ULTRAVOX-D
Short description
The ULTRAVOX-D (“Diary”) series device is the flagship portable solution for protecting conversations from unauthorized audio recording. A system of 24 ultrasonic emitters creates a powerful interference signal for voice recorders, smartphones, and hidden microphones. The premium leather-bound ULTRAVOX-D design allows for discreet use in the office, in the car, or during meetings. It features silent operation, remote control, and up to 3 hours of battery life.

Purpose
The ULTRAVOX-D series device is designed for reliable protection of confidential conversations by suppressing voice recording.
It can be used in offices, cars, meeting rooms and other areas where information protection is required.
For protection of large spaces and maximum effectiveness, it is recommended to use several ULTRAVOX devices simultaneously.
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 located on three sides generate noise interference.
Effect on Microphones
The interference distorts the signal reaching the microphones, making voice recording unintelligible or completely impossible.
The interference acts directly on the microphone membrane, creating a “speech chorus” effect that renders the recording unusable.
Limitations
Ultrasound does not pass through solid obstacles (walls, furniture, partitions), so for effective protection the device should be placed within the protected area.
