Programmable hearing aid with automatic adaption to auditory conditions

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.

Digital programming device for hearing aids

Digitally programmable, single-channel and multi-channel hearing aids of various manufacturers and/or hearing aids having different acoustic characteristics can be set and adjusted with the programming device of the invention. The programming device includes a microcontroller, main memories, interchangeable company program modules with plug-in locations, and a master program module with corresponding plug location. A display is also provided for the programming device.
