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. The research data gathered, aids in ‘tuning’ a vehicle to sound a certain way and is typically very different across models, even throughout a manufacturer’s vehicle range.

Manufactured from IAC’s Moduline®, a modular acoustic panel system, the facilities have to be isolated from any other interfering noise to gain the best results. IAC Varitone™ or AccuTone™ panels are then used inside the room to tune the absorption and hence reverberation times so that room reflections do not ‘colour’ the sound under assessment in chambers to enable testing to the ITU-R BS 1116-1 standard.
