Abstract
The invention relates to a hearing aid with a sound receiver for generating a microphone signal representing a sound wave received and a sound generator for generating a sound depending on a power signal received. The hearing aid has a transmission unit which on the input side is connected to the sound receiver and on the output side to the sound generator and generates a power signal depending on a microphone signal received. The transmission unit modifies a transmission characteristic of the transmission unit as a function of a tag signal received. The hearing aid has a radio frequency detection device connected to the transmission unit, with a spatial detection zone where the radio frequency detection device detects, electromagnetically and in particular inductively, a radio frequency tag and, depending on the radio frequency tag, to generate a tag signal and to output this to the transmission unit.
