 ultrasonic transducers, voice imitation, Turbo mode, 100% jamming!!!

  Device’s transducers emit special high frequency sound waves (pattern of the sound is determined by software in accordance with the specially developed algorithm) with the sound pressure reaching 120 dB at 1 m distance from the transducers. Effective range of jamming the eavesdropping devices at a distance of up to 7 meters.

Moreover, the speaker produces an acoustic speech-like signal with adjusted volume. 

      ​​​​​​​The frequency of the ultrasound regulated by the microcontroller and vary in accordance with a specially designed (for maximum efficiency of suppression) Copyright algorithm. The unique algorithm of audio interference cannot be cleared by any noise-clearance methods.  The ultrasonic signal affects the listening devices (recorders, microphones, cell phones, etc.), with the result that they record only illegible noise and absolutely impossible to distinguish any details of the conversation. Ultrasound inaudible to the human ear, so it is not interfere with conversation.

            The device is designed to protect conversations areas from eavesdropping. Device blocks wireless microphones, tape recorders, RF transmitters, hard-wired microphones and 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 in jamming the eavesdropping devices. 

      Effectively protects against eavesdropping and recorders. Protect confidential conversations, meetings, business conferences and secret meetings against eavesdropping.

       Main feature of this Device is unique Technology  - TURBO mode, which further improves the efficiency of suppression and ensures maximum privacy of conversation.
In Turbo mode activated a special generator that emits ultrasound of slightly different frequency than other emitters of the device.
The interaction of ultrasound signals having different frequencies leads to that the efficiency of suppression is greatly increased at the same power emission. This is unique development  applied in this device.

 The device should be placed so that the transducers be directed towards possible location of eavesdropping devices (tape recorders, microphone, "bugs" etc.), for example, toward the new visitors or clients. 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 conversation in a low voice but so that you hear well each other without repeating every word. Use TURBO mode for more effective jamming of the microphones.

 Do not switch on the acoustic speech-like signal when you want the device to be hidden. Note that this is somewhat reduces the effectiveness of the device (the manufacturer cannot guarantee that if you use only one ultrasonic signal the device will jam all tape recorders).

 It is recommended to connect the device to external speakers (e.g. computer) through the special jack in order to more effectively expose the acoustic speech-like signal in a large room. This will protect the large conversation area from eavesdropping as well as to prevent from eavesdropping by external directed microphones (such as laser).
