1. A hearing aid comprising:
- an acousto-electrical transducer for picking up an incoming acoustical signal and for converting said acoustical signal into an electrical signal;
a control device supplied with said electrical signal for processing said electrical to produce a processed signal, including analyzing said electrical signal to detect a noise signal therein originating from externally interfering electromagnetic disturbances, and thereby obtaining an analysis result and automatically setting at least one control parameter selected from the group of transmission parameters and acoustic programs, dependent on said analysis result; and
an electro-acoustical transducer supplied with said processed signal for producing an acoustic output therefrom.

Abstract
For improving the automatic switching and control of hearing aid devices in view of respective auditory situation, the acoustic signal picked up by the hearing aid device is analyzed for noise signals. The control of the hearing aid device then ensues on the basis of the analyzed noise signals. Individual transmission parameters or entire hearing programs of the hearing aid device can be controlled or switched.
