Noise cancellation sensor improves safety, driving experiences

January 28, 2021  Stephen Law

MOLEX Accelerometer-based Road Noise Cancelling (RNC) sensor joins family of automotive Active Noise Cancellation (ANC) devices that play a critical role in combatting unwanted road, wind and HVAC car noise, while reducing low-frequency sounds that increase driver fatigue. Family of ANC accelerometer and microphone sensors use Analog Devices’ Automotive Audio Bus (A2B) technology to ensure delivery of high-fidelity audio while significantly reducing cabling complexity, costs and weight. By pairing its sensors with the A2B network, firm transmits noise signals to the processing unit in less than two milliseconds. The sensors include integral connectors and are daisy chained to simplify integration while providing up to a 30% reduction in cable weight. Derived from firm’s Mini50 Connector family, connectors provide up to 50% space savings over traditional USCAR 0.64 connectors.
