BugHunter DAudio bda-2 Voices

The "BugHunter DAudio bda-2 Voices" microphone, listening device and voice recorder suppressor with 5 ultrasonic emitters and an acoustic silencer has not only ultrasonic emitters, but also a powerful speaker that generates acoustic interference. Thanks to the complex effect of ultrasound and speech-like sound, it silences devices with microphones: voice recorders, radio microphones, mobile phones, wired, wireless and directional microphones.

The advanced model, unlike the prototype "BugHunter DAudio bda-1", has not only ultrasonic emitters, but also a powerful speaker that generates acoustic interference. Thanks to the complex effect of ultrasound and speech-like sound, it silences devices with microphones: professional voice recorders (E-dic Mini, Gnome, Magpie, etc.), radio microphones, mobile phones, wired, wireless and directional microphones. Very effective and reliable suppressor.

It does not interfere with the conversation at all: if necessary, the volume of the acoustic interference can be reduced or turned off altogether, then the suppressor will work absolutely silently (since ultrasound is inaudible to humans).

THE PRINCIPLE OF OPERATION OF THE SUPPRESSOR:

The device generates an ultrasonic signal using 5 built-in emitters. The ultrasound frequency is set by the microcontroller and changes according to a specially developed algorithm. The ultrasonic signal generated by the device affects the recording tracts of listening devices (voice recorders, cell phone microphones, etc.), as a result of which they record only indistinct noise, from which it is absolutely impossible to distinguish any details of the conversation ...

In addition, the powerful speaker creates a speech-like sound interference, which also destroys the meaning of the conversation: because of it, spy devices only record unintelligible mumbling, it becomes physically impossible to restore the conversation. Sound interference is generated haphazardly, so it can not be filtered out even on special equipment.

This comprehensive protection guarantees the highest possible reliability and confidentiality. Spy devices with microphones become useless "toys", as they simply can not remove the necessary information. They only record unintelligible noise, from which individual words and phrases cannot be distinguished. At the same time, the generated interference does not interfere with negotiations, since ultrasonic signals are not audible to the human ear, and the volume of the speech-like signal is easily adjusted (if desired, it can even be output to external speakers via a special connector). You and your interlocutor will hear each other.

NOTE:

The only inconvenience when using TURBO mode is that when the frequencies are superimposed, their spectrum goes into the audible range, so the device will start to make a little noise. That is, even if you do not use acoustic interference, but you have turned on TURBO mode, you will not be able to use the suppressor completely secretly. However, this does not prevent you from talking at all, you do not have to strain your voice to speak louder.

It should be understood that without the use of acoustic interference, the reliability of protection against espionage decreases. If 100% privacy is really important to you and you need to suppress absolutely ALL devices with microphones, you will have to suffer a little inconvenience due to the noise of the blocker. But you will know for sure that no one will be able to eavesdrop on your conversation.

THE USE OF A SUPPRESSOR

Anyone can use the suppressor, even a layman. Everything is very simple, no complicated settings are required. You just need to direct the suppressor emitters in the direction where it is assumed that there are wiretapping devices, and turn it on by turning the mechanical handle (located on the front side).
