Description
Technical field
It is more particularly to a kind of to be applied under air-flow environment the invention belongs to the technical field of acoustics sound-absorbing material/structure
Sound absorbing module.
Background technology
At present, there is sound-absorbing material in many places such as man-made noise improvement, room noise control, professional acoustical laboratories
Application.Traditional sound-absorbing material suffers from shortcomings, such as the sound sucting band of resonance sound-absorbing material is narrower, wedge absorber
It is highly suitable with the frequency band of effect, that is to say, that for low frequency sound absorption, it is necessary to considerably long wedge.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of sound absorbing module suitable under air-flow environment, reduce sound absorption
With good sound sucting band width while material thickness.
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of sound absorption suitable under air-flow environment
Module, including armour layer, filter layer, medium-high frequency absorbent treatment and low frequency absorption layer, the mask layer surface perforation, thickness are
0.8mm~2.0mm, the filter layer uses that fire-proof and damp-proof entrant sound filter material is made, thickness is 1.0mm~4.0mm, described
Medium-high frequency absorbent treatment is made of porous sound-absorbing material, and the low frequency absorption layer is by some low frequency absorption monomer matrix form splits
Formed, the low frequency absorption monomer is hollow rectangular structure, is internally formed channel of acoustic wave, the channel of acoustic wave is integrally in vertical
" S " type, if the channel of acoustic wave is separated into stem portion by dividing plate, the entering tone mouthful of each several part channel of acoustic wave is located at low frequency absorption list
The upper end of body, split forms integrative-structure to the armour layer, filter layer, medium-high frequency absorbent treatment and low frequency absorption layer from top to bottom.
As one kind of the invention preferred embodiment, filling sucting sound material in the channel of acoustic wave.
Used as the further improvement to above-mentioned implementation method, the sound-absorbing material is mineral wool, compacting cotton or melamine cotton.
Used as another preferred embodiment of the present invention, the armour layer uses metal material, gypsum or timber system
Into.
Used as another preferred embodiment of the present invention, the fire-proof and damp-proof entrant sound filter material of the filter layer is carbon
Fibrous material.
Used as another preferred embodiment of the present invention, the porous sound-absorbing material of the medium-high frequency absorbent treatment is rock
Cotton, melamine foamed cotton, mineral wool or compacting cotton.
As one kind of the invention preferred embodiment, the low frequency absorption layer is using plastics, metal, cement or gypsum
It is made.
Beneficial effect
Armour layer：Play a part of protection and entrant sound；
Filter layer：Protect the medium-high frequency absorbent treatment of lower floor and prevent medium-high frequency absorbent treatment from being escaped through armour layer, with mask
Layer combination has the effect that has a certain upgrade to low frequency absorption；
Medium-high frequency absorbent treatment：Centering high-frequency sound energy absorption efficiency is high, for audio frequency high in absorption；
Low frequency absorption layer：Low frequency acoustic energy is entered into inside low frequency absorption monomer 5 by entering tone mouthful, by its internal " S " type
Channel of acoustic wave design, make it that the efficient absorption to low frequency acoustic energy is reached with the thickness of very little.In addition, by adjusting channel of acoustic wave
Opening and inner passage acoustic impedance, be allowed to be matched with the characteristic impedance of air, while adjusting other specification, such as passage aspect
Height, absorb sound thickness of unit etc., adjusts sound sucting band and acoustically effective.
Therefore, the present invention reduces the thickness of sound-absorbing material on the whole, meanwhile, for medium-high frequency acoustic energy and low frequency acoustic energy
Sound absorption treatment is carried out respectively, with good sound sucting band width.

Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
A kind of sound absorbing module suitable under air-flow environment as shown in Figure 1, including armour layer 1, filter layer 2, medium-high frequency
Absorbent treatment 3 and low frequency absorption layer 4.
The surface of armour layer 1 perforate, be made of metal material, gypsum or timber, thickness is 1.0mm, play protection and
The effect of entrant sound.
Filter layer 2 is made of fire prevention, the moistureproof, carbon fibre material that sound transparency is good, filterability is good, and thickness is 2.0mm, is protected
Protect the medium-high frequency absorbent treatment 3 of lower floor and prevent medium-high frequency absorbent treatment 3 from being escaped through armour layer 1, combined with armour layer 1 and low frequency is inhaled
