Microphone jammer "BugHunter DAudio bda-3 Voices" features 7 ultrasonic transducers and an acoustic interference thus it’s capable of jamming all types of eavesdropping devices. Special "TURBO" mode provides maximal efficiency of ultrasonic interference even in the most complicated cases. Also, there’s an option to connect an additional external ultrasonic speaker as well as acoustic speakers. The device is powered by a built-in battery and by 110/220V mains.

The device suppresses all microphones by ultrasound combined with a speech-like noise Joint use of ultrasonic and acoustic (speech-like) interference provides protection against all known bugs. Speech-like interference turns record of your conversation into indistinct set of sounds. Restoring the conversation becomes physically impossible even by professional devices, including digital and laser microphones, to say nothing of smartphones and wired microphones. |

|
Effective against newest noise-cancelling and waterproof smartphones The device features upgraded system of ultrasonic suppression which provides even more effective jamming of eavesdropping devices and newest smartphones. There’s an option to connect one or several additional ultrasonic speakers (not supplied with the device). Additional ultrasonic speakers can create more powerful ultrasonic interference or suppress microphones located out of range of main transducers. |

The volume of the speech-like interference can be easily adjusted down to full deactivation. If the speech-like noise if turned off, the device operates silently. However, jamming of all possible eavesdropping devices is not guaranteed with the speech-like noise turned off. |
The device generates very powerful ultrasonic signal (at least 120 dB) which suppresses microphones at a distance of up to 7 m (23 ft). Effective range reduces to 2 m (6 ft) if used against newest iPhones with improved noise-cancelling system. |
In addition to 5 standard transducers, there are 2 additional transducers located on the top panel of the device. Emitting interference in a vertical direction these 2 transducers create a "virtual wall" that protects you against any microphones or dictaphones located behind it. |
