Abstract: A hearing aid device is provided. The hearing aid device comprises: an input unit configured to receive an acoustical input and transform it into an electrical input signal; a signal transforming unit coupled to the input unit and configured to process the electrical input signal to obtain an electrical output signal; a stimulation unit configured to generate a stimulation signal for acoustic coordinated reset neuromodulation therapy; an output unit configured to transform at least one of the electrical output signal and the stimulation signal into an acoustical output.
