Abstract
The disclosure relates to a method of operating a hearing device configured to be at least partially inserted into an ear canal of a user, the method comprising receiving an input audio signal; amplifying the input audio signal; and outputting, by an output transducer included in the hearing device, an output audio signal based on the amplified audio signal so as to stimulate the user's hearing.

A method of operating a hearing device configured to be at least partially inserted into an ear canal of a user, the method comprising:
- receiving an input audio signal;
- amplifying the input audio signal;
- outputting, by an output transducer included in the hearing device, an output audio signal based on the amplified audio signal so as to stimulate the user's hearing;
- determining, based on an estimate of a measure of a Real Ear Occluded Gain (REOG) and a measure of a Real Ear Aided Gain (REAG), a measure of a Real Ear Reducible Gain (RERG) indicative of an amount by which noise contained in the input audio signal can be attenuated in the amplified audio signal;
- and
- controlling an operation of the hearing device depending on the RERG measure.
A hearing device configured to be at least partially inserted into an ear canal of a user, the hearing device comprising:
- an input transducer configured to provide an input audio signal;
- a processor configured to amplify the input audio signal according to a predetermined transfer function;
- and
- an output transducer configured to output an output audio signal based on the amplified audio signal so as to stimulate the user's hearing,
- wherein the processor is further configured to determine, based on a measure of a Real Ear Occluded Gain (REOG) and a measure of a Real Ear Aided Gain (REAG), a measure of a Real Ear Reducible Gain (RERG) indicative of an amount by which noise contained in the input audio signal can be attenuated in the amplified audio signal;
- and
- control an operation of the hearing device depending on the RERG measure.
