AES Fall Convention 2022

MOTIVATION: the AES Technical Committee on Automotive Audio [TC-AA] has recognized that currently there is no consensus when it comes to measuring essential audio attributes in a car.

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 for results would be established.

The White Paper will be a living document that will evolve; and, it is hoped, will lead to standards down the road.

The group will report three measurements: Frequency Response, Max SPL, and Impulsive Distortion (squeak and rattle).

FORMAT: 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 (analysis of real acquisitions from vehicles using the recommended stimuli and measurement methods), and solicit feedback from the audience.

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