Inside the Design

Keep voices and discussions from traveling from room to room with this sound masking and eavesdropping protection system. Ideal for CIA, FBI, law enforcement, correctional facilities, medical offices, law firms, courthouses and more. Metal ductwork creates a highly reverberant path that can easily carry conversations from one room to another or can be used to hide listening devices. The Dynasound DS2400 duct masker fills the interior of the air duct with protective sound masking. It can be used on walls or attached to the exterior of any pipe or duct, whether square or round, without any penetration into the duct itself. The Atlas M1000 sound masking speaker is designed to accurately reproduce the required spectrum of masking signal into the plenum space.

Sound System Features:

• Increases security by preventing eavesdropping on confidential conversations
• Protects against sophisticated electronic signal recovery techniques
• M1000 speaker is suitable for use above suspended ceiling systems in air handling plenum spaces
• DS2400 fills pipes, square ducts and round ducts, and walls with sound masking
• AM1200 self-contained sound masking system generates pink or white noise
• Easy-to-install 70V plenum rated speech privacy system
  
  

About the System Components

Atlas Sound M1000 Sound Masking Speaker

The Atlas Sound M1000 8" sound masking speaker assembly is designed to accurately reproduce the required spectrum of masking signal into the plenum space. With a majority of America’s workplaces having adopted an open office plan, favoring a labyrinth of cubicles over traditional closed offices, conversational privacy has become an increasingly sensitive issue. A properly designed sound masking system can significantly increase speech privacy and improve the overall work environment.

Atlas Sound AM1200 Self Contained Sound Masking System

The Atlas Sound AM1200 low profile sound masking system features a compact enclosure utilizing two efficient wide range 2" x 4" speakers that are powered by an internal 12W amplifier. Its selectable white and pink analog sources are incorporated to allow maximum masking design flexibility for office areas, common waiting areas, and professional offices where confidential conversations occur.

Dynasound DS2400 Pipe and Duct Sound Masker

The Dynasound DS2400 pipe, duct, and wall sound masker is used to protect pipes, ducts, and walls against human and electronic eavesdropping by filling them with full bandwidth sound masking. The unit may be attached to the exterior of any pipe or duct, whether square or round. It may also be attached to the vertical surface of any partition wall. The DS2400 is critical to the securing of pipes and ducts when DIAM and DCID requirements for SCIF need to be met. The DS2400 Soundmasker may be used to ensure eavesdropping protection of pipes and ducts that breach the perimeter of a secure environment by resonating these penetrations, filling them with sound masking and/or misinformation.
