A method for determining a noise reference signal for noise compensation and/or noise reduction

摘要

The invention provides a method for determining a noise reference signal for noise compensation and/or noise reduction, comprising the steps of: receiving a first audio signal on a first signal path and a second audio signal on a second signal path, filtering the first audio signal using a first adaptive filtering means to obtain a first filtered audio signal, filtering the second audio signal using a second adaptive filtering means to obtain a second filtered audio signal, and combining the first and the second filtered audio signal to obtain the noise reference signal, wherein the first and the second adaptive filtering means are adapted such as to minimize a wanted signal component in the noise reference signal.
