Title:
NOISE DETECTION METHOD, AND TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/161429
Kind Code:
A1
Abstract:
A noise detection method, and terminal apparatus, configured to detect a noise energy level in a signal. The noise detection method comprises: computing, according to a first formula, an amplitude spectrum of each audio signal frame (103); determining, according to candidate noise frequencies, a noise frequency (106), said candidate noise frequencies being obtained by means of performing cepstral analysis on said audio signal frame (104, 105); and computing, according to the noise frequency, the amplitude spectrum, and a predetermined computing algorithm, a value of a noise energy level of said audio signal frame (107).
