Microphone, listening device and voice recorder suppressor "BugHunter DAudio BDA-1"

New product! It has no analogues in terms of ultrasonic power! Unique stationary microphone, listening device and voice recorder suppressor "BugHunter DAudio BDA-1" is equipped with 2 ultrasonic transducers. It generates a record-high ultrasonic interference power up to 135 dB! The interference is so powerful and dense that it passes through fabrics like steel needles, and effectively affects protected microphones (with protection class IP65-68) and voice recorders with AI filters. The device is completely stationary, powered by a 12V power supply (or battery). It is equipped with 2 remote controls with a control distance up to 98 ft (30 m).

High-power microphone suppressor "BugHunter DAudio bda-1"

Advantages:

• Record-high power and density of ultrasonic emission. Two large-format transducers operate at maximum frequencies without degradation and generate an ultrasonic field of unique power up to 135 dB. The generated interference penetrates even through fabric, so it is most effective against modern digital voice recorders and microphones with a degree of protection built into mobile phones and with AI filters.
• Unique suppression algorithm. Two modes work in combination: ultra-high frequencies (20-30 kHz) and powerful variable pulses. The interference literally "puts pressure" on the data acquisition devices, and sudden bursts do not allow the equipment to adapt and get out of the overload state. Recording becomes physically impossible.
• Compact and unobtrusive. The suppressor is small in size (4 x 4,7 x 2,1 in (100 x 120 x 55 mm)) and has a laconic design with acoustic fabric, so it looks organically on the table without attracting unnecessary attention.
• Ready to work "out of the box". The device is powered by a network, equipped with two remote controls for comfortable switching on/off, remembers the state when the power is turned off and restores it automatically. The device is stationary (powered by a 12V power supply), but it is also possible to connect a 12V battery and use the suppressor where there is no access to the electricity.

How does it work?

The professional new generation microphone and voice recorder suppressor "BugHunter DAudio BDA-1" is designed specifically to protect the meeting place from voice recording devices. Blocks ANY radio microphones, wired microphones, and most professional digital voice recorders, including voice recorders in mobile phones (smartphones) within a radius of 1,6 to 23 ft (0,5-7 m) (depending on the protection degree of the voice recorder).
The device generates an ultrasonic signal using 2 high-power built-in transducers with ultrasonic frequencies of 20-30 kHz. The ultrasound frequency is set by the microcontroller and changes according to the specially developed copyright algorithm (for maximum suppression efficiency).

"BugHunter DAudio BDA-1" suppressor affects protected microphones and voice recorders with AI interference filters

The combined ultrasonic signal generated by the device affects the recording microphones of listening devices (voice recorders, cell phone microphones, etc.). As a result, they overload over a large frequency range, begin to record extraneous noise randomly, or stop recording completely. For a voice recorder, the signal is perceived as a powerful gusty wind pressing on the membrane and interfering with the information perception. No noise reduction algorithm can separate such interference from the desired signal. The speech on the recording loses its intelligibility and cannot be restored.

Unique suppression system: ultra-high frequencies + variable interference

"BugHunter DAudio BDA-1" has received a new super powerful suppression system:

• Ultra-high frequency ultrasonic mode. Interference with power of up to 135 dB is formed in the range from 20 to 30 kHz, suppression is realized by powerful bursts of such signal. Ultra-dense and powerful broadband interference is formed in the air, which makes legible audio recording impossible.
• Powerful ultrasound with variable interference. Sharp flashes alternate with constant pressure, preventing the equipment from continuing normal recording. The interferences are generated randomly, which prevents devices with adaptive filtering algorithms from adjusting. Even the most "smart" voice recorders cannot cope with the task, as a result, the recording is unreadable and cannot be deciphered.

How to achieve maximum efficiency?

• If possible, choose a square room with a ceiling height less than 11,4 ft (3,5 m) for negotiations, since ultrasonic interference is reflected in such rooms, creating additional suppression power.
• Point the front panel at the intended recording source: the visitors' side, the meeting table, the entrance area.
• In rooms with reflective surfaces, the effect is enhanced by repeated reflections of ultrasound. In large rooms, it is advisable to use several appliances for uniform coverage.
• For complex scenarios (for example, aggressive AI filters or attempts to capture speech via vibro or radar methods through barrier structures), turning some of the transducers towards the walls helps: this increases the level of acoustic vibrations in the surfaces and complicates speech recovery further.

In large rooms, it is advisable to use several devices for uniform coverage, and combine different suppressors (for example, "BugHunter DAudio BDA-1" and "BugHunter DAudio BDA-4 PRO")

Note! The strongest suppression effect is achieved by combining BDA devices, for example, "BugHunter DAudio BDA-1" and "BugHunter DAudio BDA-4 PRO". This creates the most intense interference for recording when using devices equipped with AI filters.

Security measures

Despite the record power, "BugHunter DAudio BDA-1" is absolutely safe for people, as it generates sound frequencies that are practically imperceptible by ear. However, it should be taken into account that the collision of ultrasonic frequencies causes sound pops in the air. The ultrasonic power reaches record values of 135 dB. This means that the level of ultrasonic pressure at a distance of less than 3,3 ft (1 m) from the switched-on product may exceed the maximum permissible emission level safe for humans.

Follow the security measures:

• Do not point an operating device at a person's ear
• Pets are often sensitive to ultrasound, do not use the device in their presence if possible
• Do not cover the front panel or damage the transducers, as this reduces efficiency
• Do not give the device to children
