An illustrative hearing device includes a battery having a battery voltage, a microphone for transducing sound into an input signal, a processor configured to be operated with an operating voltage and to generate an output signal from the input signal, a speaker for transducing the output signal to an acoustic signal, and a valve. An acoustic effect of the valve is adjustable by applying a valve voltage, wherein the adjustment is controllable by the processor. The hearing device comprises a voltage regulator configured to generate the operating voltage from the battery voltage, wherein the operating voltage is less than the battery voltage and wherein the valve voltage is greater than the operating voltage.

CIC Hearing device () comprising electronics configured to receive an electrical signal as an input signal and generate an output signal provided to a receiver, the electronics including a variable gain amplifier with input buffering circuitry including a compound transistor, the electronics being configured to bias the compound transistor such that a quiescent current associated with the output signal is limited or controlled.

CIC hearing device

A method for detecting and automatically selecting an input signal in a hearing aid in which at least two analog input signals are available, comprises the steps of A hearing aid according to the invention comprises means to perform the above method.

Hearing aid and method for the detection and automatic selection of an input signal

In order to generate a predetermined or predeterminable receiving characteristic of a digital hearing aid having at least two microphones, the analog output of at least one of the microphones ( ) is converted in an analog-digital manner by over-sampling and then is down-sampled. The time delay necessary to adjust the directional characteristics is carried out at the down-sampled signal. The two signals fed from the microphones ( ) to a superposition unit ( ) are level matched.
