Meeting Report: February 2022 – AES75 “Measuring Loudspeaker Maximum Linear Sound Levels Using Noise”

On Monday February 14th the AES Melbourne Section turned to Zoom again for yet another online meeting.

Over thirty members and guests joined the meeting to hear Meyer Sound’s Merlijn Van Veen Chair of AES Task Group SC-04-03-A present on the current revision of the AES75 Standard “Measuring Loudspeaker Maximum Linear Sound Levels Using Noise”

After welcoming everyone, Section Chair Graeme Huon introduced Merlijn who started by explaining the work of the Standards workgroup tasked with developing this standard, noting that the Task Group consisted of more than 70 people from a wide range of related organizations who had met fortnightly for 2 years to thrash out this document.  He went on to explain the genesis of the M-Noise signal within the Meyer Sound company, and its journey to consideration for inclusion in an AES Standard.
