Abstract:
A digital hearing device, comprising:at least one microphone for receiving sound, the sound including an analog signal; a first converter for converting the received analog signal to a digital signal; a plurality of filters for dividing the digital signal into a plurality of signal parts where each filter of said plurality of filters is assigned a desired range of frequencies; a plurality of speech detectors with a separate speech detector coupled to each filter of said plurality of filters for detecting the presence of speech in the each of the signal parts, a signal processor provided for performing signal processing on each signal part comprising a separate programmable compression filter for each of said signal parts coupled to each corresponding filter of said plurality of filters and each speech detector for each of said signal parts and wherein said speech detector for each of said signal parts actively detect the presence of speech and change coefficient settings on said compression filter for each signal part; an adder for adding the output of the signal processor, resulting in a processed digital signal; a second converter for converting the processed digital signal to a processed analog signal; and a speaker for outputting the processed analog signal.
