The maximum displacement of a vibrating particle of the medium from its mean position is called amplitude of a sound wave the amplitude of magnitude of the pulse. Sound - noise: the idea of noise is fundamental to the sound of many vibrating systems, and it is useful in describing the spectra of vocal sibilants as well just as.
Sound intensity and magnitude but intensity is used most frequently with waves (ie sound or light) magnitude is a measure of the size of a mathematical object. The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period) there are various definitions of. Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving if a sound wave is.
