Patent ID: 8385572

Claim:
A method for reducing a noise in a hearing apparatus, comprising: picking up an input signal; modeling the input signal with a noise reduction algorithm based on data models having model parameters, the data models comprising a wanted signal model and a noise signal model, and providing by the noise reduction algorithm a signal statistic based on the modeling; computing a quality metric Q representing a current quality of noise reduction achieved by the noise reduction algorithm from the input signal and the signal statistic; based on a threshold of the quality metric: (i) logging in a data logging unit data comprising the input signal, and the model parameters and the quality metric from the noise reduction algorithm; (ii) training for improved data models using the logged data; (iii) changing the data models comprising one or both of the wanted signal model and the noise signal model with the improved data models as a function of the signal statistic based on the logged quality metric Q; and producing an output signal having reduced noise based on the noise reduction algorithm based on the data models.
