DISCLAIMER: Please note that BDA-3 is just a tool, complementing and reinforcing the measures taken to protect you from eavesdropping and recording. To increase the security of your conversation do not increase the volume of your voice. A volume similar to what you would use in a crowded coffee shop is ideal. If possible, lean forward towards your interlocutor or sit closer to each other, then place the device on the table between you. Create as many sources of ultrasonic emission as possible. Always consider using audible white noise interference.Do not hide the device in a pocket or bag while in use. The unit should be as close to the speakers as possible so that the conversation is drowned in noise.

External ultrasonic speaker is sold seperatleyFAQ
How effective is BDA against new phones/ iPhones/ old analog dictaphones?
-In silent ultrasound mode you need at least 2 (or better 3) ultrasonic sources for jamming recording by waterproof phones. For example, BDA-3 + two external speakers. But 100% result is only possible with using of white noise function.
-Ultrasound jamming works poor with Analogue Dictaphones, and usage of white noise is necessary.
How effective is BDA in ultrasound (silent) mode?
-The highest effectiveness is reached with digital recorders when it's placed on the same level with recording device between the source of sound and the recording device (it plays the role of a virtual wall).

Can I use the BDA so nobody knows it?
-In ultrasound mode it is almost inaudible by most people. Additional external speakers should be placed under the table.


How long does BDA work without charging, can it be used while charging?
It depends on intensity of use; maximum is – up to 3 hours. Device can be used while charging.
What is effective distance of jamming?
-When placed on the same level with recording device – up to 7 m. For waterproof phones – 2 m.
Can it jam phone signal or video recording?
-No, it only affects the membrane of microphones.
What types of microphones can BDA suppress?
-When using both ultrasound and white noise BDA suppresses recording on all types of microphones including Laser microphones that reads vibrations on the glass. Such combined interference is extremely difficult to clean.
Operating principle
Device generates ultrasonic signal through 7 transducers. Frequency is determined by a micro-controller and variates according to a specially developed algorithm. Ultrasonic signal affects recording paths of spyware which results in them fixating only indiscriminate noise in which conversation can't be distinguished.
Besides, powerful speaker creates acoustic speech-like interference which destroys the meaning of the conversation: because of it spyware fixates only indiscriminate muttering, restoring the conversation becomes physically impossible. Acoustic interference is generated randomly so it can't be filtered out even on special equipment.Flexible volume adjustment
Acoustic speech-like interference guarantees the confidentiality of the conversation but has one flaw – unlike ultrasound it can be heard and my be a nuisance in a conversation. Our developers took this into account and developed "BugHunter DAudio bda-3 Voices" with an ability to adjust the volume of the acoustic interference. You can always adjust the volume so that device won't muffle your speech and you could speak comfortably. If suppressor is a nuisance, just turn the volume down. Turning the knob to a minimum you will turn the acoustic interference off.
If acoustic interference is turned off, suppressor will be working completely silently (except TURBO mode). One will not pay attention to the working device. If you hide it under the table, for example, there will be no clear evidence that suppresor is working.
But without the acoustic interference reliability of protection becomes lower. If you want to be 100% certain that ALL devices with microphones are suppressed, you will have to tolerate small inconvenience.
Use the suppresor stationarily or portably.
"BugHunter DAudio bda-3 Voices" can be powered by power supply or by a built-in battery. Its charge will last for a few hours which is a good number for a device of this power. Wherever you go, suppresor will always be with you ready to protect you from spying. And you can charge it and use stationarily when you get access to a power supply.
