Adaptation dynamic range optimization sound processor

摘要

(57) Abstract Being the sound processor, means (401) and the variable gain which analyze one sound signaling to many frequency band it includes the means (403) which are applied to each frequency band individually. Gain is applied under controlling the many gain relative means, (409) these gain relative means makes many statistical distribution evaluation value each, in regard to each signal, compares this evaluation value, with the specified value of the auditory response parameter which in memory (411) is retained. As for the many frequency band which can do gain amendment, the single sound signaling generates there to be recombined (415), with that. This device in the form of the dedicated hardware making implement and it may make implement in the form of the software which operates on the microprocessor.
