Patent ID: 11930331

Abstract:
A method, an apparatus and a device for processing sound signals are provided in the present application. The method comprises: receiving a first sound signal through a first sound reception apparatus and a second sound signal through a second sound reception apparatus respectively; the first sound reception apparatus and the second sound reception apparatus have a corresponding reception delay constant therebetween; performing delay processing on the first sound signal according to the reception delay constant at each signal processing time to acquire a signal correlation coefficient between the first sound signal after the delay processing and the second sound signal; detecting whether the first sound signal and the second sound signal include a coherent noise signal according to the signal correlation coefficient between the first sound signal after the delay processing and the second sound signal; filtering out the coherent noise signal from the first sound signal and the second sound signal when the coherent noise signal is included in the first sound signal and the second sound signal to acquire and output a target sound signal at a corresponding signal processing time.
