'''Audio system measurements''' are used to quantify [[audio system]] performance. These [[measurement]]s are made for several purposes. Designers take measurements to specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects of an audio path are within limits considered acceptable. Audio system measurements often accommodate [[psychoacoustic]] principles to measure the system in a way that relates to [[human hearing]].
