New Automotive Test Sequence

We have a new automotive test sequence to measure Transient Distortion (also known as buzz, squeak, and rattle, Rub & Buzz, or impulsive distortion), Frequency Response, and Max SPL to the suggested measurement methods set out in the AES Technical Committee on Automotive Audio’s recently published white paper on in-car acoustic measurements. The three measurements are incorporated into one overall test sequence, making it fast and simple to run the entire suite of tests. This sequence facilitates evaluation of the committee’s proposals, and also serves as a basis for any similar in-house measurements. The white paper, which may be obtained from the TC-AA, outlines both measurement methods and physical configuration such as microphone and seat positioning in an effort to simplify comparison between vehicles.

Automotive Audio Testing Seminar

July 21st, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)
July 27th, 10.00am China time

In this practical online seminar, Steve Temme will demonstrate in-car measurement of frequency response, Max SPL, and Buzz, Squeak and Rattle using a Bluetooth connection. He will discuss considerations such as physical setup, infotainment system controls and the measurement parameters. Steve and his colleagues will then discuss connectivity for automotive testing, explaining and demonstrating the various connectivity options including USB drive, Bluetooth and A2B bus. Finally, we’ll take a look at some of the other audio measurements that you can make using SoundCheck, for example active noise cancellation and voice assistance readiness. 

在这个实用的网络研讨会中,Steve Temme 将演示如何使用蓝牙连接进行车内测量,以测量频率响应、最大 SPL 以及异常音。 他将讨论物理设置、信息娱乐系统控制和测量参数等考虑因素。 然后,Steve和他的同事将讨论汽车测试的连接性,解释和演示各种连接选项,包括 USB 驱动器、蓝牙和A2B 总线。 最后,我们将看看其他您可以透过SoundCheck进行的音频测量,例如主动降噪以及voice assistance readiness测量。
