Acoustic Testing Solutions

 

Transmission Suite

A transmission suite can be considered the opposite of an anechoic chamber because its boundaries reflect, rather than absorb sound energy. Transmission suites are essentially two reverberation rooms back to back and are designed for the determination of sound power output of noise sources, transmission loss of partitions, insertion loss of silencers, response characteristics of microphones and random incidence absorption coefficients of materials.

Listening Rooms

IAC Acoustics produces listening rooms for testing the sound quality of various noises associated with a certain vehicle. These important facilities play a large part in the R&D process, utilising first hand market research data.

 

 

Quiet Rooms/Modal Analysis Rooms

Quiet rooms are similar to VSAC's, except without a chassis dynamometer. Quiet rooms are typically facilities for taking acoustic measurements around a stationary or idling vehicle. Noise from components and tangible areas of a vehicle that a consumer will interact with such as handles, switches, door closures and windscreen wipers are measured in quiet rooms.

 

 

Coupled Rooms

These are supplied in a variety of different scenarios, all are based on room to room noise measurements and associated with product testing and development.

 

 

Engine Test Cells

Engine Noise Test Cells (ENTC's) are typically environments for testing a standalone engine. Usually hemi-anechoic in design, an ENTC shares many characteristics with IAC VSAC chambers, but without a chassis dynamometer.

 

 

Solutions for all

Through years of providing acoustic solutions to many of the large automotive companies we also provide systems and products to many of the independent tuning and engine development companies.
