Description
Technical field
The utility model is related to Noise measarement sound barrier panel, especially a kind of highway sound-screen of use series-parallel connection sound absorption structure
Baffle.
Background technology
The today developed in expressway around city, highway, railroad noise have had a strong impact on the normal life of nearby residents, have been
Reduction noise pollution, sound barrier is often built by highway side, the railway to solve problem of noise pollution.At present, sound barrier
Plate is typically fabricated by using metal material or nonmetallic materials, but its it is maximum the problem of be in can not effectively absorbing, it is low
The traffic noise of frequency.
Through actual measurement, the noise peak of highway division, in 60Hz or so, is in stable state in 250Hz to 2KHz is interval,
After 2KHz, traffic noise rapid decay, this absolutely proved the traffic noise of highway division be mainly in, low-frequency noise, and
The sound pressure level highest of low-frequency noise, for highway division sound barrier should possess absorb in, the ability of low-frequency noise, so
And, current road sound barrier often only with mineral wool as sound-absorbing material, in this kind of sound barrier, low frequency absorption performance compared with
Difference.
Furthermore, because road sound barrier is limited by cost of investment, so road sound barrier can not possibly use expensive
Multilayer microperforated panel soundabsorbing construction.
Research shows, either the sound absorbing mechanism curve that still absorbs sound has very for polymer particle sound absorption and microperforated panel sound absorption
High similitude, microperforated panel sound absorption theory thinks, when micro-pore diameter is 0.1mm, can obtain very wide sound sucting band, surpass
Microwell plate resonance sound-absorbing structure has broadband, the characteristic of high-frequency absorption, the use of ultra micro soundabsorbing construction is to improve sound absorption effect
An important channel for fruit, the acquiring technology of micropore diameter perforated plate is to be microperforated panel resonance sound-absorbing structure by theoretical conversion
The key technology of practical application, still, at present used in various manufacture ultra micro orifice plates technologies it is also very immature because will be
Ultramicropore of the millions of apertures in 0.1mm or so is processed on every square metre of plate, its difficulty of processing is very big, processing cost
Height, and its manufacturability is not also high, so needing further to develop.
In order to solve this problem, many researchers are hardened by using series connection microperforated panel structure or micropunch in parallel
The method of structure widens the sound sucting band of sound absorber, and practical study also indicated that using double-deck or multilayer microperforated panel structure（String
It is coupled structure）The sound sucting band of sound absorber can significantly be widened；The resonant frequency of resonance sound-absorbing structure is relevant with the thickness of cavity,
, so can be with then its resonant frequency is not just a single value if the thickness of the cavity of a sound absorption structure is different
Widen the resonance sound-absorbing frequency band of whole sound absorption structure, so that the purpose of broad band sound absorption is reached, several different-thickness cavitys
The sound absorber that sound absorption unit is formed in parallel is referred to as micropunch sound absorber in parallel；Experimental data shows, after multiple microperforated panels are in parallel,
It combines acoustic absorptivity and multiple absorption peaks occurs, absorbent properties are greatly improved, and absorption peak is significantly improved, and inhales
Frequency range is received significantly to increase.
But either parallel-connection structure or cascaded structure, it is required for using double-deck or multilayer Micropunch Acoustic Board, so
The cost of sound absorption structure can be made very high, meanwhile, in order to realize this cascaded structure or parallel-connection structure, it is necessary to using corresponding
Complex attachment structure, this also can make technique become more complicated, the cost of sound absorber is further increased, this
Namely why microperforated panel parallel-connection structure or cascaded structure not by the widely used immediate cause of engineering.
It is pointed out that in research in the past to microperforated absorber, do not occur also cascaded structure with it is in parallel
" hybrid connected structure " that structure is combined, this is reason, to realize hybrid connected structure gesture, must make the structure of sound absorber and become more multiple
It is miscellaneous, so that the cost of sound absorber remains high.
In addition, applicant have submitted an Application No. on December 5th, 2015 to State Intellectual Property Office
2015109291613, the patent of invention of entitled " polymer particle sound absorber ", the polymer particle sound absorber is shaped as plate
Shape, one side surface is the cylinder that another side surface rises and falls for plane or with same rule with the regular cylinder risen and fallen,
And in polymer particle sound absorber, provided with the corresponding hollow structure of each fluctuating, based on the unique understanding to this kind of structure and
Practice, applicant investigated the hybrid connected structure road sound barrier plate of the present invention.
