  • Patent number: 10028064
    Abstract: The present application discloses a hearing prosthesis configured to alert a user of the presence of sound while operating in a sound awareness mode of operation. When a user of the hearing aid removes the external sound processor and microphone, traditionally, a hearing prosthesis does not produce any audio stimulus. Here, the systems and methods will alert a user to sounds in his or her environment when the external sound processor and microphone are decoupled from the internal components of the hearing prosthesis. In some embodiments, the hearing prosthesis may have an acoustic receiver that is implanted in the recipient. The implanted acoustic detector may be used to detect an aspect of a sound above a threshold level. The threshold may be chosen so the detected sound is a loud sound such as a fire alarm.

  • Patent number: 10015605
    Abstract: A hearing prosthesis system includes a processor arranged to communicate a stimulation signal to a vibration stimulator of a first hearing prosthesis. The processor receives an indication of a measured input signal from a first transducer of a second hearing prosthesis. A processor calculates a feedback associated with the stimulation. The processor may also be further configured to adjust a gain table or an input to a feedback reduction algorithm in response to the calculated feedback. Additionally, the processor of the hearing prosthesis system may also be arranged to communicate a second stimulation signal to a vibration stimulator of the second hearing prosthesis. The processor receives an indication of a measured input signal from the first hearing prosthesis. Further, the processor calculates a second feedback associated with the second stimulation.

  • Patent number: 10015602
    Abstract: Attenuation covers are used to reduce the amplitude of input signals at a microphone or other sound-receiving component of an auditory prosthesis. The auditory prosthesis detects distortion present in the output signal from sound processing components and notifies a recipient that an attenuation cover is recommended or desirable. Use of the cover can provide a clearer output signal to the recipient, so as to improve the recipient experience. Such covers can be particularly useful in environments where the input sound signals exceed the dynamic range of the auditory prosthesis.

  • Patent number: 9986350
    Abstract: A method performed by a device includes generating a first signal in accordance with a first set of one or more operational settings, and determining whether the signal has an acceptable data integrity. If the device determines that the signal has an acceptable data integrity, the method includes maintaining a configuration of the device with the first set of one or more operational settings. If the device determines that the signal does not have an acceptable data integrity, then the method includes automatically configuring the device with a second set of one or more operational settings. The configuration of the device ith the first set of one or more operational settings is associated with greater power efficiency than the configuration of the device with the second set of one or more operational settings.

  • Patent number: 9962293
    Abstract: An implanted microphone is provided that allows for isolating an acoustic response of the microphone from vibration induced acceleration responses of the microphone. The present invention measures the relative motion between a microphone diaphragm, which is responsive to pressure variations in overlying media caused by acoustic forces and acceleration forces, and a cancellation element that is compliantly mounted within a housing of the microphone, which moves primarily in response to acceleration forces. When the microphone and cancellation element move substantially in unison to acceleration forces, relative movement between these elements corresponds to the acoustic response of the microphone diaphragm. This relative movement may be directly measured using various optical measuring systems.
