AES Fall Online 2021 – Streamcast – October 20-23, 2021

Our workshop “Loudspeaker Work-Bench Measurements” by Simon Steiner and Wolfgang Klippel will take place on October 21st, 2021 at 12 pm EDT | 6 pm CET.

Abstract: 
Transducers are usually clamped in a relatively large baffle and measured under anechoic conditions to approximate perfect acoustical half-space conditions. A new acoustical near field method is presented that uses an extremely small ROUND baffle at least 10 cm around the transducer and can be operated in a normal office, workshop, or any other environment. Holographic post-processing removes the acoustical short-cut and baffle reflections and suppresses room modes and gives accurate data in the near and far-field. Exploiting the symmetry of the transducer reduces the measurement time to 5 minutes while providing full directivity information. The near field scanner is a small add-on to the KLIPPEL laser vibrometer using the same robotics. This seminar discusses important electrical, mechanical, and acoustical measurement performed on the SCN work-bench according to IEC 60268-21 and 22. ➥ Sign up to save this to your schedule and view media!

White Paper: "In-car Acoustic Measurement" by Jayant Datta, Steve Temme, Hans Lahti and Stefan Irrgang

The presentation will take place on October 23rd, 2021 at 12 pm EDT | 6 pm CET.

If you’re interested on the work of the AES Technical Committee on Automotive Audio, please watch the discussion about the white paper of "In-car Acoustic Measurements".

There is a need for alignment between OEMs and Tier1 suppliers for robust and repeatable acoustic measurement methods, data and analysis formats. Hence, a working group has undertaken the task of creating a white paper focused on in-car acoustic measurements, where the measurement stimuli, conditions, and computations would be established.

This will be a living document that will evolve; and could lead to standards down the road. At the outset, the group has decided on three measurements: Frequency Response, Max SPL, and Impulsive Distortion (squeak and rattle).

This will be in the form of a panel discussion with five parts to it (listed below) – the purpose is to inform the AES community about this effort, provide an update, and solicit feedback.

Overview:

  • Frequency Response specifics
  • Max SPL specifics
  • Impulsive Distortion specifics
  • Solicit feedback via Live Q&A
