Hearing aid adapted for detecting brain waves and a method for adapting such a hearing aid
First Claim
1. A hearing aid comprising an amplifier, an input transducer, an output transducer and a signal processing device, said amplifier and said signal processing device being connected;
- at least two electrodes adapted for detecting electrical signals such as brain waves, the at least two electrodes being connected to a differential amplifier, which in turn is connected to the signal processing device; and
means for modifying the operation of said hearing aid to obtain optimum intelligibility of the particular part of an acoustic image, without the user needing to consciously act to adapt the hearing aid, in response to the detected signals.

Abstract
A hearing aid comprises an amplifier (303, 309, 317), an input transducer (301), an output transducer (824) and a signal processing device (825). The amplifier (303, 309, 317) and the signal processing device (825) are connected. The hearing aid further comprises at least two electrodes (201-205) adapted for detecting electrical signals such as brain waves, the at least two electrodes (201-205) being connected to a differential amplifier (303, 309, 317), which in turn is connected to the signal processing device, and means for modifying the operation of said hearing aid in dependence of the detected signals. The invention further provides a method for adaptation of a hearing aid.
