| description | FIELD: construction. ^ SUBSTANCE: invention pertains to industrial acoustics, in particular, to wideband noise control and may be employed in all branches of industry for noise control of the industrial equipment by sound absorption. Noise absorbing piece element of the manufacturing facility contains a perforated wall and a sound absorber. Sound absorber is arranged in two layers, harder one whereof is solid and profiled, the other softer one is made intermittent and is located under the surfaces of the first layer. The element is equipped with piece elements of sound absorber. Sound absorbing element of the facility contains a frame, window and door openings, openings for installation of lamps and acoustic enclosures made as hard and perforated walls, in between whereof there is sound absorbing material. Main reactive resonance insert is fixed on the inner side of the frame of the piece elements of sound absorbers. It is made in the form of a cylindrical surface divided by walls with openings serving as Helmholtz resonators throats, set in series; and around the main reactive resonance insert there are, at least, two additional reactive resonance inserts, each whereof is made in the form of cylindrical surface divided by walls with resonance openings serving as Helmholtz resonators throats. Axes of additional reactive resonance inserts are set along horizontal plans of at least two circles, center whereof coincides with the axis of the main reactive resonance insert. ^ EFFECT: increased efficiency of sound absorption due to widening of frequency range and secondary absorption of sound waves reflected from the sound damper. ^ 3 cl, 2 dwg |
