WAVE - acoustics and noise

WAVE applications

Acoustics and noise

WAVE is used extensively by manufacturers all over the world for the acoustic prediction of intake and exhaust noise. Whether developing a more cost effective exhaust system or creating a tailored exhaust sound, WAVE has unmatched capability for acoustic modelling.

WAVE allows the simulation of static and pass-by noise tests, the location of intake and exhaust resonances and, most importantly, the simultaneous prediction of both engine performance and sound pressure level.

Key features

  • Prediction of radiated intake and exhaust noise with source interaction and flow noise effects fully captured
  • Moving sources and/or microphones with accurate Doppler shift
  • Add custom noise transfer functions to predict interior noise
  • Full control over data acquisition and signal processing settings
