A)tympanic membrane; oval window 
B)oval window; tympanic membrane 
C)round window; oval window 
D)oval window; round window

Accepted Answer

The tympanic membrane (eardrum) forms the boundary between the outer and middle ear, whereas the oval window forms the boundary between the middle and inner ear. Choice A correctly identifies these two structures in the correct order. Choices C and D are incorrect, as the round window is located in the inner ear and has a different function in the hearing process. Choice B reverses the order of the two structures.

Question 2

Decibels (dB)are used to measure a sound's​ 
A)pitch. 
B)frequency. 
C)intensity.

Which of the following structures are found in the outer ear?​ 
A)the pinna and auditory canal 
B)the pinna and the tympanic membrane 
C)the auditory canal and the tympanic membrane 
D)the auditory canal and the oval window

Accepted Answer

The pinna and auditory canal are both structures found in the outer ear. The tympanic membrane is found in the middle ear, and the oval window is found in the inner ear.

Question 4

When Daniel drives down the street,other people stop and stare because of the loud,low-pitched sounds coming from the new sound system in his car. What types of sound waves are coming from Daniel's car?​ 
A)high amplitude, low frequency 
B)high amplitude, high frequency 
C)low amplitude, low frequency 
D)low amplitude, high frequency

Question 5

Sounds with frequencies below the range of human hearing are referred to as 
A)fundamental frequencies. 
B)pure tones. 
C)ultrasound. 
D)infrasound.

Accepted Answer

Infrasound refers to sounds with frequencies below the range of human hearing, typically below 20 Hz. A is incorrect because fundamental frequencies refer to the lowest frequency of a complex sound, not specifically sounds below human hearing. B is incorrect because pure tones refer to sounds with a single frequency, but not necessarily below human hearing range. C is incorrect because ultrasound refers to sounds with frequencies above the range of human hearing, typically above 20 kHz.

Question 6

Pain is typically experienced when people are exposed to sounds above _________ dB.​ 
A)60 
B)90 
C)110 
D)130

Accepted Answer

Pain is typically experienced when people are exposed to sounds above 130 dB, as this level of sound intensity can cause discomfort and potential damage to the ears.

Question 7

Which of the following structures funnels sound into the ear?​ 
A)the ossicles 
B)the pinna 
C)the tensor tympanum 
D)the stapes

Accepted Answer

The pinna, also known as the outer ear, funnels sound waves into the ear canal. The other structures listed help to transmit and amplify sound waves, but the pinna is responsible for collecting the sound waves and directing them towards the ear canal.

Question 8

Hertz (Hz)is used to measure a sound's​ 
A)loudness. 
B)intensity. 
C)frequency. 
D)amplitude.

Accepted Answer

Hertz (Hz) is a unit of measurement for frequency, which determines the pitch of a sound. Loudness is measured in decibels (dB), intensity refers to the amount of energy carried by the sound wave, and amplitude is the maximal displacement of the sound wave from its equilibrium position.

Question 9

The outer and middle ear both transmit sound through _________ and the inner ear uses a _________ medium in the process of transducing sounds waves to electrical energy.​ 
A)bone; mucous 
B)liquid; mucous 
C)air; liquid 
D)air; sodium

Accepted Answer

The outer ear collects and directs sound waves into the ear canal, which leads to the eardrum in the middle ear. The middle ear contains three small bones that transmit sound vibrations from the eardrum to the inner ear, which is filled with liquid. The fluid in the inner ear moves in response to the vibrations and stimulates hair cells, which then convert the mechanical energy into electrical signals that are sent to the brain. Therefore, the outer and middle ear use air as the medium to transmit sound, while the inner ear uses liquid to transduce sound waves.

Question 10

Sound waves with a single frequency are known as​ 
A)pure tones, which are rare in nature. 
B)pure tones, which are common in nature. 
C)complex tones, which are rare in nature. 
D)noise, which is common in nature.

Accepted Answer

Pure tones are sound waves with a single frequency, and they are rare in nature because most sounds are composed of multiple frequencies.

Question 11

Brandon's teeth are stained from his constant coffee drinking,so his dentist recommended that he switch to a new electric toothbrush that not only brushes teeth very rapidly,but also uses sound to reduce plaque and staining.What kind of sound is most likely generated by Brandon's new toothbrush?​ 
A)infrasound 
B)ultrasound 
C)pure tones 
D)noise

Accepted Answer

Ultrasound is commonly used in dental technology to remove plaque and stains, making it the most likely sound generated by Brandon's new toothbrush. Infrasound has a frequency below the range of human hearing and is not typically used in dental technology. Pure tones are single frequency sounds used primarily in audiology testing and are not relevant in this context. Noise is a broad term referring to any unwanted sound and does not specify a specific frequency or type of sound.

Question 12

Sound waves that do not show a regular,repeating pattern are perceived as​ 
A)loud. 
B)soft. 
C)pure tones. 
D)noise.

Accepted Answer

Sound waves that do not show a regular, repeating pattern are perceived as noise. This is because they are random and do not have a distinct pitch or tone. Examples of noise include static, white noise, and the sound of traffic.

Question 13

Sounds with frequencies above the range of human hearing are referred to as 
A)fundamental frequencies. 
B)pure tones. 
C)ultrasound. 
D)infrasound.

Accepted Answer

Ultrasound refers to sound waves with frequencies above 20,000 Hz, which is above the range of human hearing. Option A, Fundamental frequencies, refers to the lowest frequency of a complex wave, and is not related to high-frequency sound waves. Option B, Pure tones, refers to sound waves with a single frequency or frequency component, which can be within or outside of the audible frequency range. Option D, Infrasound, refers to sound waves with frequencies below 20 Hz, which are also outside of the range of human hearing.

Question 14

A)noise 
B)pure tones 
C)infrasound 
D)ultrasound

Accepted Answer

Infrasound is generally the type of sound used by whales for communication and is likely to be captured in the recordings made by Stephanie. Noise and ultrasound are less likely to be included, while pure tones are not typically used by whales for communication.

Question 16

A low frequency sound wave is perceived as​ 
A)quiet. 
B)loud. 
C)high pitched. 
D)low pitched.

Accepted Answer

Low frequency sound waves are perceived as low pitched.

Question 17

Which of the following is not one of the ossicles?​ 
A)the malleus 
B)the incus 
C)the pinna 
D)the stapes

Accepted Answer

The pinna is not one of the ossicles. The ossicles are the malleus, incus, and stapes, which are three tiny bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear. The pinna, also known as the auricle, is the visible external ear made of cartilage and skin that collects sound waves and directs them towards the ear canal.

Question 18

The primary function of the ossicles is to​ 
A)transfer sound energy from the air of the middle ear to the fluid of the inner ear. 
B)transfer sound energy from the fluid of the middle ear to the air of the inner ear. 
C)funnel sound. 
D)prevent damage from loud noises.

Accepted Answer

The ossicles (malleus, incus, and stapes) are the three smallest bones in the human body and their primary function is to transfer sound energy from the air of the middle ear to the fluid of the inner ear. This is important for hearing and for converting sound waves into electrical signals that the brain can interpret.

Question 19

High amplitude sound waves are perceived as​ 
A)quiet. 
B)loud. 
C)high pitched. 
D)low pitched.

Accepted Answer

High amplitude sound waves are perceived as loud. A high amplitude means that the sound wave has a larger variation in pressure, which causes a stronger sensation of sound.
