Question

Which wave property determines : (a) loudness (b) pitch

Answer 1

Loudness:

1. The amplitude of a sound determines its loudness.
2. The amplitude of vibration, or the amount whereby the perceiving element or entity vibrates, determines the intensity or volume of a sound. The loudness of a sound diminishes as the distance from the source improves or doubles, whereas the amplitude of vibration rises.

Pitch:

1. The pitch of the sound is determined by the frequency of the wave.
2. The pitch fluctuates as the number of vibrations per second fluctuates or varies. The pitch produced by a tuning fork is determined by the length of its own prongs.
