Abstract
A method and apparatus for improving the intelligibility of the spoken word in an acoustic space comprise generating an electrical signal indicative of a word or words, inputting the signal to a signal processor including a signal compressor, comparing the amplitude of the input signal with a threshold level and compressing any part of the signal in excess of the threshold, expanding both the compressed and uncompressed signal and outputting the expanded signal as an audible signal.
