Abstract (en)
[origin: EP0989775A1] The hearing aid has a microphone (10) for direct sound acquisition and for generating a corresponding electrical tone signal., at least one other signal transducer (11,12) operating on a different principle for alternative generation of a tone signal and a switch (20) for outputting one of the tone signals depending on a monitoring device (25) for subsequent amplification and output via a loudspeaker (64). The monitoring device monitors all tone signals, checks them for signal quality and selects the best signal using the switch.
