Acoustic noise generator Tambourine

The "Buben" product is used to protect confidential negotiations by creating acoustic interference.

The "Buben" can operate in either of two modes:
- generating speech-like interference,
- generating "white noise" interference.

Mode - speech-like interference:
In this mode, the product generates interference, the effect of which leads to the "destruction" of the meaning of individual phrases and sentences when converting a speech signal into an electrical copy using acoustic monitoring devices of all types (dictaphones, radio bugs, wired microphones, stethoscopes, etc.). In this case, the principle of recording or transmitting a speech signal in a specific acoustic monitoring device is irrelevant.

"White noise" mode:
In this mode, the product generates interference, the effect of which leads to the creation of noise interference when trying to record or listen to an acoustic signal using covert information collection devices. In this case, the principle of recording or transmitting a speech signal in a specific acoustic monitoring device is irrelevant.

Compared with "white noise" generators, the use of a speech-like interference generator provides an energy gain of several dB. That is, the specified reduction in the intelligibility of the protected conversations is ensured with a lower level of masking noise. If the negotiation regulations require the use of a "white noise" generator, it is recommended to use this mode.

Product Features:
• Small dimensions and autonomy of operation allow the device to be quickly used during negotiations not only in confined spaces - indoors, cars, but also in open areas.
• When using the product in the speech-like interference mode, a person is exposed to a much less tiring and irritating effect compared to the acoustic white noise mode.
• Four fixed volume levels.
• Indication of the volume level and battery discharge level.
• The product is made in a lightweight aluminum shockproof case.
• It is possible to use an external DC power source of any polarity.

The standard package includes the main unit, three AA batteries, and an operating manual.
