Purpose
ULTRAVOX-LB (LW)/24 (“chandelier”) is a professional device for protecting negotiations from recording by voice recorders, smartphones and hidden microphones, designed in the form of an elegant hanging chandelier.
The ULTRAVOX-LB/24 model is available in black, ULTRAVOX-LW/24 in white, allowing the device to be harmoniously integrated into various interior designs. It can be installed on any type of ceiling. Ideal for plasterboard and stretch ceilings. Can also be installed on dark ceilings.
The distinctive feature of the model is the increased effective suppression range thanks to the manufacturer’s patented technology: at an installation height of 2.8 m, the diameter of the interference zone on the floor is 2.3 m.
The device effectively counteracts unauthorized recording using:
- mobile, stationary and radio-frequency recording devices
- professional audio recording equipment
- hidden and external microphones
- mobile phones
Operating Principle
Ultrasonic Interference Generation
The device generates a complex signal in the ultrasonic range that is not perceived by the human ear.
24 ultrasonic emitters generate noise interference.
Effect on Microphones
The interference distorts the signal reaching the microphones, making voice recording unintelligible or completely impossible.
Limitations
Ultrasound does not pass through solid obstacles (walls, furniture, partitions), so for effective protection the device should be placed within the protected area.
