Acoustic noise generator
Voice leakage protection device
This device is designed to protect from leakage of voice information through random or specially organized channels by setting acoustic
interference, critically worsening the intelligibility of the protected acoustic signal when recording it on various media or transmitting through various communication channels. Specially organized channels may include various technical means and systems for the collection and transmission of acoustic information, such as voice recorders, wireline or radio microphones of stationary and mobile types, etc.
The device has three modes of noise emission, characterized by comfort, the principle of formation (correlated, uncorrelated) and type (“white noise”, speech-like interference). The volume regulator provides five volume levels of the emitted interference.
When turning off the device power, it is possible to save the last mode and volume level in the memory. The device has a built-in speaker and microphone, as well as a linear output for connecting external amplification devices and sound output (for example, computer speakers).
The device can be operated both from the power supply and from the built-in Li-ion battery, which allows you to work offline for up to 10 hours continuously and up to 15 hours in the mode of correlated interference (VOX). When working from the power supply, the battery is simultaneously charged.
