycles per second in the sound wave. Sopranos sing with a higher pitch because they produce sound waves with a higher frequency than altos.

Question 3

The three small bones of the middle ear are called the

Accepted Answer

The three small bones of the middle ear are commonly referred to as the auditory ossicles, which consist of the malleus, incus, and stapes. They are responsible for transmitting sound vibrations from the eardrum to the inner ear. The other answer choices (A, B, and C) are not commonly used terms for describing the middle ear bones.

Question 4

Which of the following is a membrane on the cochlea that is attached to the stapes and moves back and forth,making waves in the fluid inside the cochlea?

Accepted Answer

The membrane on the cochlea that is attached to the stapes and moves back and forth, making waves in the fluid inside the cochlea, is called the oval window. The tympanic membrane is also known as the eardrum and is located at the beginning of the middle ear. The auditory ossicles are a series of three small bones in the middle ear that transmit sound vibrations to the inner ear. The pinna is the visible part of the ear that collects sound waves and channels them into the ear canal.

Question 5

The eardrum is linked with the cochlea by the

Accepted Answer

The auditory ossicles (malleus, incus, and stapes) connect the eardrum to the inner ear, specifically the oval window of the cochlea. This helps to amplify and transmit sound vibrations to the fluid-filled cochlea. Stereocilia, the hair-like structures on the sensory cells of the organ of Corti, convert sound vibrations into neural signals. The auditory nerve then carries these signals to the brain for interpretation.

Question 6

Which one of the following sequences is the correct one for audition?

Accepted Answer

The correct sequence for audition starts with the eardrum, then moves to the ossicles, followed by the cochlea, and ending with the hair cells. This sequence allows for sound waves to be collected and amplified by the outer ear, transmitted through the middle ear via the ossicles, converted into neural signals by the inner ear in the cochlea, and finally interpreted by the brain through the firing of hair cells in the cochlea.

Question 7

The artist Van Gogh cut off the external part of his ear.A psychologist would refer to the part that was cut off as the

Accepted Answer

The external part of the ear that extends from the head is called the pinna, which is the part that Van Gogh cut off. The cochlea, auditory ossicles, and stereocilia are all internal structures of the ear.

Question 8

The three auditory ossicles are the malleus,incus,and the

Accepted Answer

The three auditory ossicles are the malleus (hammer), incus (anvil), and stapes (stirrup), with the stapes being the smallest bone in the human body.

Question 9

The number of waves per second that corresponds to perceived pitch is called

Accepted Answer

The number of waves per second is known as frequency. Pitch is closely related to frequency, as a higher frequency usually corresponds to a higher perceived pitch.

Question 10

Grandma told the grandkids that their "PaPa" was right about the "little hammer and other things" being in their heads.She then added that their inner ear looked like a snail.This fluid-filled structure that looks like a snail is the

Accepted Answer

The sentence mentions that their inner ear looks like a snail, which refers to the cochlea. The pinna is the outer part of the ear, the auditory ossicles are bones in the middle ear, and umami is a taste sensation. Therefore, the best choice is C) cochlea.

Question 11

In the auditory system,the first anatomical structure that is set in motion by the sound wave is

Accepted Answer

The sound wave first hits the eardrum (tympanic membrane), which vibrates in response to the sound. This vibration is then transmitted to the ossicles (including the malleus, incus, and stapes), which amplify the vibration further and transmit it to the cochlea via the oval window.

Question 12

The physical "height" of a sound wave that tells how much energy the wave contains is called

Accepted Answer

The physical "height" of a sound wave that tells how much energy the wave contains is called amplitude.

Question 13

The thin membrane that moves in and out in response to sound waves colliding with it and passes the vibration on to the middle ear is the

Accepted Answer

The tympanic membrane, also known as the eardrum, is the thin membrane that moves in response to sound waves and passes the vibration on to the middle ear. The other options (auditory nerve, basilar membrane, and auditory ossicle) are all parts of the inner ear or nerve pathways involved in hearing, but they do not directly receive sound vibrations.

Question 14

The external,or visible,part of the ear is called the

Accepted Answer

The visible part of the ear is known as the pinna, also referred to as the auricle. The cochlea is a spiral-shaped part of the inner ear responsible for converting sound vibrations into electrical signals. The inner ear includes the cochlea and the vestibular apparatus for balance. The tympanic membrane, also known as the eardrum, is a thin layer of tissue that separates the outer ear from the middle ear.

Question 15

The Wretched Flamingo,a local punk rock band,was so loud during their practice sessions that the parents of one band member built them a "music shed" a significant distance from the house.This loudness was due to the

Accepted Answer

The loudness of a sound is determined by the amplitude, or height, of the sound waves. Higher amplitude sound waves are perceived as louder.

Question 16

Grandpa teased his grandchildren by saying that they have little hammers,anvils,and stirrups in their heads.They hollered,"No,you're wrong,PaPa." However,their grandpa was right,since these are the common names for the

Accepted Answer

The auditory ossicles are the three smallest bones in the human body, located in the middle ear. They are commonly referred to as the hammer (malleus), anvil (incus), and stirrup (stapes), which are the same terms Grandpa used to describe the structures in his grandchildren's heads.

Question 17

The part of the ear that acts as a funnel to concentrate sounds and guide them into the ear canal is called the

Accepted Answer

The pinna, also known as the auricle or outer ear, is the visible part of the ear that acts as a funnel to concentrate sounds and guide them into the ear canal. The other options are parts of the middle and inner ear that are involved in different aspects of the hearing process.

Question 18

The loudness of a sound corresponds to which aspect of a sound wave?

Accepted Answer

The amplitude of a sound wave determines its loudness. Greater amplitude means greater displacement of air molecules, resulting in a louder sound. Frequency relates to the pitch of the sound wave, while rarefaction and compression describe areas of low and high pressure in the wave respectively.

Question 19

Amplitude is to loudness as frequency is to

Accepted Answer

Amplitude affects loudness, while frequency affects pitch. A higher frequency corresponds to a higher pitch, while a lower frequency corresponds to a lower pitch.

Question 20

Frequency is to pitch as amplitude is to

Accepted Answer

Amplitude refers to the intensity or strength of a sound wave, which is perceived as loudness. Therefore, the correct choice is D) loudness.
