DEVICE FOR VIBROACOUSTIC NOISE REDUCTION OF ROOM WITH ABILITY TO MONITOR TECHNICAL CONDITION Russian patent published in 2021 - IPC H04K3/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and electronics, in particular to means of creating artificial vibroacoustic interference and can be used to implement vibroacoustic noise in the protected premises and its enclosing structures. To achieve the result, the device for vibroacoustic noise noise of the room additionally contains a vibration-noise chamber rigidly attached to the outer body of the noise source, which contains spheres made of epoxy resin, the diameter of which is 1/20 of the volume of the vibration-noise chamber, and their number is selected based on the filling 1/3 of the volume of the vibration-noise chamber, and the vibration-noise chamber is made in the form of a transparent hemisphere.

EFFECT: invention provides opportunities for the formation of a secondary acoustic noise signal and visual control of the technical condition of the device.
