Abstract
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.
Claims34
A method of processing an audio signal at an auditory device, comprising:
- determining a measure and a noise estimate of the audio signal;
- adjusting, based on the measure and the noise estimate, at least an upper portion of an input dynamic range of the auditory device;
- and
- determining an output representative of a stimulus level based on the measure, the noise estimate, and a static input.

An auditory device, comprising:
- a processing unit configured to:
- determine a measure of an upper amplitude of the audio signal over a preceding time period and a noise estimate of the audio signal for at least one of a plurality of samples of an audio signal;
- and
- identify, based on the noise estimate and the measure, an input dynamic range for mapping the at least one of the plurality of samples of the audio signal to a corresponding stimulation signal.
