ANG-2200 Acoustic Noise Generator

2 494  incl. TAX
1 995  excl. TAX

The ANG-2200 Acoustic Noise Generator creates a perimeter of noise that defeats acoustic leakage eavesdropping devices not to mention wired microphones inside walls, contact microphones, audio transmitters located in AC outlets, and laser/microwave reflections from windows.

  • Offers two channels, each with high and low frequency control to compensate for material composition, with truly random noise sources
  • Masking system injects noise into the environment perimeter and not directly into the environment—allowing normal conversation while defeating eavesdropping devices
  • Optional accessories (transducer, omnidirectional speaker, window mounts) can be purchased to tailor the ANG-2200 to the environment of concern

Principle of operation

The ANG-2200 injects tuned masking noise into perimeter structures to mask structure-bound audio. Acoustic Spectrum Analysis Software (ASA-2000) ensures the masking noise is properly adjusted to provide adequate masking without being too loud or disruptive. Independently controlled dual channels for use on different structures “Tunable” masking noise for specific environmental requirements. ANG-2200 provides an eavesdropping defense against devices that may not be detected by conventional methods System configuration should be tailored to the environment.
