Binaural hearing device system with binaural active occlusion cancellation

A binaural hearing system comprising a first hearing device and a second hearing device, each of which comprises:

• an input transducer for provision of an input transducer audio signal;
• a transducer audio signal processor configured to process the input transducer audio signal into a processed input transducer audio signal;
• an ear canal microphone for provision of an ear canal microphone audio signal based on sound received inside an ear canal of a user wearing the binaural hearing device;
• an ear canal audio signal processor configured to process the ear canal microphone audio signal into a processed ear canal audio signal;
• a first signal combiner configured to combine the processed input transducer audio signal with the processed ear canal audio signal to obtain an output transducer audio signal;
• a signal level detector configured to determine a signal level of (1) the output transducer audio signal or (2) an audio signal included in formation of the output transducer audio signal, wherein the signal level detector is configured to provide an output signal based on the determined signal level;
• and
• an output transducer configured to provide an acoustic sound signal for emission towards an eardrum of the user based on the output transducer audio signal;
• wherein the binaural hearing system further comprises a binaural excessive level detector connected to the signal level detector of the first hearing device and the signal level detector of the second hearing device, and wherein the binaural excessive level detector is configured to output (1) a first control signal for the ear canal audio signal processor of the first hearing device and (2) a second control signal for the ear canal audio signal processor of the second hearing device, based at least in part on the signal level determined by the signal level detector of the first hearing device and/or the signal level determined by the signal level detector of the second hearing device;
• and
• wherein the ear canal audio signal processor in the first hearing device is configured to attenuate the ear canal microphone audio signal in the first hearing device based on the first control signal, and/or the ear canal audio signal processor in the second hearing device is configured to attenuate the ear canal microphone audio signal in the second hearing device based on the second control signal.
