The new technology of control low-frequency noise, solves transformer station's low-frequency noise pollution, is research direction important at present.Existing indoor power transformation
The reduction of noise of standing is concentrated mainly in the process of soundproof door, noise reduction shutter etc..And to full indoor substation, noise reduction is installed and is inhaled
Sound wall can substantially shorten the room reverberation time, improve indoor hearsay condition, reduce indoor OA overall noise level, so as to reduce indirectly sound insulation
The Noise measarement value that door and window needs.
Common acoustic wall simple structure, typically using frame structure, fills a certain amount of sound-absorbing porous material and realizes sound absorption.
What sound-absorbing porous material was conventional has mineral fiber, polyurethane foam etc., and its low frequency absorption performance is typically poor, powder sintered plate,
Though the material such as foam metal aluminium effect of low-frequency sound absorption is good, material fabrication process is complicated, cost intensive, it is difficult to obtain on a large scale
Popularization and application.The simultaneously simple structure, sound sucting band are narrow.The sound absorption for being not particularly suited for transformer station's room noise is processed.
Aluminum fiber acoustic board light weight, thermal diffusivity are good, recycling capable of circulation, environmental protection, anti-moisture performance are good, and middle low frequency is inhaled
Acoustic performance is good, is increasingly used widely, but which there is also the narrow problem of sound sucting band, and perforation board resonance sound absorption structure
Sound absorption frequency selectivity is strong, can reach stronger acoustically effective for a certain special frequency channel.Therefore, can synthetic assembly it is convenient, plus
The requirement such as work forming module, light weight, realizes both have complementary functions by structure design, organically both combines closely,
The Environmental capacity of transformer station's noise is realized preferably.
The content of the invention
The purpose of this utility model is, in order to solve, existing acoustic wall is poor to low-frequency noise acoustically effective and sound absorption
The narrow problem of frequency band, the utility model disclose a kind of noise reduction acoustic wall.
The utility model realize technical scheme be, a kind of noise reduction acoustic wall include graphite plate, aluminum fiber acoustic board,
Inner air chamber, keel and body of wall.On body of wall, aluminum fiber acoustic board is laid on keel surface to keel installation；In aluminum fabric acoustic absorption
Plate surface lays graphite plate.Many places inner air chamber is formed between keel and aluminum fiber acoustic board.
The keel adopt cuboid framework structure made by light weight steel shape, its frame thickness (to be laid on body of wall
Thickness) determine as needed, the length and width of keel are determined according to metope size.
The graphite plate be evenly arranged penetration type absorb sound circular hole plasterboard, 3～5mm of thickness, 2～4mm of aperture,
The square arrangement of circular hole.Sound wave can be separated by the sound-absorbing hole, make which each resonance knot be entered from sound-absorbing hole respectively
Structure, facilitates the process of internal material and structure to sound wave.
The aluminum fiber acoustic board, thickness for the noise elimination air layer thickness that formed between 10～15mm, with body of wall be 90～
110mm, can cooperate with and produce the effect for absorbing each frequency band sound wave.
The aluminum fiber acoustic board is provided with sealing strip and adhesive layer with light steel type keel junction.
The beneficial effects of the utility model are that the utility model employs composite construction, when room noise incides sound absorption
During wall, it is distributed to up to aluminum fiber acoustic board by graphite plate, is on the one hand inhaled using the good middle low frequency of aluminum fiber acoustic board
Acoustic performance produces resistive absorption to sound, makes sound wave be converted into heat energy, on the other hand using the resonance sound-absorbing of air chamber entering one
Step reduces remaining acoustic energy, optimizes acoustically effective, and sound wave multiple reflections in the air layer is overlapped mutually and is consumed, from
And three-dimensional acoustically effective is produced, solve the problems, such as that effect of low-frequency sound absorption difference and sound sucting band are narrow well.
The utility model simple structure, it is easy to implement, it is adaptable to indoor location acoustic wall, not only can meet indoor power transformation
The requirement of characteristic noise of standing control, and fire prevention, excellent anti-corrosion performance, with low cost, long service life.
