THINK TANK - Mark I and THINK TANK - Mark II

Abstract

The principal object of the present invention relates primarily to the provision of a Sound Proof Chamber ( 10 ). Secondly to an Electronic Surveillance Bug Proof Chamber. The latter being an enhancement of the former embodiment. Both embodiments having a sealed cavity within all surfaces of said chamber that form the plastic enclosure, and to subject said cavity to a Partial Vacuum of Specified Pressure. The type of installation required is indicative of its intended use. For high level applications, a combination of absorbing acoustic, and radio frequency blocking surfacing, and electronic sounds detector are used to restrict or detect the transmission of sounds within said enclosure. It has been proposed to manufacture the embodiment in assembly kit form to the consumer, in a variety of colors and incremental sizes.

1 . A sounds transmission restricting chamber enclosed completely or partially by a vacuumed cavity comprising: 
 a. an opening for allowing access having closing means, and    b. having an air exchange system for air revitalization within, and    c. having all frequency scanning means for eavesdropping detection alert,    whereby said chamber will restrict the transmission of sounds.
