Auditory perception in acoustics

In [acoustics](/source/Acoustics), the **prefix** of a [sound](/source/Sound) is an initial phase, the onset of a sound quite dissimilar to the ensuing lasting [vibration](/source/Vibration).

The term was coined by J. F. Schouten (1968, 42), who called it one of *at least five major acoustic parameters* that determine the *elusive attributes of [timbre](/source/Timbre)*.
