Important

When using an ultrasonic generator to drown out microphones in close proximity, certain limitations arise due to the laws of physics. Some microphone designs are more prone to jamming than others, so effectiveness can vary by microphone type. Depending on this, the maximum effective range of the generator can fluctuate several times. In addition, the generated ultrasound is reflected from the surface and is not able to pass through most materials to an excessive depth. For this reason, it is recommended to use a sufficient number of devices and then place them appropriately in the given room to ensure the best possible privacy during negotiations and meetings. The highest possible quality of interference is achieved thanks to the Acoustic Noise function, which allows you to record your own voice and cover your conversation with it. The recorded voice is then randomly generated, creating a sound barrier against eavesdropping by a stethoscope microphone or a laser eavesdropper. In addition, it protects against the most modern methods of forensic cleaning of the voice recording. Although the device does not guarantee 100% muting efficiency, it surpasses competitive solutions. Thanks to its configuration, it guarantees high efficiency against microphones on devices such as voice recorders, bugging and seismic microphones, microphones on computers, headsets, cameras and mobile phones.
