Road noise development needs to cover every step from design, calibration to mass production, involving multiple departments working together (NVH, electronics, products…) Step 1: Vehicle acoustic environment confirmation Confirm the number of speakers supported by the real car entertainment system and the speaker position. Confirm the frequency response curves of the low, medium and high

RNC technology from Acoutec has several technical features: Adaptive algorithm； High robustness, no pop sound while shock noise happening； High rate of convergence; Integrated sensor signal condition circuit in controller; Wide ANC control frequency range, up to 350 Hz; Performance of RNC has gotten OEMs recognition. Why we need RNC?  Typical noise composition of traditional
