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
  • All common acoustic plots available:
    - Colourmaps, waterfall, order tracking, various 2D SPL plots
    - Frequency resolution/range user-defined to closely resemble plots from 
      lab analysis systems    
    - Order/frequency cursors aid identification of problems
  • Generates audio files for sound quality assessment with flow noise and Doppler effects
    - Production V8 even firing order
    - Production V8 uneven firing order
    - F1 in car
    - F1 passing
  • Frequency network view of system pressure nodes and antinodes
  • Cross plotting of results from different models
  • WaveBuild3D
    - Creation and fully automatic meshing of intake and exhaust system
      components using a user friendly 3D solid modeler
    - Library of primitive volumes, planar and duct elements
    - Direct import of shell geometry from all leading CAD packages
  • WaveMesher
    - Import and repair of STL geometry
    - Model meshing using a range of easy to use discretisation tool
