Our portable white noise generator kit has 4 separate units. Each unit can be used as a stand alone noise generator to cover approximately 150 square feet. These four units come in a portable case and can be utilized for conference rooms and off campus office meetings. Easy to set up you can add a device to each point of the compass and keep your conversations private.
The white noise is audible not only to your ears but to any recording device that uses a microphone. The background noise created will mask your conversations so the only person who hears what you have to say is the person you are speaking to.
