FIELD: information protection.
SUBSTANCE: invention is intended to protect speech information from laser interception through the window. The essence of the invention lies in the fact that the window glass is covered with a light-transmitting-diffusing curtain located inside the room, the curtain and window glass are excited by masking vibration by means of vibration exciters connected to a vibrating rail touching the lowered curtain, and in the non-working position the curtain is wound on a shaft, while the vibrating rail elastically attached to the brackets, by means of which the curtain shaft is hung on the window frame, or window niche, or wall.
EFFECT: reduced parasitic acoustic noise and improved protection reliability.
