Product Description

Being used together with the device it lets organize a more effective system which protects your conversations from recording by directing sources of ultrasound from different directions.

Device is powered from 110/220V power source via an adaptor (included).

Super-effective ultrasonic suppresion system "BugHunter BDA-3 " with additional ultrasonic speakers

​​​​​​​​​​​​​​If you already have a microphone suppresor "BugHunter DAudio bda-3 Voices" or you plan on getting one, we recommend to add one or two ultrasonic speakers to it. By paying a little extra, you will be able to protect your meeting room from spyware more reliably. By itself the suppresor offers protection directly in front of you and additional speakers generate interference from other sides. In this case ultrasonic interference becomes denser and more effective at suppresing spyware.

Using additional ultrasonic speakers is more economical in cost than using two or three "BugHunter DAudio bda-3 Voices" suppresors and a lot more efficient than buying expensive suppresors with a large number of transducers pointed in one direction. You need to consider that with every meter distance, power of ultrasonic interference decreases by 2-3 times, that’s why bulky analogues with “50 unidirectional transducers” won’t create the result you expect. All these are not allegations but facts verified by experiments.

On the front side of the speaker 4 ultrasonic transducers are placed and audio connector and a power adapter jack are located on the back.

How to correctly place ultrasonic speakers.

Depending on the size of your room and location of people you are talking to, you might require one or two additional ultrasonic speakers. We suggest only some of the possible layouts on the base of which you can determine what places work best in your case.


If you have only one speaker place it under the table. Or point the side with transducers towards the other person while the suppresor itself will be lying on the table in front of you. When using two speakers, usually one speaker is placed under the table and other one is placed on the wall or shelf.

Operating principle

Device generates ultrasonic signal through 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.
