A noise-cancelling earplug assembly is provided, having an ear piece for insertion into the ear canal and a housing removably attached to the ear piece. A hollow core is defined in the housing to receive a sound-selective sound barrier that contains at least one sound filtering element to attenuate sounds reaching the ear drum. An end cap is provided and is attachable to the housing to enclose the sound-selective sound barrier inside the housing. The sound selective sound barrier can be removed from the housing of the earplug and replaced with a different sound selective sound barrier with different sound attenuation characteristics.

A hearing system includes an eye tracking module to detect a sound region of interest; one or more microphone arrays coupled to the eye tracking module and focused on the detected sound region of interest; and one or more amplifiers wirelessly coupled to the one or more microphone arrays and to render sound from the sound region of interest for one or more ears.

A highly effective method for treating refractile tinnitus by repeatedly subjecting a subject having tinnitus to a specific calculated sound comprising a group of related waveforms.

Disclosed technology includes technology for compensating for a balance dysfunction. A system can combine sensory substitution with balance dysfunction suppression. Dysfunctional balance information coming from a recipient's vestibular system is inhibited using stimulation. Balance information (e.g. how the recipient is positioned with respect to gravity, such as rotation along pitch and roll axes) is than passed to another sensory channel (e.g., visual, audible, or tactile sensory channels). Such a system can be implemented with a cochlear implant or another sensory prostheses having balance signals injected into the stimulation signal processing path.

A method for providing information to a user, the method including: receiving an input signal from a sensing device associated with a sensory modality of the user; generating a preprocessed signal upon preprocessing the input signal with a set of preprocessing operations; extracting a set of features from the preprocessed signal; processing the set of features with a neural network system; mapping outputs of the neural network system to a device domain associated with a device including a distribution of haptic actuators in proximity to the user; and at the distribution of haptic actuators, cooperatively producing a haptic output representative of at least a portion of the input signal, thereby providing information to the user.

Aspects of the present invention are generally directed to impedance spectroscopy in an active implantable medical device (AIMD) comprising a component with one or more electrodes. In an embodiment, the AIMD applies a signal at a plurality of frequencies using one or more of the electrodes. Measurements are then obtained for the applied signal to determine impedance(s) at the applied frequencies of the tissue in which the electrodes are located.
