1. A sound limiting device that is adapted to secure to a mechanical device having a mechanical device outer surface, a mechanical device operational end and a mechanical device external component connection end, the sound limiting device comprising:
an acoustic chamber that includes an acoustic hood that is configured to fit around the mechanical device operational end and a retaining collar that is configured to seal around the mechanical device outer surface, the retaining collar further adapted to allow external access to the mechanical device operational end;
the acoustic chamber further including a neck sleeve, the neck sleeve configured to couple with the acoustic hood on one end and to an end cap on the other end to seal the mechanical device from an external atmosphere; and
a vacuum pump connected to the end cap, the vacuum pump configured to extract exhaust air and vibrational energy out from the acoustic chamber.
