In-vehicle wide-narrow band mixed noise control method, device, equipment and medium

Abstract

The invention relates to an in-vehicle wide-narrow band mixed noise control method, device and equipment and a medium, and belongs to the field of noise control. The method comprises the following steps: dividing an area in a vehicle, collecting a sound source in the vehicle, performing short-time framing processing on the sound source in the vehicle to obtain a sound source signal in the vehicle, and dividing the sound source signal into a silent section signal and a noisy section signal; performing enhancement operation on the noisy-segment signal to obtain an enhanced noisy-segment signal; identifying the enhanced noisy segment signal to obtain a wide-narrow band mixed noise signal and a non-noise signal; transmitting the wide-narrow band mixed noise signal to a control end and generating a control noise signal to carry out active noise control; a control noise audio is generated from the control noise signal. According to the method, the in-vehicle wide-narrow band mixed noise is controlled in a regional, flow and efficient manner.
