A method including obtaining data based on a current and/or anticipated future state of a hearing prosthesis and adjusting a set gain margin of the hearing prosthesis based on the current or anticipated future state of the hearing prosthesis.

Prosthesis state and feedback path based parameter management

The present invention relates to recipient fitting of a hearing device. An embodiment of the present invention determines the transmission loss for sound applied to the recipient by the hearing device. Separate gains are then determined for compensating for the determined transmission loss and the measured hearing loss of the recipient. For example, in an embodiment, the hearing device may compensate for transmission losses in a 1:1 manner (i.e., the transmission loss in 100% compensated for). The hearing device may apply a different gain to compensate for the hearing loss, such as a gain that is a fraction (e.g., 33-55%) of the measured hearing loss.

Fitting of hearing devices

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.

Fitting a bilateral hearing prosthesis system

A sub-cranial vibratory stimulator that at least partially bypasses a recipient's skull bone and delivers vibration to fluid within a recipient's skull bone. The sub-cranial vibratory stimulator comprises an actuator that is configured to be implanted beneath a recipient's skull bone. The actuator transfers vibration to the fluid within the recipient's skull without first passing through the skull bone. The actuator is also substantially mechanically decoupled (isolated) from the recipient's skull bone.

Sub-cranial vibratory stimulator

A prosthetic support, including a structure configured to apply a clamping force to a head of a recipient while extending about a back of at least one of a head or neck of the recipient such that output generated by a device supported by the structure is directed into skin of the recipient at a location behind an ear canal of the recipient that covers the mastoid bone of the recipient.

Bone conduction device support

A method includes programming a sound processor to apply frequency shifting on a stimulation signal to generate a frequency shifted stimulation signal. The frequency shifting depends on one or more of a decibel level of a received sound signal, a hearing loss level associated with generating the stimulation signal, attenuation of an output based on the frequency shifted stimulation signal, or operating a hearing prosthesis in a single sided mode or a bilateral mode. The method includes receiving a sound signal, generating the stimulation signal from the sound signal, applying the frequency shifting to the stimulation signal to generate the frequency shifted stimulation signal, and generating, by an actuator of the hearing prosthesis, the output based on the frequency shifted stimulation signal, wherein the output is configured to be perceived as sound.

Signal processing for hearing prostheses

A method and system for automatically configuring a medical device that is at least partially implanted in a human recipient and that includes a transducer arranged to stimulate a physiological system of the recipient, such as a middle-ear implant for instance. The energy level of a signal provided to drive the transducer is progressively increased until there is a threshold electrical change indicative of a threshold change in impedance of the transducer. In the context of a middle-ear implant, for instance, the threshold electrical change indicative of the threshold change in impedance of the transducer may be indicative of the acoustic reflex. The energy level of the signal at that point is then used as a basis to set an operational parameter of the medical device, such as a comfort-level of the middle-ear implant for instance.

Method and system for configuration of a medical device that stimulates a human physiological system

The present application discloses systems, methods, and articles of manufacture for determining prescription rules for a hearing prosthesis. A method in accordance with the present disclosure includes identifying a threshold hearing level and an uncomfortable loudness level for a channel of a hearing prosthesis. In one example, the threshold hearing level and the uncomfortable loudness level are determined in response to a stimulation signal generated utilizing the hearing prosthesis in situ on a recipient. In the present example, the stimulation signal corresponds to the channel of the hearing prosthesis. The method further includes developing a prescription rule based on the threshold hearing level and the uncomfortable loudness level. Generally, the prescription rule includes at least one of a linear compression scheme and a wide dynamic range compression scheme.

Acoustic prescription rule based on an in situ measured dynamic range

A device includes a sound input element for receiving a sound signal and converting the sound signal into an electrical signal. The device also includes an actuator and a sound processor for processing the electrical signal to generate a stimulation signal. The sound processor is configured to apply frequency shifting on the stimulation signal to generate a frequency shifted stimulation signal and to apply the frequency shifted stimulation signal as an output from the device. The frequency shifting can be triggered by detecting that the stimulation signal is associated with frequencies above an output limit of the device for a recipient and/or the stimulation signal can be applied as vibration.

A hearing prosthesis comprising an external component having an integrated user interface, a sound processor configured to process received sounds based on predefined fitting data, and an on-board fitting system configured to set the fitting data in response to control inputs received via the integrated user interface.
