Abstract (en)
[origin: US2016219381A1] A method performs noise suppression in hearing aids. A step of the method involves a first audio signal being split into a plurality of essentially disjunct frequency bands. A further step of the method involves a reference band being selected from the plurality of frequency bands, which reference band has an establishable first component of a speech signal. Another step involves a correlation between the reference band and a first frequency band being ascertained. A further step involves a value that indicates a second component of a speech signal in the first frequency band being ascertained on the basis of the correlation. Another step of the method involves a noise suppression being set in the first frequency band on the basis of the ascertained value.
