Abstract
The invention relates to a sound insulation structure with a perforated plate. The sound insulation structure with the perforated plate mainly consists of an upper panel, a lower panel, the perforated plate and side panels. Four sides of a space between the perforated plate and the upper panel and a space between the perforated plate and the lower panel are plugged by the side panels to form two chambers. The two chambers and the perforated plate form resonant silencing structures respectively. In the sound insulation structure with the perforated plate, the upper panel, the lower panel and the side panels are blind plates without perforations. The distance between the perforated plate and the upper panel and the distance between the perforated plate and the lower panel can be equal or unequal.
Description
Technical field
The present invention relates to a kind of sound insulating structure, relate in particular to a kind of sound insulating structure that has perforated plate.
Background technology
Adopting opacity technique effectively must cut off the noise transmission approach, is the conventional means of noise control.Sound insulating structure commonly used at present has individual layer to spare matter thin plate, the compound sound insulating structure of individual layer, doubling plate sound insulating structure, multiple light-duty sound insulating structure, the heavy partition wall of individual layer, double-deck heavy partition wall and multilayer sound insulating structure.Common partiting sound member such as door and window, body of wall, floor etc., can belong in the above sound insulating structure.
Perforated plate is commonly used to cooperate with back air space and constitutes the resonant silencing structure.In order to widen sound sucting band, sound absorption materials such as filling glass cotton, asbestos, porous foam often in the back air space of perforation board resonance sound absorption structure.Microperforated panel refers generally to thickness of slab, aperture all less than 1 millimeter, and perforated percentage is 1%～5% metal sheet.Adopt microperforated panel to match and to constitute the microperforated panel resonance sound-absorbing structure with air layer behind.Perforation board resonance sound absorption structure and microperforated panel resonance sound-absorbing structure all are mainly used in the surface of sound absorber or sound-proof wall in noise control engineering at present, be used for absorbing noise in the space, reduce reverberation, thereby reduce noise in the space, perhaps improve the sound insulation factor of sound-proof wall.
Though it is a variety of that the kind of present compound sound-proof wall has, these sound insulating structures mostly are made of the plate and the sound absorption material of not tape punching, and perhaps a surface portion at sound insulating structure uses perforated plate resonant silencing structure.Because the composite board compound tense can exist coincidence effect and resonance effects, the sound insulation factor that the existence of these two kinds of effects has just limited sound insulating structure commonly used improves; Especially the sound insulation factor that has limited the product that partly insulates against sound improves, such as sound proof window.Therefore, existing sound insulating structure also exists a lot of deficiencies and needs to improve part.
