Abstract
Abstract A remote-controllable, programmable hearing aid system, including of a hearing aid (2) with incorporated amplifier and with a signal processing circuit whose transmission characteristic can be determined at any time by a set of control parameters, and an external control unit (1) with a transmitter for wireless transmission of control parameters to the hearing aid. A receiving circuit for receiving the control parameters is located in the hearing aid. This system is characterized in that an input device (3) is provided for input of data/information, and a data processing device (4) is provided for derivation of control parameters from the audiometric data/information for transmission from the control unit to the hearing aid.
