As a professional sound quality solution company, Acoutec found that the emerging automotive active sound quality control solution is actually an interdisciplinary and cross-domain concept. Most of the current professional divisions do not fully cover the basics involved in this concept. Therefore, Acoutec will introduce some basic knowledge points in multiple sessions. With the goal

RNC controller hardware design Hardware design and IC selection need to consider the following key points: The computing power and storage capacity of the main chip IC Number of audio channels and audio stream path Control and troubleshooting System delay Heat dissipation efficiency Whether built-in sound algorithm Installation size total cost RNC controller software design

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
