Scope

This Standard is a set of recommendations for subjective evaluation of high-performance loudspeaker systems. It is believed that, for certain audio components including loudspeakers, subjective evaluation is a necessary adjunct to objective measurements. The strong influence of listening conditions, program material and of individual evaluators is recognized. This document seeks, therefore, to assist in avoiding testing errors rather than to attempt to establish a correct procedure
