Privacy-7 audio curtain

The Privacy-7 audio curtain was a type of privacy field developed to muffle sound emitted from a room.

Description
The Privacy-7 was comprised of two matched rods lined with microemitters that create a sound-dampening field between them. The device could be used in conjunction with several sets of rods that could fully enclose speakers. Typically placed on horizontal surfaces around a speaker, the device could also be placed at physical gaps, such as a doorway.
