Abstract
For continuous, automatic and autonomous adaptation of its transmission characteristics, a hearing aid includes in addition to a microphone, earphone and amplifier/transmission circuit, a first data memory in which audiometric data are stored, a second data memory in which hearing aid characteristics are stored, a third data memory in which algorithms are stored, a signal analysis unit that determines control signals dependent on input quantities characteristic of the current ambient situation, and also includes a data processing unit, the data processing unit offering hearing aid setting data for the amplifier/transmission circuit from the data of the data memories and from the control signals of the signal analysis unit, so that the transmission characteristics of the amplifier/transmission circuit can be automatically determined from the edited audiometric data, hearing aid characteristics, prescribable algorithms and the input quantities characteristic of the current ambient situation.
