PURPOSE
Speech information security device «Priboi» is used for security of rooms to prevent information (speech) leakage outside the security zone through acoustic and vibrational channels.
This device has automatic control of noise contamination level depending on the volume level of the speech.
TECHNICAL CHARACTERISTICS
| Types of masking signals: “white noise”, a combination of “white noise” and “speech-like signals” | |
| Frequency range of masking signals, Hz | 175...8000 |
| Range of reproducible frequencies of vibration transformer, Hz | 175...5700 |
| Range of reproducible frequencies of acoustic transformer, Hz | 175...5700 |
| Number of independent channels | 4 |
| Number of connected acoustic transformer, pcs., no less than | 10 |
| Number of connected vibration transformers to every channel, pcs., no less than | 30 |
APPLICATION SCHEME
- creation of masking signals in leak channels (“white noise”, a combination of “white noise” and “speech-like signals”), which correspond to the formal qualities of speech (speech-like signals can be adapted to a specific person)
DELIVERY SET
- acoustic transformers
- vibration transformers
- external microphone
- remote control panel
SERVICES
