The present invention relates primarily to the provision of a Sound Proof Chamber (10), and optionally also relates to an Electronic Surveillance Bug Proof Chamber. Both embodiments comprise a sealed cavity located within all walls, roof, and optionally the floor surfaces of said chamber, which cavity is kept under a Partial Vacuum. The type of chamber which is fabricated is dependent on its intended use. For example, in high level applications, an additional combination of absorbing acoustic, and radio frequency blocking surfacing, and electronic sounds detector can be used to further restrict or detect the transmission of sounds within said enclosure. In lower level applications, the vacuum cavity may have sufficient noise suppression capability. The chamber is of the present invention is preferably manufactured using modular components in an assembly kit form in order to provide the consumer with a variety of chamber shapes, colors and incremental sizes.
