Active noise control manages vehicle cabin noise

 

Industrial partner: Ford Europe

 CHALLENGE

Modern car interior requires low noise level, but also predetermined acoustic profile, e.g. luxury, sporty or special acoustic profile.

 SOLUTION

Vehicle's interior noise is controlled with active noise control (ANC), which changes noise by first measuring it and then modifying the sound with anti-noise. Active Noise Profiling can either attenuate or enhance the noise, based on target profile. The system was developed with advanced simulation tools.

 BENEFIT
  • A predetermined acoustic profile can be created in the car interior.
  • Car interior sound can be tuned to comply with the car operation, e.g. when accelerating , the car interior sound increases giving feedback of the acceleration to driver.
