Functions of ultrasound

Ultrasonic noise is effective against eavesdroppers and bugs that record sound. The ultrasonic noise generated can completely overwhelm such microphones. The recording will be distorted, so no one will hear anything but noise. All confidential information will remain safe. Moreover, ultrasound is not audible, so it does not interfere with the flow of the meeting.


Acoustic noise

Protects you from eavesdropping methods where the ultrasonic noise is just not enough. Mainly, it protects against eavesdropping with a stethoscope microphone or laser microphone. The acoustic noise makes it impossible to listen to your conversation through the wall or the windowpane. Not even a third-party will be able to listen in on your conversation. Acoustic noise is basically a randomly generated mixed voice that creates a sound barrier. This is a unique solution – you can record your own voices and then generate them and have them overlap your conversation. Acoustic noise protects you even against the most cutting-edge forensic cleaning technologies.
