Detection and Production of Sound Quiz

What type of waves are sound waves?

• Light waves

• Mechanical waves

• Electromagnetic waves

• Radio waves

What is the relationship between pitch and frequency?

• Pitch is the visual representation of frequency

• Pitch is the perceptual quality of sound related to its frequency.

• Pitch has no relationship to frequency

• Frequency is the perceptual quality of sound related to its pitch

How is amplitude related to loudness?

• Amplitude is directly related to loudness.

• Amplitude has no effect on loudness

• Amplitude is inversely related to loudness

• Amplitude is unrelated to loudness

What is resonance and how does it relate to vibration?

• Resonance has no effect on the vibration of a system

• Resonance only occurs in solid materials and not in other forms of matter

• Resonance is the decrease in amplitude when the frequency of a force matches the natural frequency of vibration

• Resonance is the increase in amplitude that occurs when the frequency of a force applied to a system matches the natural frequency of vibration of the system.

How do humans detect sound?

• Through the nose

• Through the skin

• Through the ear

• Through the eyes

What is the speed of sound in air at room temperature?

• 200 meters per second

• 100 meters per second

• 500 meters per second

• 343 meters per second

What is the unit of measurement for frequency?

• Miles

• Gallons

• Kilograms

• Hertz (Hz)

How does the shape of a musical instrument affect the sound it produces?

• It can make the sound smell different

• It can change the color of the sound

• It can change the pitch, volume, and tone of the sound.

• It has no effect on the sound

What are the different parts of the human ear involved in sound detection?

• Outer ear, middle ear, and inner ear

• Left ear, right ear, and back ear

• Front ear, back ear, and top ear

• Top ear, bottom ear, and side ear

How does the Doppler effect relate to sound waves?

• The Doppler effect changes the color of sound waves

• The Doppler effect has no impact on sound waves

• The Doppler effect causes a change in frequency and pitch as the source of the sound moves relative to the observer.

• The Doppler effect only affects the volume of sound waves
