Ultrasonic voice recorder jammer aimed to prevent you from unsanctioned recording on digital voice recorders, Dictaphones, smartphones and other voice recording devices.

This jammer can be used where negotiations and talks take place. The unique feature of this unit is that it has 48 ultrasound emitters, which are placed in circle for jamming any voice recording devices around the jammer.

Due to its formation we could achieve 10 meter suppression around the jammer.

This range however depends on voice recording device and its quality. Jammer works as a directional ultrasonic suppressor, inflicting jamming on voice recording device’s microphone membrane, which makes impossible to record or comprehend your conversation within jammer range. Additional acoustic jamming creates noise background which is human-like speech, which can be adjusted. In case when your conversation was recorded, the record will contain lots of voices making it harder to distinguish a single one.
