ABSTRACT OF THE DISCLOSURE In a hearing aid comprising an input transducer, processing circuits for useful signals including an output stage and an output transducer, the useful signals are sampled with a sampling frequency before the output stage, are converted into data words, and are also processed in discrete-time fashion. The digital data words are capable of being converted into pulse-duration-modulated signals without being re- converted into analog signals. For this purpose, the processed data words can be read into a counting circuit via at least one input which can be placed into an initial condition with counting pulses after every read-in data word. The output stage is designed as a switching amplifier and is driven with an output signal of the counting circuit.
