WAVE - acoustics and noise

WAVE is used extensively by manufacturers worldwide for acoustic prediction of intake and exhaust noise. Whether developing a more cost-effective exhaust system or creating a tailored exhaust sound, WAVE as unmatched capability for acoustic modelling.
WAVE enables the simulation of stationary and pass-by noise tests, the location of intake and exhaust resonances and, most importantly, simultaneous prediction of engine performance and sound pressure levels.
