Sound- (Music, Hearing, Using)

Front

What type of waves does sonar use to determine distances?

Back

Ultrasound waves.

Front

In a wind instrument, what happens to the pitch when the column of air is shorter?

Back

The pitch becomes higher.

Front

What is the function of the eardrum?

Back

The eardrum vibrates in response to sound waves.

Front

In stringed instruments, how does the length of the string affect the pitch?

Back

Shorter strings produce a higher pitch.

Front

What occurs in the inner ear?

Back

Sound waves are converted into nerve impulses.

Front

What is sound?

Back

Sound is a vibration that travels through air, water, or solids.

Front

What is the difference between infrasound and ultrasound?

Back

Infrasound is below the range of human hearing (<20 Hz), while ultrasound is above the range of human hearing (>20 kHz).

Front

How does frequency affect the pitch of a sound?

Back

Higher frequency results in a higher pitch.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the loudness of the sound.

Front

What is resonance in music?

Back

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