For a given frequency, the greater the amplitude of the wave the louder the sound. To discuss quality of sound we need to clarify the concept of overtones. Sounds are produced by vibrate at one definite frequency producing a pure tone. This is the way a tuning fork is usually used. When...
Loudness depends on the amplitude of the wave reaching the ear. For a given frequency, the greater the amplitude of the wave the louder the sound. To discuss quality of sound we need to clarify the concept of overtones. Sounds are produced by vibrating objects. If these objects are given a...
amplitude i. The amplitude of a wave is the maximum displacement, or the maximum value, it attains from its mean position during a cycle. It is both positive and negative. With sound waves, the greater the amplitude, the louder is the sound. ...
wave. The amplitude of an ocean wave, for example, is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. See more atwave....

When a mechanical wave propagates through a physical medium, the particles of the medium oscillate about their mean positions with their positions being sinusoidal functions of time. The maximum displacement of each particle relative to its mean position is the amplitude of the wa...
