A hearing prosthesis circuit includes a power source, a first amplifier coupled to the power source, and a second amplifier coupled to the power source. The circuit also includes a stimulation component coupled to the first amplifier and the second amplifier. The stimulation component is configured to provide an output in accordance with an electrical signal that includes audio data. Further, the circuit includes a controller coupled to the first amplifier and the second amplifier. The controller is operable in accordance with a first operational setting to use the first amplifier to provide the electrical signal to the stimulation component and the controller is also operable in accordance with a second operational setting to use the second amplifier to provide the electrical signal to the stimulation component. Generally, the first amplifier provides greater signal amplification of the audio data than the second amplifier.

A method for the identification of an earpiece belonging to one of a plurality of earpiece types in a hearing aid system includes supplying an electrical input signal to the earpiece for sound output. The input signal is a primary signal, and a secondary signal that depends on the input signal is generated on the basis of the sound output. The secondary signal is captured by a sensor which generates an electrical sensor signal depending on the secondary signal. A phase measurement is furthermore carried out by determining a phase difference between the input signal and the sensor signal. The earpiece is then identified by assigning the earpiece to one of the plurality of earpiece types on the basis of the phase difference. A corresponding hearing aid system and an earpiece set are also provided.

A circuit and a receiver comprising the circuit, the circuit is able to either feed a received signal directly to the receiver coil or amplify the signal before transmission to the coil. The circuit receives a supply power and amplifies the input signal if the supply power exceeds a threshold value.

The present application discloses hearing prostheses with two modes of operation and methods for operating the prostheses. In the first mode of operation, a hearing prosthesis receives a microphone input and produces an output based on the microphone input. In the second mode of operation, the hearing prosthesis may detect an accessory input signal and switch to an accessory input mode. The second mode of operation may produce an output that is based at least in part on the accessory input signal. Some embodiments may include detecting an accessory input signal with a detector. In response to detecting an accessory input signal, the hearing prosthesis may switch to an accessory operation mode. When the accessory input signal is not detected, the hearing prosthesis may operate in microphone operation mode.
