DNG 2300 3-Channel White Noise Generator for Anti-Eavesdropping

Keep conversations inside the room where they belong. The DNG 2300 creates a controlled white noise barrier that stops sound from leaking through walls, windows, and structural gaps.

Instead of worrying about hidden microphones or external listening methods, you get consistent acoustic protection that keeps sensitive discussions private.

Block sound leaks and secure every conversation

✅ Stop conversations from being captured through walls, glass, and ventilation paths

✅ Disrupt laser and microwave listening attempts targeting window vibrations

✅ Mask vibrations that contact microphones rely on to capture audio

✅ Cover both solid and light structures for full-room protection

✅ Maintain control with separate channels for transducers and speakers

✅ Expand coverage with support for up to 12 speakers and multiple transducers

The system works by generating non-filterable white noise across the frequency range of human speech. This noise is distributed through connected transducers and speakers, forming a "sound curtain" that blocks usable audio from escaping the space.

Transducers attach directly to surfaces like concrete, glass, drywall, or pipes, turning those structures into active barriers against vibration-based listening. At the same time, speakers fill the air with masking noise, adding another layer of protection.

With three independent channels, the DNG 2300 gives you flexible control over how the noise is distributed. Each transducer channel supports up to 12 units on solid structures or up to 24 on lighter materials, while the acoustic channel supports up to 12 speakers. A mute control lets you temporarily silence speakers without shutting down the system.

Create a barrier that keeps conversations contained.

This approach avoids the limitations of traditional detection tools. Instead of trying to find hidden devices, it blocks all vibroacoustic leakage at the source, making captured signals unusable.

Adjust channels to match your space and protection needs.

Secure your space by stopping sound from leaving it.
