Abstract
Official abstract text for this publication.
A method of noise suppression in a hearing aid system by providing an improved noise estimate derived from the difference of a first digital audio signal provided by a first input transducer and an adaptively filtered second digital audio signal provided by a second input transducer. The invention further provides a hearing aid ( 100, 200 ) and a hearing aid system ( 300 and 400 ) adapted for improving noise suppression in accordance with this method.
First claim
Opening claim text (preview).
We claim: 1. A method of processing signals in a hearing aid system comprising the steps of: providing a first input signal representing the output from a first input transducer of the hearing aid system; providing a second input signal representing the output from a second input transducer of the hearing aid system; using a time-varying adaptive filter to filter the first input signal, hereby providing a filtered first input signal; subtracting the filtered first input sign…
