The Portable Masking Kit (PMK-2) protects private conversations by injecting voice masking noise into structural surfaces, gaps, and free space, making conversations unintelligible to anyone outside the room.  PMK-2 includes 2 sets of Voice Masking Generators (2) and transducers (4 with cables) to defeat acoustic leakage and eavesdropping devices like:

  • Wired wall devices

  • Contact microphones

  • Hidden audio transmitters

  • Laser/reflections from windows

  • ​

Efficiency: This kit provides a temporary audio security solution when you need to get in, set up voice masking security, and get out.

​

Usability: Create a Voice Masking perimeter to protect against structure bound audio threats.

​

Portability: The Portable Masking Kit, PMK-2 packs 2 Voice Masking Generator sets (unit, transducers, cables) in a hard shell case for easy transport with wireless charging in the case.
