PURPOSE
Speech information security device «Priboi» is used for security of rooms to prevent information leak (speech) through acoustic and vibrational channels.
Uses automatic control of noise contamination level from the volume level of the speech.
TECHNICAL CHARACTERISTICS
| Frequency range of masking signals as «white noise» + «speech-like signals», Hz | 125...8000 |
| Correlation «white noise» + «speech-like signals», dB | 0, +3, +6 |
| Range of reproducible frequencies of vibration transformer, Hz | 125...8000 |
| Range of reproducible frequencies of acoustic transformer, Hz | 125...8000 |
| Output power from acoustic channel, W, no less than | 15 |
| Output power of any of three vibration channels, pcs., no less than | 6 |
| Number of connected vibration transformers to every channel, pcs., no less than | 30 |
| Number of connected acoustic transformer, pcs., no less than | 10 |
|
Sensitivity of external microphone in the frequency range from 200 to 4000 Hz with built-in amplifier, V/Pa, no less than |
10 |
APPLICATION SCHEME
- creation of masking signals in leak channels («white noise», «speech-like signals», «white noise» + «speech-like signals»), which correspond to the formal qualities of speech (signals can be adapted to a specific person)
COMPLETED WITH
- acoustic transformers (no less than 10 pcs.)
- vibroacoustic transformers (no less than 30 pcs.)
SERVICES
- installation and maintenance of the device
