Active Noise Cancellation

  • Engine Order Cancellation (EOC) algorithm uses engine RPM signal and sound level measured via microphones to create noise cancelling sound wave  

  • High-Frequency Road Noise Cancellation (HF-RNC) algorithm reduces road and tire noise up to 1000 Hz.

  • Heating, Ventilation, and Air Conditioning Noise Cancellation (HVNC) reduces heating and cooling fan and compressor noises. 

  • Virtual Microphone Technology (VMT) predicts noise levels at occupant ear level more accurately  

  • ​TrueAudio preserves audio quality and eliminates only unwanted noises ​

Electronic Sound Synthesis (ESS)

  • Creates personalized and brand defining sounds both inside and outside the vehicle cabin  

  • Internal sound synthesis (iESS) personalization controls allow drivers to adjust vehicle sounds 

  • External sound synthesis (eESS) warns pedestrians by generating a unique audio signature  

  • Ensures EVs and hybrids meet all regulatory requirements  

Sound2Target (S2T)
  • Combines active noise cancellation and sound synthesis to remove unwanted noise and augment the cabin with targeted sound experiences​
