Selective Acoustic Soundproofing Device

A selective acoustic soundproofing device comprising:

• a housing defining an internal space, said housing having a first end and a second end, said first end and said second end being configured for coupling to an exhaust system of a vehicle such that said internal space is in fluidic communication with the exhaust system, said housing being ovally shaped when viewed longitudinally;
• a wall coupled to said housing and positioned in said internal space, said wall extending from proximate to said first end to proximate to said second end of said housing defining a first passage and a second passage between said first end and said second end, said wall being coupled to and extending between a top and a bottom of said housing;
• a plurality of first pipes, each said first pipe being coupled to and extending through said first end of said housing such that said first pipes are in fluidic communication with said internal space, said first pipes being configured for coupling in-line to the exhaust system of the vehicle, said plurality of first pipes comprising one said first pipe, said first pipes being circularly shaped when viewed longitudinally;
• a plurality of second pipes, each said second pipe being coupled to and extending through said second end of said housing such that said second pipes are in fluidic communication with said internal space, said second pipes being configured for coupling in-line to the exhaust system of the vehicle, said plurality of second pipes comprising one said second pipe, said second pipes being circularly shaped when viewed longitudinally;
• a selector coupled to said housing proximate to said first end of said housing, said selector being configured for selectively directing sound pressure from an engine of the vehicle through said first passage and said second passage, said selector comprising:
• a first plate hingedly coupled to an endpoint of said wall such that a terminus of said first plate extends into said first pipe, said terminus being arcuate such that said first plate is positioned for pivoting for positioning said terminus adjacent to an inner surface of said first pipe,
• an actuator coupled to said housing, said actuator being operationally coupled to said first plate, wherein said actuator is positioned on said housing such that said actuator is positioned for selectively pivoting said first plate for directing the sound pressure from the engine through said first passage and said second passage, said actuator comprising a servomotor, and
• a switch configured for coupling to a surface of the vehicle proximate to a driver of the vehicle, said switch being operationally coupled to said actuator, wherein said switch is positioned proximate to the driver such that said switch is configured for the driver to selectively direct said actuator for pivoting said first plate for directing the sound pressure from the engine through said first passage and said second passage;
• a baffle positioned in said first passage, wherein said baffle is positioned in said first passage such that said baffle is configured for acoustic quieting of loudness of the sound pressure generated by the engine of the vehicle when said selector is positioned for directing the sound pressure from the engine through said first passage relative to when said selector is positioned for directing the sound pressure from the engine through said second passage, said baffle comprising a plurality of inserts coupled to said housing and positioned in said first passage defining a plurality of resonating chambers, wherein said inserts are positioned in said first passage such that said resonating chambers are harmonically tuned for causing destructive interference of the sound pressure, said plurality of inserts comprising:
• a plurality of second plates, each said second plate being coupled to and extending from said wall into said first passage, each said second plate extending transversely from said wall toward said second end of said housing, said plurality of second plates comprising three said second plates, and
• a plurality of third plates, each said third plate being coupled to and extending from said housing into said first passage, each said third plate extending transversely from said housing toward said second end of said housing such that said second plates and said third plates are alternately positioned within said first passage, said plurality of third plates comprising two said third plates;
• a pair of fourth plates, each said fourth plate being coupled to and extending transversely from said housing into said internal space proximate to said first end, each said fourth plate being coupled to said first end adjacent to said first pipe;
• a pair of fifth plates, each said fifth plate being coupled to and extending transversely from said housing into said internal space proximate to said second end, each said fifth plate being coupled to said second end adjacent to said second pipe;
• and
• wherein said switch is positioned proximate to the driver such that said switch is configured for the driver to selectively direct said actuator for pivoting said first plate for directing the sound pressure from the engine through said first passage and said second passage, wherein said second plates and said third plates are positioned in said first passage such that said resonating chambers are harmonically tuned for causing destructive interference of the sound pressure for the acoustic quieting of the loudness of the sound pressure generated by the engine of the vehicle when said first plate is positioned for directing the sound pressure from the engine through said first passage relative to when said first plate is positioned for directing the sound pressure from the engine through said second passage.
