Abstract
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.
