Molex has introduced an accelerometer-based road noise cancelling (RNC) sensor, the company said in a press release on 27 January. The ANC accelerometer and microphone sensors use Analog Devices' Automotive Audio Bus, which enables the transmission of noise signals to the processing unit in less than two milliseconds, according to the company.
“As the transition to electrified vehicles intensifies, it will become critical to reduce road noise, which today is masked by internal combustion engines. Our long history in the automotive industry uniquely positions Molex to develop powerful, durable sensor technology that captures and cancels road noises while enabling safe and enjoyable driving experiences,” said Carrieanne Piccard, VP and General Manager, Transportation Solutions Business Unit, Molex.
Significance: Molex develops electronics solutions and services for automotive, data communications, consumer electronics, medical, and industrial markets. It offers in-vehicle network cables, connectors, media modules, switches, and gateways. The company has tested and validated the use of its RNC sensor with Silentium's "Active Acoustics" software.
The growth of vehicle electrification will lead to the rise of road noise cancellation technologies. The ANC sensors are designed to be installed on a car's chassis for efficiency.
