  • Patent number: 10237664
    Abstract: Disclosed herein are methods, systems, and devices for discontinuously recording audio input representative of an audio environment. The audio environment can be an environment of a recipient of a hearing prosthesis and the discontinuously recorded audio input can be used to characterize the audio environment of the recipient, to control settings of the hearing prosthesis, or to provide some other application. Discontinuously recording the audio input can provide a recording that characterizes the audio environment of the recipient while protecting the privacy of individuals speaking nearby the recipient. Discontinuously recording the audio input may include recording discontinuous time segments of the audio input such that the semantic content of speech within the audio input, the identity of speakers in the audio input, or other private information present in the audio input is masked.

  • Patent number: 10225671
    Abstract: Presented herein are techniques for providing tinnitus relief to recipients of a hearing prosthesis. In accordance with embodiments presented herein, a hearing prosthesis comprises a tinnitus relief system that is configured to generate a tinnitus masker signal that comprises a plurality of discrete (separate) components. The tinnitus relief system is configured to inject the components of the tinnitus masker signal directly into a sound processing path so that the masker components are combined with different processed portions of a channelized sound signal. The channelized sound signal and the components of the tinnitus masker signal are used to generate one or more output signals for use in compensation of a hearing loss of a recipient of the hearing prosthesis.

  • Patent number: 10194254
    Abstract: A bone conduction device utilizes discrete retention magnets to secure both a sound processor housing and a vibration actuator to a head of a recipient. Only an electrical lead connects the sound processor housing and the vibration actuator. As such, the sound processor housing and the vibration actuator are mechanically separated. This mechanical separation helps reduce or eliminate vibration transmission between the two components, thus reducing feedback caused by the vibrations.
