February 2022 Meeting Notice: Merlijn Van Veen – AES75 – AES standard for loudspeaker measurement

The next online meeting of the AES Melbourne Section will be on Monday 14th February 2022 at 7:30pm AEDT (UTC+11).

Merlijn Van Veen, Chair of the AES Standards Task Group SC-04-03-A and Senior Technical Support & Education Specialist at Meyer Sound will present on the topic of:

AES75: AES standard for acoustics  
Measuring loudspeaker maximum linear sound levels using noise

Merlijn will briefly explore the background and impetus for this project. The AES Standards procedure will be explained and demonstrated, including challenges faced by the SC-04-03-A Task Group and how the Group’s activities have inspired development within other standard bodies. The session will close with a description of the remaining development steps.

This standard details a procedure for measuring maximum linear sound levels of a loudspeaker system or driver using a test signal called M-Noise. In order to measure maximum linear sound levels meaningfully and repeatably, a signal is required whose RMS and peak levels as functions of frequency have been shown to be representative of program material.

About Merlijn Van Veen:
After studying studio recording and jazz piano at the Royal Conservatoire in The Hague, Merlijn started his career at the Dutch Broadcast Company doing sound engineering for TV shows such as “Big Brother.” He also worked 10 years at Harlekijn Holland where he annually mixed more than 150 live performances throughout Europe and internationally before deciding to start his own education program in gratitude for the willingness of others to share their knowledge and experience.

He has developed several calculators to aid in the process of teaching including the Subwoofer Array Designer. Until recently, he was also principal teacher for sound reinforcement at the Royal Conservatoire in The Hague for the “Art of Sound” under-graduate and post-graduate program.

Merlijn is the moderator of the “test & measurement” board of the ProSoundWeb LAB forums. He provided ongoing aid and support to the 3rd edition of Bob McCarthy’s book “Sound Systems: Design & Optimization.” Merlijn’s articles are published regularly in Live Sound International magazine.

Based in Germany, Merlijn joined Meyer Sound’s global education leadership team in 2018. Merlijn hosts education webinars and roundtable discussions as well as doing design work.

All are welcome.
