Description
Technical field
The utility model relates to a kind of speedway sound insulation and noise reduction shade curtain.
Background technology
The noise that the noise that urban road traffic vehicles produces, building operations produce etc. noise pollution brings very large impact to the work of people, life, bring harm even to the health of people, especially viaduct both sides, road both sides for this reason, and for intercepting noise around building site, need to arrange some sound insulating panels, to reduce traffic or the interference of live to surrounding resident of building noise, in road design construction in recent years, also pressure arranges sound insulating panel.Many alloy sheets, the aluminium sheet encapsulation damping materials of selecting of current sound insulating panel are made, and sound-absorbing, soundproof effect are limited, and cost is higher; This sound barrier lacks effective sound absorption function, and sound-absorbing, soundproof effect are undesirable, and aluminium sheet cost is higher, is corroded and affects the life-span.
Sound insulation to refer to by certain article sound or Noise insulati on, partition, separation etc., therefore just needs sound insulation materials.The decibels that the incident acoustic energy of material side is relevant to the transmission acoustic energy of opposite side is exactly the sound transmission loss of this material, usually represents with symbol R (dB).Sound insulation materials or component, can be different because of use occasion, and method of testing is different and the soundproof effect that draws is different.For sound insulation materials, transmission acoustic energy be weakened, the propagation of block sound, just can not as damping material porous, loose, ventilative, its material should be heavy and closely knit on the contrary, as class materials such as steel plate, stereotype, brick walls.The requirement of sound insulation materials material is closely knit imporosity or gap; There is larger weight.Because this kind of sound insulation materials is closely knit, be difficult to absorb and reflect through acoustic energy energy strong, so its sound absorption qualities is poor.Sound insulation materials can make transmission sound energy attenuation to the 10-3 ~ 10-4 or less of incident acoustic energy, and for convenience of expressing, its sound transmission loss method of measurement of decibel represents.
Current, noise has become a kind of main environment pollution, and the acoustic environment problem of building is more and more subject to concern and the attention of people.Suitable material is selected to carry out sound-absorbing to building and sound insulation process is one of the most basic the most frequently used technical measures in building noise control engineering.
Owing to being short in understanding to the means of Noise measarement, " sound-absorbing " and " sound insulation ", as diverse concept, has usually been confused.Glass wool, rock mineral wool one class have good sound absorption qualities but the very poor material of sound insulation value is corruptly called " sound insulation materials ", and some are that the abatvoix that raw material is made is named as " sound insulating panel " and sound insulation problem in order to solve building with string in one's early years.In order to reasonable employment material, improve building Noise measarement effect, have " sound-absorbing " and " sound insulation " these two concepts and understand further and clear and definite necessity.The difference of material sound-absorbing and material sound insulation is, material sound-absorbing is conceived to the size of sound source side reflection of the acoustic energy, and target is that reflection of the acoustic energy is little.Damping material absorbs the decay of incident acoustic energy, generally only has a few tenths of, and therefore, its sound absorbing power and sound-absorption coefficient can represent decimally; Material sound insulation is conceived to the size of the transmission acoustic energy of incident sound source opposite side, and target is that transmission acoustic energy is little.Sound insulation materials can make transmission sound energy attenuation to the 10-3 ~ 10-4 or less of incident acoustic energy, and for convenience of expressing, its sound transmission loss method of measurement of decibel represents.Damping material is very little to the reflection of incident acoustic energy, this means that acoustic energy easily enters and through this material; The material of this material should be porous, loose and ventilative, Here it is typical porosity damping material, in technique normally with threadiness, graininess or expanded material to form cellular structure; Architectural feature is: have in material a large amount of, interpenetrate, from table to inner micropore, also namely there is certain gas permeability.When sound wave incident is to porous material surface, cause the air vibration in micropore, due to viscous resistance and the conduction of heat of frictional resistance and air, quite a few acoustic energy is converted into heat energy, thus plays sound absorption.Sound insulating panel now with damping material is generally all made up of sealing metal plate and the stratum granulosum be arranged on sealing metal plate, the air vibration effect on such sound insulating panel self and stratum granulosum surface is bad, in the place that noise is comparatively large and noise occurrence frequency is high, the noise reduction of sound insulating panel is good not, and the heat energy that acoustic energy changes into also cannot shed as soon as possible from sound insulating panel.
