Add PC Management Software:


The Professional Acoustic Noise Generator is designed to keep your meeting rooms secure using a perimeter of noise around you that defeats wired microphones and audio bugs.


With the Professional Acoustic Noise Generator, you can secure your most confidential meetings from wired microphones and other recording equipment, as well as the tiny RF audio bugs hidden inside walls, contact microphones, audio transmitters located in AC outlets, and laser/microwave reflections from windows. 

And you can hook up to 36 speakers in any combination. Note, the base unit does not make any noise, you will need to add the speakers, and there is a link below.

When using 12 speakers, you have full power, 1/2 power with 24 speakers, and 1/3 power with 36. You can also purchase optional software for your pc that will let you adjust the sensitivity.

Now you can add the PC management software to your order that will help to find the ideal noise level for your room. The Acoustic Noise Generator will make loud, white, random noise. The idea is to find a base level for the room, then you can adjust the noise level so you can still talk, yet protect your conversation from prying ears.


The Professional Acoustic Noise Generator generates true random noise:

The ANG-2200 contains two separate random noise generators. There are several products in a host of markets that use noise generators, but most of these use pseudo-random noise. Pseudo- random noise is generated by a mathematical formula or a precalculated list of values and is in most cases predictable. This predictability allows a sophisticated eavesdropper to correlate on this predicted noise and extract the room’s information. True random noise is naturally generated and completely unpredictable and eliminates this threat. The ANG-2200 uses true random noise.

Professional Acoustic Noise Generator Benefits:

  • Keep your most imnportant information private and away from ears.
  • Prevent cell phones, audio bugs, and digital audio recorders from recording conversations.


Most sound masking systems like the white noise audio jammer, which injects static noise into an otherwise quiet environment, causing any speaker  to raise their voices above the noise level to communicate, which invariably, eliminates the benefit of noise masking.

Not so with the Professional Acoustic Noise Generator, which has a masking system that injects noise into the environment perimeter, and not directly into the conversation. This approach allows normal conversation while defeating eavesdropping devices that rely on acoustic leakage.

The ANG-2200 offers two channels each with a truely random noise source. Both channels have a seperate high and low frequency control in order to compensate for loses found in the enviroments material composition.

The REI noise masking system consist of a main unit (the ANG-2200) and three optional accessories that are purchased to tailor the system to the environment of concern. The ANG-2200 accessories are:

  • TRN-2000 Transducer used to inject acoustic noise into walls, ceilings, windows, plumbing, and air ducts.
  • OMS-2000 Omnidirectional Speaker used to project acoustic noise into drop ceiling air spaces, closets, crawl spaces, and air ducts
