Method and hearing assistive device for handling streamed audio
First Claim
1. A hearing assistive device having an input transducer adapted for converting sound into an audio signal, a processor receiving said audio signal and configured to compensate a hearing loss of a user of the hearing assistive device and to output a compensated audio signal, and an output transducer adapted for converting the compensated audio signal into sound, and further comprising:
- a wireless transceiver enabling audio streaming from an external device to the hearing assistive device;
a sound dosimeter measuring during audio streaming a parameter representative of a sound exposure of the compensated audio signal output by the output transducer; and
a controllable attenuator associated with said processor adapted for applying attenuation to the compensated audio signal;
wherein the attenuator is controlled according to the parameter measured by the sound dosimeter only during said audio streaming from said external device.

Abstract
A hearing assistive device has an input transducer (12) converting sound into an audio signal applied to a processor (14; 65). The processor (14; 65) is configured to compensate a hearing loss of a user of the hearing assistive device and to output a compensated audio signal. An output transducer (16; 65) converts the compensated audio signal into sound. The hearing assistive device (10) further comprises a wireless transceiver (21) enabling audio streaming from an external device (30) to the hearing assistive device, an attenuator (23) associated with said processor (14; 65) applying attenuation to the compensated audio signal, and an audio stream analyzer (22a) classifying the audio stream received via said wireless transceiver. The attenuator (23) is controlled in accordance to the audio stream classification from the audio stream analyzer (22a). The invention further provides a method of operating a hearing assistive device.
