Microphone Suppressor (Ultrasound + White Noise) Anti Eavesdropping Generator BugHunter BDA-3
Description
Microphone, bug and tape recorder suppressor "BugHunter DAudio bda-3 Voices" with five UV-transducers on the side and two UV-transducers on the top and an acoustic silencer. - Ultrasonic exposure+voice imitation = 100% jamming. - Absolutely soundless operation possible. - Jamming range up to max - 7 m (23 ft), super effective - 2 m (7 ft). - Very powerful emission - up to 120 dB. - Ability to plug external ultrasonic speaker for better effect. The device is designed to protect conversation areas from eavesdropping. Device blocks wireless microphones, tape recorders, wired microphones and most of professional digital tape recorders including tape recorders installed in mobile phones (smart phones). Ultrasonic inaudible noise signal as well as acoustic speech-like noise signal** are used in jamming the eavesdropping devices. **The manufacturer cannot guarantee that if you use only one ultrasonic signal (or insufficient level of acoustic speech-like signal volume) all tape recorders and recording devices will be jammed. Note: ultrasound has certain physical limitations due to being reflected from hard surfaces and absorbed by soft materials.
