    Abstract: Disclosed herein are embodiments of a hearing aid. The hearing aid includes an input unit configured to convert a sound in an environment of the hearing aid to at least one electrical input signal representative of the sound. The hearing aid includes a signal processor. The signal processor is configured to determine, based on the at least one electrical input signal, whether an origin of the sound is below a distance threshold. The signal processor is configured to, in accordance with the origin being below the distance threshold, attenuate the at least one electrical input signal. The signal processor is further configured to determine, based on the at least one electrical input signal, whether the origin is above a far-distance threshold, and in accordance with the origin being above the far-distance threshold, attenuate the at least one electrical input signal.
