A hearing aid has a microphone, a signal processing chain having a series of signal processing levels, a signal output transducer, a memory in which at least one set of parameters allocated to a hearing situation is stored that enables matching of the parameters of the signal processing stages to the hearing impairment of the wearer. Adjustment elements independent of the signal processing stage are provided, and the allocation of the adjustment elements 9 to the individual signal processing stages can be selectively determined. Adjustment of the respective signal processing stages can be accomplished in a non-computerized manner using the adjustment elements, thereby allowing the hearing aid to be used in countries and regions wherein personal computers are not readily available or accessible.
