Mitsubishi Electric has introduced an advanced Active Noise Control (ANC) system – FLEXConnect.ANC – that cancels less predictable and harmonically unrelated road sounds.
FLEXConnect.ANC uses cutting edge technology- XSe ANC -, developed by Mentor Graphics, which minimises engine and road noise to provide a quiet, comfortable environment in the cabin of the vehicle.
FLEXConnect.ANC uses advanced audio processing techniques to adapt rapidly to varying noises from changing road conditions. The audio speakers generate a sound wave at the same amplitude as the originating noise, then adds an inverted wave to the original sound, which creates interference and thus cancels both sound waves.
FLEXConnect.ANC joins Mitsubishi Electric’s existing Ethernet-enabled architectures: FLEXConnect.RSE and FLEXConnect.IVI.
“A precisely tuned audio experience, including advanced ANC, will continue to be a growing differentiator for OEMs – an experience not available from consumer devices or the aftermarket,” said Mitsubishi Electric’s Doug Ray, director of Sales, Quality and Engineering, Audio, Video & Communications.
The solution is a new approach to in-vehicle ANC where inputs aren’t limited to microphones and engine speed, but also include accelerometers for engine order and road noise cancellation. The underlying algorithm is tunable in real time and the results are available instantaneously.
Rainer Oder, general manager, Mentor Automotive Business Unit said of the new technology that:
“The XSe ANC system is an innovative approach to vehicle noise cancellation, and we are pleased that Mitsubishi Electric has chosen our technology for its latest infotainment system. Compared to traditional ANC systems, our solution tackles broadband noise while requiring reduced tuning and calibration effort, overall dramatically shortening our customers’ time to market,” said .
