An implantable microphone senses a sound signal present at the microphone that includes a sound source component from a sound source external to the patient, and a noise component from internal bone conduction. At least one implantable noise sensing element is located near the microphone to sense the noise component. A filter is controlled by an adaptive algorithm responsive to transform the noise component and outputs a transducer control signal. A bone conduction transducer receives the transducer control signal and generates a corresponding mechanical vibration signal to the skull bone. The adaptive algorithm controls the filter so that the mechanical vibration signal of the bone conduction transducer offsets the noise component sensed by the at least one noise sensing element so as to minimize the noise component sensed by the implantable microphone.

  • Patent number: 11115750
    Abstract: A system, device and method for assessing a fit quality of an earpiece while in use in a noisy environment. The earpiece having an external microphone for capturing an outer-ear audio signal and an internal microphone for capturing an inner-ear audio signal. The fit quality being assessed by estimating a filter according to the captured inner-ear and outer-ear audio signals, and determining a fit quality according to identified coefficients of the estimated filter. A system, device and method for assessing a seal quality of an earpiece while in use in a quiet environment. The earpiece having a loudspeaker for emitting a sound stimulus towards the ear canal and an internal microphone for capturing an audio signal inside the ear canal. The seal quality being assessed by estimating a transfer function according the emitted and captured sound stimulus, and determining at least one seal-quality indicator according to a signal magnitude of the transfer function.

  • Patent number: 11090495
    Abstract: An alert system detects when an auditory prosthesis recipient is wearing her sound processor. When the processor is not worn, the alert system signals a secondary device, such as an accessory, to provide some other form of tactile stimulation to allow the recipient to be made aware of certain auditory stimuli she is not receiving via the auditory prosthesis. Thus, the alert system can effectively “hear” for the recipient. Since many auditory prosthesis recipients are, for all practical purposes, completely deaf without their external sound processors attached and operational, such an alert system increases the recipient's safety, convenience, and quality of life.

  • Patent number: 11083891
    Abstract: The present disclosure relates to compact hearing aids, components thereof, and support systems therefor, as well as methods of insertion and removal thereof. The compact hearing aids generally include a sensor, such as a microphone, an actuation mass, an energy source for providing power to the compact hearing aid, a processor, and an actuator enclosed in a housing that is designed to be inserted through the tympanic membrane during a minimally-invasive outpatient procedure. In operation, the microphone receives sound waves and converts the sound waves into electrical signals. A processor then modifies the electrical signals and provides the electrical signals to the actuator. The actuator converts the electrical signals into mechanical motion, which actuates the actuation mass to modulate the velocity or the position of the tympanic membrane.
