ABSTRACT:
A wireless hearing aid set consists of a hearing aid and a controller. The hearing aid comprises a microphone, a loudspeaker unit, a variable-gain circuit, a control circuit and a signal receiving unit. The microphone picks up ambient sound waves. The variable-gain circuits adjusts the frequency characteristics and the level of the output signals of the microphone. The loudspeaker unit receives the output signals of the variable-gain circuit and converts the output signals of the variable-gain circuit into corresponding sounds. The control circuit controls the variable-gain circuit on the basis of the output signals of the signal receiving unit. The controller comprises an operating unit and a transmission unit. The operating unit has a plurality of operating devices. The transmission unit transmits control signals corresponding input signals given thereto by operating the operating unit. The controller is provided with indicators for indicating set values, such as the gain of the variable-gain circuit and frequency characteristics of the output signals of the microphone.
