The Advanced Digital Noise Generator

The Stealth noise generator is designed to prevent listening though devices that cannot be detected by conventional countermeasures and installed around the perimeter of a room – wired wall microphones, contact microphones, AC outlet transmitters and window systems based on the reflection of laser/infrared/microwave beams. It is an excellent addition to high level countermeasures. It uses a combination of transducers and speakers placed strategically throughout a target area to create a blanket of masking noise that covers private conversations from eavesdropping. 1 year warranty from defects.

Note** This is a specialty item, final sales item (non-refundable).

It is well-known that sound distributes though walls, doors, windows and other constructions. In some materials sound travels even better than through air. For example, water is a good conductor and a heating system can pass a conversation out of a room. Eavesdroppers take advantage of this with the use of contact microphones. These microphones pick up the vibrations from the air ducts, plumbing, structures, walls, windows, doors, floors, ceilings and more. The microphones may not be in the same room as the conversation, but may be several floors or rooms away attached to a pipe or other fixture.

 

TRULY RANDOM NOISE

The Stealth noise generator consists of 3 independent white noise digital generators. “White” means that the noise is fully random and is equally distributed along the voice spectrum. This distribution provides complete resistance against the filtering of a conversation. Another feature of white noise is its unpredictability i.e. there is no method to wipe it out from a recorded conversation.

 

VOICE MASKING

Men’s and women’s voices consist of lots of frequencies simultaneously produced during speech. These frequencies lie between 100 Hz and 6000 Hz. Listening devices usually have a narrower range mostly because of size limitations, the scheme of the device and battery time. The  Stealth noise generator has a range of 250-5000 Hz which is optimal to cover all types of voices and suppress all listening devices.

 

OPERATION

The  Stealth DNG-2300 uses a combination of transducers and speakers placed strategically throughout a target area to create a blanket of masking noise that covers private conversations from eavesdropping. Each transducer utilizes adapters for mounting to a variety of surfaces such as walls, windows, ductworks, plumbing, etc. The three separate channels allow the user to tailor the noise for separate materials, allowing greater flexibility and increased protection.

 

LOOPBACK INPUT

The  Stealth noise generator has an input LOOPBACK which allows easy and fast tuning to the necessary level of noise. Optional probe microphone E-DNG-MIC and probe stethoscope E-DNG-STET are used for the required measurements.
