AES Standards Webinar on measuring max SPL of loudspeakers using random noise that simulates music

The first presentaton in the AES Standards webinar series will take place on March 29 at 12:00 noon, ET, and will feature Merlijn Van Veen and Roger Schwenke, co-chairs of the SC-04-03-A Task Group, discussing measurement of loudspeaker maximum SPL using random noise that simulates music. 

Van Veen and Schwenke will discuss the work of the SC-04-03-A Task Group developing a procedure for loudspeaker test and measurement using a test signal called MNoise. It is unique in that its crest factor as a function of frequency mimics that of real music, better simulating what transducers encounter in use than previous methods using pink noise. They will briefly explore the background and impetus for this project and the challenges it may solve. The standard’s procedure will be explained and demonstrated using readily available equipment. Included will be a discussion of challenges that arose during the standard development, but also how it inspired different applications within other standard bodies. The presentation will review the timeline for remaining work and describe how you can get involved.
