An auditory device according to one embodiment includes a processing unit configurable to determine a noise estimate and a measure for one of a plurality of samples of an audio signal. The measure relates to an upper volume bounds. The processing unit is configured to apply at least one rule using the noise estimate and/or the measure to identify an input dynamic range for mapping the audio signal to a corresponding stimulation signal.

Systems and methods for altering the input dynamic range of an auditory device

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

The present application discloses systems and methods to analyze feedback path information during a fitting session. In accordance with one embodiment, a method is provided and includes during a fitting session, calculating a feedback gain margin of a hearing prosthesis by causing the hearing prosthesis to receive a test signal, output an output signal based on the test signal, and receive a feedback signal based on the output of the output signal, the test signal being configured to test a different parameter of the hearing prosthesis.

Hearing prosthesis fitting incorporating feedback determination

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.
