摘要： The invention regards a method for noise reduction in an audio device whereby an electrical and/or digital signal which represents sound is routed simultaneously through: - a signal analysis path, and- a signal processing path wherein the signal amplification is individually controllable in specific frequency bands by attenuation values derived from the signal analysis path, whereby the signal in the signal analysis path is routed simultaneously through: - a first detector which identifies the presence of speech indicators in the overall signal, and- a second detector which in a predefined number of frequency bands detects the modulation amplitude, and- where attenuation values in each of the predefined frequency bands are calculated based on the combined results of the first detector and the modulation amplitude in the specific frequency band detected by the second detector, - where the attenuation values in the predefined number of frequency bands are routed to the signal processing path in order to attenuate the signal level in corresponding frequency bands.

摘要： The invention relates to a method of enhancing an audio signal in a receiving device. The invention further relates to an audio enhancement device and an audio enhancement system. The object of the present invention is to provide a scheme for improving signal quality of an audio signal received by a listening device. The problem is solved in that the method comprises acoustically propagating a target signal from an acoustic source along an acoustic propagation path, providing a propagated acoustic signal at the receiving device;converting the received propagated acoustic signal to a propagated electric signal, the received propagated acoustic signal comprising the target signal, noise and possible other sounds from the environment as modified by the propagation path from the acoustic source to the receiving device; wirelessly transmitting a signal comprising the target audio signal to the receiving device;receiving the wirelessly transmitted signal in the receiving device;retrieving a streamed target audio signal from the wirelessly received signal comprising the target audio signal;and estimating the target signal from the propagated electric signal and the streamed target audio signal using an adaptive system. An advantage of the invention is that a target signal is enhanced. The invention may e.g. be used in listening devices, e.g. hearing aids, receiving audio sound from a signal source via an acoustic path.
