The iProtect DNG-2300-4 White Noise Generator is a professional-grade sound masking system designed to protect private conversations from eavesdropping, laser microphones, and audio leakage through walls, ceilings, and vents.
When paired with the included transducers and acoustic speakers, the generator produces low-level, full-spectrum interference that neutralizes listening devices. It creates subtle vibrations across structural surfaces, ensuring that any bugging device records only white noise instead of actual speech.
Perfect for corporate offices, government facilities, conference rooms, and high-security sites, the DNG2300-4 provides an effective and scalable acoustic protection solution.
