The device is designed to protect conversations & areas of conversation from eavesdropping devices including: wireless microphones, tape recorders, hard-wired microphones & most of professional digital tape recorders including tape recorders installed in mobile phones (smartphones), Ultrasonic inaudible noise signal as well as acoustic speech-like noise signal are used to muffle the eavesdropping devices.
The device should be placed so that the transducers are directed towards the possible locations of the eavesdropping devices if possible? these types of device could be tape recorders, microphone, "spy bugs" etc.
Or for an example, point the device towards a suspicious visitors or clients, basically make sure the device is facing outwards from your speech. The optimal distance from the transducers to microphone of the eavesdropping device is up to 2 meters.
Then switch ON the device and adjust the volume of the acoustic speech-like signal so that you can still hear the person you are talking to. You should hold your conversation at a slightly low voice then usual but so that you hear each other without having to repeat every thing. if you feel there is a situation that needs a full response you should use TURBO mode for more effective jamming of any hidden microphone or smart phone microphones.
The device can be connected to external speakers (e.g. computer) through the special jack in order to effectively expose the acoustic speech-like signal in a large room. This will protect a large conversation area from eavesdropping as well as prevent eavesdropping by external directed microphones (such as laser).
