Accurately Predict Automotive Aeroacoustic Noise for a Quieter Ride

To gain a competitive edge as design challenges increase in the automotive industry, accurate prediction of aerodynamic noise is vital. The reduction of wind noise is becoming even more important for hybrid and electric vehicles, as the powertrain noise level is reduced and voice activation systems become more prominent. Fan acoustics, HVAC blower acoustics, compressor noise, duct noise, tire noise and other vehicle sounds must also be minimized for a quieter ride.

Ansys can help solve some of these acoustic design challenges for different operating conditions, including:

  • Noise performance for different design and operating conditions
  • Location and nature of noise sources
  • Effects of active and passive noise treatments
