Protect Private Conversations

The Portable Masking Kit (PMK-8) protects private conversations by injecting voice masking noise into structural surfaces, gaps, and free space, making conversations unintelligible to anyone outside the room.  Portable Masking Kit creates a perimeter of masking noise that defeats acoustic leakage and eavesdropping devices like:

  • Wired wall devices
  • Contact microphones
