Abstract
A vibration masking noise system for delivering masking noise into a room or building is designed to vibrate part of the building structure so that masking noise is extended into the room. The system includes a noise generator, a spectrum shaper for shaping the noise, an amplifier for amplifying the shaped noise and a transducer mechanically connected to the structure for converting the masking noise into vibrations of the structure.
