    • PROBLEM TO BE SOLVED: To provide a digital signal processing system for sound radiators generating masking sounds, a background music and a paging function.
      SOLUTION: The sound processing system to be used with a plurality of sound radiators is provided with a telephone interface accepting paging signal inputs, a microcontroller for accepting a plurality of user-selected sound radiator equalization and space equalization settings and receiving a paging control signal from the telephone interface, a digital signal processor for generating and filtering masking noise and processing the masking noise and the paging signal on the basis of the user-selected settings for distribution to the sound radiators, and an audio amplifier for modulating and amplifying the output signal from the digital signal processor to deliver the output signal to the sound radiators.
