<p>A method for classifying sound signals includes: receiving sound signals, and determining the update rate of background noise according to spectral distribution parameters of the background noise and the sound signals; and updating the noise parameters according to the update rate, and classifying the sound signals according to sub-band energy parameters and updated noise parameters. An apparatus for classifying sound signals includes: a background noise parameter updating module, configured to: determine the update rate of background noise according to spectral distribution parameters of the background noise and the current sound signals; and send the determined update rate; and a PSC module, configured to: receive the update rate from the background noise parameter updating module, update the noise parameters, classify the current sound signals according to the sub-band energy parameters and updated noise parameters, and send the sound signal type determined through classification.</p> |
