The audio system comprises e.g. a microphone for capturing an audio signal, an audio signal processor for adaptation of the audio signal and a receiver for generation of an audible signal. According to an embodiment of the invention, a noise signal is injected into the audio signal path between the microphone and the receiver and used for estimating acoustical feedback, the noise signal being generated by the following steps:    The invention may e.g. be used in a hearing aid, a headset or a pair of headphones."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Generation of probe noise in a feedback cancellation system","description":"The invention regards a scheme for generating a probe noise signal to be used in an anti feedback system of an audio system.
