Automatic sound optimizer

摘要

Disclosed herein are systems and methods that help to optimize the sound quality produced when a sound processing mode is enabled in an audio device, such as a hearing prosthesis. When the sound processing mode is enabled, a sound processor in the audio device will create a candidate transformed signal based on a default set of parameters associated with the sound processing mode (i.e. a candidate signal processing function). Further, the sound processor will create a reference transformed signal based on the same enabled sound processing mode, but with a varied set of parameters (i.e. a modified signal processing function). The sound processor will then compare the candidate transformed signal to the reference transformed signal to determine which signal has a higher quality. The device then creates an output based on the higher quality signal.

1. A hearing prosthesis system comprising:
a first receiver arranged to receive an input signal, the input signal having at least one audio attribute; output circuitry for providing an output to a user; and a processor arranged to transform the input signal into a transformed signal and to provide the transformed signal to the output circuitry, wherein the output circuitry provides the output based on the transformed signal, wherein transforming the input signal into the transformed signal comprises (i) applying a candidate signal processing function to the input signal to generate a candidate transformed signal having a first modification of the audio attribute, (ii) applying a reference signal processing function to the input signal to generate a reference transformed signal having a second modification of the audio attribute, the second modification being different than the first modification such that the candidate transformed signal is different than the reference transformed signal, (iii) determining which of the candidate transformed signal and reference transformed signal is better quality, and (iv) selecting as the transformed signal the determined better quality signal and not the determined lower quality signal, wherein providing the transformed signal to the output circuitry comprises providing the determined better quality signal and not the determined lower quality signal to the output circuitry, and wherein the output circuitry provides the output based on the determined better quality signal and not the determined lower quality signal, wherein the processor repeatedly conducts the transforming, wherein, in a first instance of conducting the transforming, the transformed signal is the candidate transformed signal, wherein, in a second instance of conducting the transforming, the transformed signal is the reference transformed signal, and wherein in the second instance of conducting the transforming, the candidate signal processing function has one or more candidate signal processing parameters and the reference signal processing function has one or more reference signal processing parameters different than the one or more candidate signal processing parameters, and wherein in the second instance of conducting the transforming, the processor determines that the reference transformed signal is better quality than the candidate transformed signal, and the processor responsively substitutes the one or more reference signal processing parameters for the one or more candidate signal processing parameters, so as to have a modified candidate signal processing function for a next instance of conducting the transforming.
