Abstract
Provided is a hearing device and method for compensating for a hearing loss. To compensate for the hearing loss, the hearing device and method utilize the gain during feedback in the forward path of a compressive system which, after having reached its steady state in 'closed loop' operation, is equal to the feedback threshold gain. The steady state is reached soon after having applied a low input signal level to the hearing device, which input signal level is below 55 dB SPL (Sound Pressure Level), for example, and would result, for the open loop compressive system, in a larger gain than the feedback threshold gain of the closed loop system, respectively, would result in the maximum possible hearing device gain if maximum possible hearing device gain is below feedback threshold gain. The signal feedback gain is assessed in this steady state.
