A system to suppress sound emerging from speakers and the generation of same at a distance is presented. This system includes devices to handle audio which when manipulated, in their different applications, are capable of reducing or of eliminating the acoustic impact or sound unwanted by people or by the environment. The present system includes a combination of known devices to handle audible signals or sound that allow for the analysis of the characteristics or specifications of sound or for the generation of an identical signal which can be inverted and mixed with the output signal to cancel sound and at the same time to suppress the inverted signal at a distance and in this way to once again generate sound at a distance. Considering the above, the scope of the present invention falls within the scope of the universe to transmit, mix, and suppress sound. |

1. A system for sound suppression and controlled generation of sound at a distance, said system comprising:
a transmitting source generating an electric signal; an electronic transducer being in communication with said transmitting source and converting said electric signal into a base signal; a conditioner being in communication with said electronic transducer and producing an output signal based on said base signal; an electronic device being in communication with said electronic transducer and performing a metrical spectrum analysis of said base signal so as to determine a counterphase signal, said counterphase signal being compatible and equalized to said base signal; a parallel high speed distributed processor in communication with said electronic device so as to receive said base signal and said counterphase signal; a plurality of digital memory modules, each module containing databases of characteristics of different instruments and arrangements, said memory modules being in communication with said parallel high speed distributed processor, wherein said parallel high speed distributed processor compares said base signal to said characteristics; a counterphase wave generator being in communication with said parallel high speed distributed processor and said electronic device so as to produce an output counter signal based on said counterphase signal determined by said electronic device; an equalizer being in communication with said conditioner and said counterphase wave generator, said equalizer receiving said output signal from said conditioner and said output counter signal from said counterphase wave generator and producing an acoustic signal comprised of said output signal and said output counter signal; a carrier transducer being in communication with said counterphase wave generator and producing a carrier signal related to said output counter signal; and an antenna placed at a distance from said transmitting source and being in communication with said carrier transducer so as to broadcast a wireless carrier signal, said wireless carrier signal interacting with said acoustic signal so as to control audibility of said output signal within said acoustic signal, wherein said base signal has analogical properties, digital properties, responsiveness, and resolution, wherein said electronic device determines said counterphase signal by identifying frequencies and overtones of said base signal, and performing corresponding qualitative and quantitative correlation, wherein said output signal and said output counter signal are integrated in said acoustic signal by said equalizer, said output signal and said output counter signal being compatible, said acoustic signal being transmitted to a speaker for broadcasting said acoustic signal, wherein said databases of said characteristics of different instruments and arrangements are comprised of base frequencies, tones and sub-tones of said different instruments and arrangements, wherein said parallel high speed distributed processor recognizes acoustic patterns and parameters of said base signal, said parameters being comprised of constitution, projection in real time, tendency, in real time, to anticipate reception, said counterphase signal being determined in real time, wherein said parallel high speed distributed processor performing selective and controlled analysis of said base signal from said electronic device, said base signal being simultaneously transmitted to said conditioner and said electronic device, and wherein said wireless carrier signal controls audibility of said output signal within said acoustic signal by at least one of a group consisting of a dispatcher and an electronic trigger, wherein perceived sound coming from said speaker depends on distance from said transmitting source. |
