Acoustic Test Chamber – for faster product development time

24 December 2015

G.R.A.S. Sound and Vibration is introducing a new, flexible production line acoustic test chamber, which is the latest in the range of anechoic chambers from G.R.A.S. and built on our vast acoustic experience in the field.

It is designed for quick and qualified acoustic test of cell phones, tablet PCs, Bluetooth speaker systems etc. including frequency response, THD, Rub & Buzz and microphone test, using optional sound source. It provides a flexible platform that can be configured to suit specific requirements. The chamber has a number of connections for injecting test and control signals to the Device Under Test (DUT):

• Repeatable testing and reliable data
• Easy open/close for quick and safe change of DUT
• Flexible test jig for easy adjustment to new DUT
• Flexible microphone mounting for both front- and backside speakers as well as edge-mounted speakers
• High-quality, high-sensitive ¼“ CCP measurement microphone included (G.R.A.S. 46BL)
• Individually calibrated frequency response

The Acoustic Test Chamber is indeed unique and something that will speed up product development time significantly. It can be deployed almost anywhere and essentially offers a benchtop anechoic chamber providing highly repeatable data.
This is the only commercially available complete front-end solution on the market, ready to use immediately after delivery.

The Acoustic Test Chamber has proven to be a useful tool not only for production line testing, but also for research and development. “From key customers we have received a positive response regarding the Acoustic Test Chamber. They have experienced a decrease in product development time due to the flexible platform and better access to test facilities” says Peter Wulf-Andersen, Product Manager at G.R.A.S. Sound and Vibration A/S.
