An active medical device, including an input receiver configured to receive a frequency-varying input signal, and a functional component that reacts to the input signal and consumes power at a rate dependant on the frequency of portions of the input signal to which the functional component reacts, wherein the active medical device is configured to adjust one or more portions of the input signal corresponding to portions of the input signal where the functional component consumes power at a rate that is greater than that of other portions of the input signal.

A hearing-aid apparatus includes an audio collector, an audio processor, a speaker and an inner-ear implant device. The audio collector collects audio information. The speaker generates a sound wave by reference to the audio information. The sound wave is transmitted to an inner ear of a user. The inner-ear implant device is implanted aside a round window of the user for generating an electrical signal encoded by the audio processor based on the audio information to stimulate high frequency auditory nerve cells of the user with an electrode of the inner-ear implant device. The audio wave sent to the inner ear of and the electrical signal stimulating the auditory nerve cells together form an integrated auditory recognition corresponding to the audio information.

In one embodiment, an audio system can generate a parametrically formulated noise signal which can be mixed with an audio signal or acoustic signal. According to an embodiment, a parametrically formulated noise signal can be configured to have a power spectrum amplitude that is a function of frequency. According to an embodiment, a parametrically formulated noise signal can have a power spectrum amplitude across a range of frequencies that is a function of an individual's hearing thresholds across the range of frequencies.

In one embodiment, an audio system can replace a portion of an audio signal within a first range of frequencies, with an amplitude modulated noise signal comprising frequencies within the first range of frequencies and having a volume envelope corresponding to a volume envelope of the audio signal within a second range of frequencies.

The present invention relates to a receiver unit comprising a plurality of moveable membranes, a motor assembly being adapted to drive a first moveable membrane and one or more successive moveable membranes in accordance with an incoming electrical drive signal, wherein the first and at least one of the successive moveable membranes have different frequency responses in order to enhance the frequency response of the receiver unit. The present invention further relates to a hearing aid instrument comprising the receiver unit.

A hearing aid system includes an electronic device that may be manipulated. A hearing aid is provided and the hearing aid is selectively worn in an ear thereby facilitating the hearing aid to amplify ambient sounds. A noise generator is coupled to the hearing aid and the noise generator is in electrical communication with the electronic device. The electronic device controls operational parameters of the noise generator and the noise generator selectively emits white noise. The noise generator is in electrical communication with the hearing aid such that the hearing aid emits the white noise in conjunction with the ambient sounds. In this way the noise generator enhances a sensitivity threshold of the ear.
