Abstract
A device, including an implantable microphone, including a transducer, and a chamber in which a gas is located such that vibrations originating external to the microphone based on sound are effectively transmitted therethrough, wherein the transducer is in effective vibration communication with the gas, wherein the transducer is configured to convert the vibrations traveling via the gas to an electrical signal, the chamber and the transducer correspond to a microphone system, wherein the chamber corresponds to a front volume of the microphone system, and the transducer includes a back volume corresponding to the back volume of the microphone system, and the implantable microphone is configured to enable pressure adjustment of the front and/or back volume in real time.
Claims22
A device, comprising:
- an implantable microphone configured to be implanted in a mastoid region of a recipient, including:
- a transducer, and
- a chamber in which a gas is located such that vibrations originating external to the microphone based on sound are effectively transmitted therethrough, wherein
- the transducer is in effective vibration communication with the gas, wherein the transducer is configured to convert the vibrations traveling via the gas to an output signal,
- the chamber and the transducer correspond to a microphone system, wherein the chamber corresponds to a front volume of the microphone system, and the transducer includes a back volume corresponding to the back volume of the microphone system, and
- the implantable microphone is configured to enable a volumetric size change of at least one of the back volume at a location outside of the transducer or the front volume at a location outside the transducer.
A hearing prosthesis, comprising:
- a microphone system, wherein
- the hearing prosthesis is configured to evoke a hearing percept based on at least some frequencies captured by the microphone system and adjust a transfer function of the hearing prosthesis to accommodate for changes in an environment of the hearing prosthesis, and
- the hearing prosthesis is configured to adjust a feature of the hearing prosthesis in a timeframe slow enough that the adjustment to the feature accommodates the microphone system.
