The Call for Comment on DRAFT AES73id-xxxx, "AES information document for acoustics – Loudspeaker driver comparison chambers" was published 2019-03-05.
Acoustic performance measurements on loudspeaker drivers that are measured in different sites or with different equipment or methods are subject to variations in accuracy and repeatability. Similarly, end-ofline loudspeaker test systems often utilize small, arbitrarily shaped, driver measurement chambers that do not correlate from line to line, or from site to site. This document is motivated by the need for engineers in different locations to share accurate measurement data on specific or same type loudspeaker drivers and addresses some of the factors affecting repeatability of measurements in different locations. It considers factors affecting the interchangeability of measurement data from simple loudspeaker comparison chambers and discusses some performance capabilities.
