ABSTRACT

In real life, there are more and more outdoor positioning fields, which are higher in the quality of multi-source collection, separation of multiple sound sources, positioning of multiple sound sources, accuracy of positioning, volume and power consumption of equipment. Claim. In order to obtain a high-quality sound source in a noisy background environment, this paper proposes a dual-microphone noise reduction system to cope with indoor and outdoor complex noise environments, combining time domain and frequency domain processing, and spectral noise reduction and blind source separation noise reduction. Two methods are used to eliminate noise to improve the accuracy and quality of the sound source.
