Anechoic Chamber: Keeping Buzz, Squeak and Rattle in Check

Saint-Gobain's anechoic chamber in Bristol, UK, can help you achieve noise-free applications and increase the quality perception of your car.

We have a unique Noise, Vibration and Harshness testing facility in the UK. It is helping us to gather and evaluate accurate data on squeak and rattle noises as well as vibration in many automotive systems but also other industries. Seats, doors, steering and compressors – we can test individual components and entire assemblies. Work with us to improve the noise-free performance of your systems using our state-of-the-art sound anechoic chamber test facility.

Saint-Gobain has many years’ experience testing in a partner’s anechoic chamber and has enlisted even more expertise in building our own facility. We have been supported by the renowned Institute of Sound and Vibration Research Consulting (ISVR) at the University of Southampton, as well as by leading sound and vibration measurement and analysis systems manufacturer Brüel & Kjær.

The components manufactured by Saint-Gobain, such as NORGLIDE^® Bearings and RENCOL^® Tolerance Rings, have a critical role to play in reducing buzz, squeak and rattle sounds in automotive systems over and above. Being able to accurately test their performance in entire assemblies enables us to identify areas ripe for improvement at both component and assembly level. The anechoic chamber, which absorbs sound wave reflections and is insulated against outside noises, is perfectly set up to accurately test complete systems rather than single components. The facility offers testing of, but not restricted to, the following applications: 

• Vertical seat testing
• Electric motors
• Electric power assisted steering
• Steering rack and yoke bearing
• Component level rattle testing

  Please see our Noise testing video in the chamber.

Here at Saint-Gobain we are proud of our heritage in innovation and creativity. The anechoic chamber in Bristol allows us to continue that tradition with a cutting-edge testing facility that is readily available and dedicated to discovering new and improved products. We invite system producers to work with us as we seek to reduce and finally eliminate the rattle, squeak and buzz sounds that bedevil perceptions of automotive quality!
