Digital noise generator SNHP-400 emits white noise with variable random parameters, works with Piezo emitters or acoustic loudspeakers to create a system protecting a room from the leakage of confidential information.

Human speech is the oldest and most important means of disseminating information among people. The unprocessed voice, i.e. the original signal, is equivalent to a handwritten signature. Current technologies, such as laser and infrared microphones, or contact microphones, enable unauthorized interception of confidential information from longer distances, even through various types of partitions, such as windows or walls.
Digital noise generator SNHP-400 with randomly changing parameters of white noise emission works together with acoustic loudspeakers or Piezo emitters, which transform electrical energy into vibroacoustic vibrations creating noise in the frequency of human speech signal. The generator emits a white noise vibroacoustic signal, which is propagated through the transducers, creating a kind of cage inaccessible from the outside.
The digital noise generator has 4 channels, to each of which can be connected 100 Piezo transmitters, 25 per channel, and 48 loudspeakers, 12 per channel. The effective radius of jamming from one transducer is about 1 m.2.
