Noiseless Acoustic Safe ASU-20 "Safebox"

This video shows 2 things: the device provides 100% microphone suppression, but does not block radio frequencies, which allows to hear incoming calls and receive messages while the phone is inside the box.

Ultrasonic noiseless acoustic safe ASU-20 is designed to protect speech and any other acoustic information from leakage through smartphones, tablets and headsets.

The acoustic safe is a box made of natural wood with a built-in ultrasonic acoustic noise generator. The dimensions of the box allow to place up to 20 phones in it. Thanks to the use of powerful noise emitters in close proximity to the microphones of protected devices, reliable suppression of any acoustic information is ensured.

Unlike passive acoustic boxes and jammers, that turn on suppression only when the phone is active, a constantly working jammer in the ultrasonic acoustic safe guarantees 100% blocking of smartphones' and headsets' microphones . When the lid is closed, the box works silently. Reception of incoming calls and messages is not blocked. When the phones are in the box, the sounds of calls and messages are heard from the outside, and all external sounds inside the box are muted. The operating time of the acoustic safe is not limited.
