NVH Test Facilities
A Complete Solution to Automotive Acoustic Testing
IAC Acoustics can offer a complete turnkey service for the provision of automotive acoustic test facilities. With numerous projects around the world, each with very specific requirements, IAC Acoustics can offer a central contact point for a new facility or overhaul and refurbishment of existing buildings.
The IAC turnkey service includes initial design concepts, all the way through to project management, testing and final commissioning of a facility. By opting for a turnkey service, this enables IAC to focus on delivering the optimum acoustic facility by designing a building which is fit for purpose, utilises the available space effectively and performs to the specified criteria.
With over 60 years experience in providing acoustic test facilities, IAC Acoustics has built up extensive relationships with international dynamometer companies to offer your preferred choice of supplier.
Vehicle Semi-Anechoic Chambers (VSACs) are typically used for the measurement of inner and outer noise & vibration of a car with 2WD or 4WD, typically during run-up and coast down and at constant speeds, including the measurement of intake and exhaust, engine compartment, steering wheel and seat rail vibrations.
Road traffic noise is a main contributor to environmental noise, thus, it is intended to be reduced and limited by legislation in order to increase health and life quality.
Vehicle pass-by noise tests are conducted according to the international standard ISO 362, which quantifies the noise emission of a vehicle in an urban traffic environment, by testing on an outdoor track.
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.
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.
