Description Creating audio noise in the voids/cavities increases the general level of protection by preventing such kinds of listening as: Listening with the help of a wall stethoscope placed behind the construction adjacent to cavity (typically from a top floor behind the drop ceiling) Leakage of sound outside the target room through the void/cavities (for example, through the ventilation or common holes for the pipes of heating system) Bringing a wired microphone to a void or cavity Hiding a covert surveillance device in a void or cavity 1 x SP2300 speaker per every 100 feet The SP2300 speaker, when connected to a iProtect white noise generator, will create efficient interference to all of the mentioned kinds of eavesdropping. The DNG-2300 is the recommended white noise generator for the SP2300. Since the SP2300 is assembled from 3 speakers, each of them can be used separately for smaller voids. The output has adjustable volume and can feed up to 12 speakers simultaneously.
