  • Publication number: 20240422486
    Abstract: A hearing system includes an input unit for obtaining an input audio signal, a processing unit for processing the input audio signal to obtain an output audio signal, and an output unit for outputting the output audio signal. The processing unit includes a first audio signal path having a noise cancellation unit for obtaining a target audio signal from the input audio signal, the noise cancellation unit comprising a neural network for contributing to obtaining the target audio signal, a second audio signal path bypassing the noise cancellation unit, and a mixing unit for mixing the target audio signal from the first audio signal path with audio signals from the second audio signal path for obtaining the output audio signal, wherein the second audio signal path comprises a delay compensation unit for compensating processing times in the first audio signal path.

  • Publication number: 20240334137
    Abstract: A hearing system comprises at least one hearing device having an input unit for obtaining an input audio signal, a processing unit for processing the input audio signal to obtain an output audio signal, and an output unit for outputting the output audio signal. The hearing system further comprises an estimation unit for estimating a signal property of the input audio signal. The processing unit comprises a first audio signal path having a noise cancellation unit for obtaining a target audio signal from the input audio signal, a second audio signal path bypassing the noise cancellation unit and a mixing unit for mixing the target audio signal with audio signals from the second audio signal path for obtaining the output audio signal. The mixing unit is configured to adjust the contribution of the target audio signal to the output audio signal.
