Programmable hearing aid operable in a mode for tinnitus therapy

A programmable hearing aid comprising:

• an acoustoelectrical input transducer which emits an electrical analog input signal;
• an analog-to-digital converter which converts said analog input signal into a digital input signal;
• a digital signal processor supplied with said digital input signal, said digital signal processor having a signal path therein traversed by said digital input signal wherein said digital input signal is processed to produce a processed signal, said signal path having a plurality of signal taps at which tapped signals are respectively obtained;
• a manually actuatable control element connected to said digital signal processor and, when actuated, supplying a first control signal thereto;
• said digital signal processor including a signal analyzer which generates a second control signal dependent on at least one of said first control signal and said tapped signals;
• said digital signal processor including means for generating a tinnitus therapy signal comprising a signal source which emits a signal source output, and means for varying said signal source output comprising means for at least one of spectrally shaping, time modulating and level influencing said signal source output dependent on said second control signal to generate said tinnitus therapy signal;
• said digital signal processor including means for combining said processed signal and said tinnitus therapy signal to produce a processor output signal;
• a digital-to-analog converter for converting said processor output signal into an electrical analog output signal;
• and
• an electroacoustic output transducer supplied with said analog output signal.
