Question

Two sounds X and Y are produced by loudspeakers.
The amplitude and frequency of each sound wave is given.
X- 1.3 amplitude/mm X- 475 frequency/Hz
Y- 2 amplitude/mm Y- 235 frequency/ Hz
How does sound Y compare with sound X?

Answer 1

Given:

Two sounds X and Y are produced by loudspeakers. The amplitude and frequency of each sound wave is given.

X- 1.3 amplitude/mm X- 475 frequency/Hz

Y- 2 amplitude/mm Y- 235 frequency/ Hz

To find:

Comparison between sounds X and Y.

Calculation:

• A sound with higher amplitude means the sound is much louder.

X has amplitude 1.3 mm and Y has amplitude 2 mm.

Hence , sound Y is much louder than sound X

• Frequency of a sound determines the pitch or shrillness of a sound.

Sound X has frequency 475 Hz , Sound Y has frequency 235 Hz.

So, Sound Y is less shrill (lesser pitch) than sound X.
