Abstract
According to one embodiment of the present invention, a digital hearing device is disclosed. The digital hearing aid includes a microphone for receiving sound, which may include an analog signal. The analog signal is converted by a first converter into a digital signal. Filters are provided to divide the digital signal into multiple signal parts. A signal processor may be provided for each signal part, and performs signal processing on its respective signal part. An adder adds the output of the signal processors, which results in a processed digital signal. A second converter converts the processed digital signal back into an analog signal. A speaker then outputs the analog signal. According to another embodiment of the present invention, a method for enhancing sound is provided. The method includes the steps of: (1) receiving sound containing an analog signal; (2) converting the analog signal to a digital signal; (3) dividing the digital signal into signal parts; (4) performing signal processing on the signal parts; (5) adding the processed signal parts, resulting in a processed digital signal; (6) converting the processed digital signal to a processed analog signal; and (7) outpu…
