Loudspeaker System Simulation Using Digital Techniques

Authors: Fincham, Laurie R.

AES Convention 50 · Paper L-14 · March 1975

Abstract

Objective loudspeaker measurements are usually made in order to help the engineer to eliminate the causes of audible defects in a loudspeaker and enable the system design to be optimized. Unfortunately, certain defects, notably coloration, are not readily diagnosed using traditional analog measuring methods although their presence is all too readily detected during listening tests. A new measuring method, using digital techniques, has been developed recently for obtaining the impulse response of a loudspeaker. Considerable additional insight into the objective performance of a loudspeaker is now obtained by either direct visual examination of the recorded impulse response or of other displays obtained from subsequent processing of the impulse response using a digital computer. All this additional information is of no value, however, unless its subjective significance can be established. It is a loudspeaker's sound quality that matters rather than its measured performance.
