Question #8b782

Answer 1

Loudness and pitch are 2 characteristics of sound. Loudness is measured in Decibel (dB) and pitch is measured in Hertz (Hz).

Loudness depends upon the amplitude of sound whereas pitch depends upon the frequency of sound.

If the amplitude is large, the sound is loud. If the amplitude is small, the sound is feeble.
On the other hand, the higher the frequency, the higher is the pitch and the lower the frequency, the lower is the pitch.

Answer 2

They're based on different properties of a wave.

Explanation:

Loudness, or Intensity, is directed related to amplitude of a sound wave. It matters how far the molecules are displaced from their mean.

Pitch is related to the frequency of a sound wave. In other words, how often the oscillations happen.

A sound may be extremely soft but of a high pitch, for example whistling, and vice versa.
