Sound Waves and Hearing Assessment

What is the relationship between frequency and pitch?

• Higher frequency sound waves produce higher pitch sounds.

• Higher frequency sound waves produce lower pitch sounds.

• Lower frequency sound waves produce higher pitch sounds.

• Frequency has no effect on pitch.

What is interference in sound waves?

• Interference occurs when two or more sound waves overlap, affecting their amplitude.

• Interference is the process of sound waves being absorbed by materials.

• Interference happens when sound waves travel in a vacuum without any medium.

• Interference refers to the change in frequency of sound waves due to temperature.

What is the speed of sound?

• The speed at which sound waves travel through a medium.

• The speed of light in a vacuum.

• The speed at which light travels through water.

• The speed of a car on a highway.

Through which part of the ear do sound waves enter?

• Ear canal

• Eardrum

• Cochlea

• Auditory nerve

What are sound waves with frequencies below the normal human range of hearing called?

• Ultrasound

• Infrasound

• Audible sound

• Subsonic sound

What is the role of the ear drum?

• The ear drum vibrates in response to sound waves, transmitting sound to the inner ear.

• The ear drum protects the inner ear from foreign objects.

• The ear drum helps in maintaining balance in the body.

• The ear drum amplifies sound waves before they reach the inner ear.

What is an echo?

• A type of musical instrument

• A reflected sound wave.

• A sound that is absorbed by materials

• A sound that travels in a straight line.

What is the Doppler Effect?

• The change in frequency of a wave in relation to an observer who is moving relative to the wave source.

• The phenomenon where light changes color as it moves away from an observer.

• The increase in sound intensity as the source approaches an observer.

• The changing pitch of a sound as the source moves relative to an observer.

What is the difference between pitch and loudness?

• Pitch refers to the volume of a sound, while loudness refers to how high or low a sound is.

• Pitch refers to how high or low a sound is, while loudness refers to the volume of the sound.

• Pitch and loudness are the same concepts and can be used interchangeably.

• Pitch refers to the speed of sound, while loudness refers to the intensity of sound.

What is resonance in sound?

• Resonance is the amplification of sound when an object vibrates at its natural frequency.

• Resonance is the process of sound waves bouncing off surfaces.

• Resonance is the reduction of sound intensity due to interference.

• Resonance is the creation of sound through electrical signals.
