Purpose
The ULTRAVOX-SP series device is designed for reliable protection against the leakage of acoustic information. It is the most powerful device in its class on the market. The device is installed into a suspended ceiling directly above the conference table.
A distinctive feature of the model is its increased effective suppression range due 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.
Convenient control via wired and wireless remote control (up to 10 m in direct line of sight).
For protecting large rooms and achieving maximum effectiveness, it is recommended to use multiple ULTRAVOX-SP devices simultaneously. The units operate synchronously.
The device effectively counteracts unauthorized recording using:
- mobile, stationary, and radio-frequency recording devices
- professional audio recording equipment
- hidden and remote microphones
- mobile phones
Operating Principle
Generation of ultrasonic interference
The device generates a complex signal in the ultrasonic range that is not perceived by the human ear.
24 ultrasonic emitters, positioned on three sides, generate noise interference.
Effect on microphones
The interference distorts the signal received by microphones, making speech recordings unintelligible or completely impossible. The interference acts directly on the microphone diaphragm, creating a “speech choir” effect that makes recordings impossible to restore.
Limitations
Ultrasound does not pass through solid obstacles (walls, furniture, partitions), therefore for effective protection the device must be placed within the protected area.
