Audio Quality Measurement
Audio system measurements are made for several purposes. Designers take measurements so that they can 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. Some aspects of measurement and specification relate only to intended usage. Audio system measurements often accommodate psychoacoustic principles to measure the system in a way that relates to human hearing.

Famous quotes containing the words quality and/or measurement:
“The quality of American life is an insult to the possibilities of human growth ... the pollution of American space, with gadgetry and cars and TV and box architecture, brutalizes the senses, making gray neurotics of most of us, and perverse spiritual athletes and strident self-transcenders of the best of us.”
—Susan Sontag (b. 1933)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
