INDOOR VOICE DATA PROTECTION SUIT «ECH»



 

 

 

 

 

 

PURPOSE

Indoor voice data protection suit «Echo» is used for measuring and calculating characteristics of sound insulation and vibration insulation of areas/rooms, as well as for the estimation of the security level from speech information leakage through vibration and acoustic channels.

The complex consists of a noise source and a sound measuring device. The noise source includes acoustic radiator and noise generator. The sound measuring device includes a calibrated microphone, two calibrated accelerometers and a block with converters.
