AES Convention– New York – October 16-19, 2019
Although Listen won’t be exhibiting, president Steve Temme will be at the event and will be participating in two product development sessions detailed below.
Product Development: PD09 – Does Automotive Audio Need a Systems Approach?
Thursday, October 17, 1:30 pm — 3:00 pm (1E09)
Chair: Roger Shively, JJR Acoustics, LLC
Panelists: John Busenitz, Bose Corporation, Pietro Massini, Ask Industries S.p.A, Greg Sikora, Harman International, Steve Temme, Listen, Inc.
Some component specifications do not translate to good system performance. A good example is resonance frequency. This often does not correspond well to performance characteristics in the automotive environment. Some potential improvements would be low-frequency SPL, or a parameter combination such as Fs/Qts or EBP (Fs/Qes). The system performance goals should drive the transducer component specification. Hence, this workshop will host leading industry experts in automotive audio and test/measurement solutions to discuss pros and cons of component vs. system specifications.
Product Development: PD10 – Diagnostics for Production Vehicle Audio Systems
Thursday, October 17, 3:15 pm — 4:30 pm (1E09)
Presenters: Jonathan Gerbet, Klippel GmbH, Steven Hutt, Equity Sound Investments, Steve Temme, Listen, Inc.
Audio systems in production vehicles are known to exhibit vehicle to vehicle performance variance [1]. The root causes of variance can include loudspeaker driver manufacturing tolerance, mounting issues such as missing or misaligned gaskets, or wrong loudspeaker drivers mounted in the system. A diagnostics method to compare actual production vehicle audio systems is defined along with a method for correction and calibration of production vehicle audio systems. The diagnostics procedure may be implemented at production end-of-line, at vehicle distribution center or at a dealer service center in the field after delivery to a customer.
