Adopt technique scheme, bloop on perforated plate and the air layer between perforated plate and film assembly define a perforation structure, its function eliminates mid-frequency noise, the frequency band that will eliminate can be adjusted by the size of adjusting hole and perforated percentage, the lower surface of perforated plate is wavy surface, to strengthen the reflecting effect of audio frequency, promote the effect of noise reduction; Elastic film in film assembly is separated into polylith, eliminates low-frequency noise by vibration, and adjust by the shape of grid in adjusting frame and size the frequency band that will eliminate, base plate can isolate high frequency noise.Thus realize the isolation of multiband noise.This sound insulation slab structure is simple, and soundproof effect is good.
Further, perforated plate is at least distributed with the different bloop of two kinds of diameter, to eliminate the noise on more wide-band.
Further, the first through hole is T-shaped hole.Conveniently stay bolt is installed, and the head of stay bolt can be hidden, attractive appearance.
Further, the thickness of elastic film is 0.1-1mm.The elastic film good muffling effect of this thickness.
Further, framework adopts organic glass or resin to make.This framework lightweight, is convenient to install.
Further, base plate is in square, and four edges of the lower surface of base plate are respectively provided with a groove, and groove extends internally from the sidewall of base plate, and the bottom of groove is provided with the first installing hole running through base plate; Four sidewalls of base plate are respectively provided with an outward extending lug, and each lug all with one groove is oppositely arranged, and each lug is equipped with second installing hole corresponding with the first installing hole on groove corresponding thereto.This employing structure, facilitates multiple sound insulation slab to collide, efficient and convenient, and installs firm.
The utility model also proposes a kind of noise reduction wall, and this noise reduction wall is spliced by above-mentioned sound insulation slab.
The noise of multiple frequency range can be eliminated or isolate to sound insulation slab described in the utility model, and can be assembled into noise reduction wall very easily, has very strong practicality.
