Tritech Mumbler offer for total privacy in any environment. This "white noise" generator is a sophisticated electronic broadcaster, about the size of a paper-back book. It is emits random noise at a level which is barely audible to human ears but will confound listening devices with 90% reliability. Anything within a 3-meter radius of the Mumbler will be "camouflaged" by white noise, thereby allowing private conversation and defeating eavesdropping.[1]
