Patent ID: 8369551

Claim:
A hearing aid having a microphone and an amplification unit for amplifying microphone signals, comprising: a radio reception unit for wireless reception of a modulated and/or coded audio signal, comprising: an estimating device to estimate a reception quality of the received modulated and/or coded audio signal; a generating device to generate an acoustic limit signal, a level of the acoustic limit signal increases when the estimated reception quality of the received modulated and/or coded audio signal decreases; a heterodyning device to heterodyne a demodulated and/or decoded audio signal with the acoustic limit signal; and an outputting device to output an audio signal heterodyned with the acoustic limit signal to a hearing aid wearer, wherein the generating device comprises: a second generating device to generate a synthetic room impulse response as a function of the estimated reception quality, such that a convolution of the acoustic limit signal with the synthetic room impulse response produces a resulting limit signal, the resulting limit signal appears louder and therefore closer to the hearing aid wearer when the estimated reception quality of the modulated and/or coded audio signal is poor; and a convolving device to perform an operation of convolving the acoustic limit signal with the synthetic room impulse response.
