Abstract:
A hearing compensation system comprising:an input transducer for converting acoustical information at an input thereof to electrical signals at an output thereof;a differential analog-to-digital converter sampling said electrical signals output from said input transducer at an input thereof and outputting differential signal samples at an output thereof as digital signals, said differential signal samples representing the difference between successive samples of said electrical signals;a digital signal processing circuit having an input connected to said output of said differential analog-to-digital converter and operating on said differential signal samples to form processed differential signal samples at an output thereof;an integrator having an input connected to said output of said digital signal processing circuit to form a sum of successive ones from said processed differential signal samples at an output thereof;a digital-to-analog converter having an input connected to said output of said integrator to form an analog signal from said sum of said successive ones of said processed differential signal samples at an output thereof; andan output transducer having an input connected to said output of said digital-to-analog converter to convert said analog signal from said digital-to-analog converter to acoustical information at an output thereof.
