Abstract
The noise of communication equipment mounted on Vehicle is one of important factors affecting equipment efficiency. Active Noise Control (ANC) technology is applied to noise reduction of the equipment, and a noise reduction mathematics model is built based on accurate noise measurement. An approach to reduce noise based on first-order differential microphone (FDM) array and ANF technology is proposed, which collects and evaluates environmental noise precisely to enhance voice. This approach improves the conversation effects and realizes full fidelity of voice transmission.
