Portable Masking Kit (PMK-8)
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
- Hidden audio transmitters
- Laser/reflections from windows
