Abstract
A kind of efficient noise reduction road acoustic screen, constitute by support and acoustic screen body, said acoustic screen body comprises absorbing sound and lowering noise orifice plate, sound-absorbing and noise-reducing body and sound insulation and noise reduction layer, its special character is: be coated with the damping noise-reducing layer that is made of damping glue at sound insulation and noise reducing layer inner surface, said sound-absorbing and noise-reducing body adopts glass fibre cotton to make.Advantage is to have outstanding sound insulation and noise reducing effect, can effectively prevent to wear out, and makes sound-absorbing effect permanent, realizes efficient noise reduction.
Description
Technical field
The utility model belongs to sound arrester, particularly a kind of efficient noise reduction road acoustic screen.
Background technology
Various motor vehicles will produce the motor-driven noise of high strength about 80～100dB (A) along the line when highway or railway move, near the road if having residential block, office, various enterprises and institutions of school all will suffer the harm of the motor-driven noise of high strength.Noise is fearful invisible killer, and people live in the environment of high intensity noise for a long time, and it is bad not only to have a rest, and off color is easily suffered from hearing disorders such as deafness; Cause the direct misfortune hand of cardiovascular and cerebrovascular diseases such as the personnel that contact high intensity noise easily suffer from a heart complaint, blood pressure height especially.Because the characteristics of high strength motor vehicles noise are: frequency band broad 200Hz～10000Hz, the sound intensity is bigger.Therefore, to high strength motor vehicles noise, only take single absorbing sound and lowering noise or sound insulation and noise reducing can't realize effectively administering.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of outstanding sound insulation and noise reducing effect that has is provided, and can effectively prevent to wear out, and makes sound-absorbing effect permanent, realizes the efficient noise reduction road acoustic screen of efficient noise reduction.
The utility model is achieved in that it is made of support and acoustic screen body, said acoustic screen body comprises absorbing sound and lowering noise orifice plate, sound-absorbing and noise-reducing body and sound insulation and noise reduction layer, its special character is: be coated with the damping noise-reducing layer that is made of damping glue at sound insulation and noise reducing layer inner surface, said sound-absorbing and noise-reducing body adopts glass fibre cotton to make.
Above-mentioned efficient noise reduction road acoustic screen is provided with wave blinds opening on the absorbing sound and lowering noise orifice plate.
Above-mentioned efficient noise reduction road acoustic screen, the thickness of said damping noise-reducing layer is 1～2mm.
The utility model has the advantages that:
1, adopts damping glue as the damping noise-reducing layer, when the noise of 150～10000Hz passes through the damping noise-reducing layer, will produce the damping noise-reducing effect, the acoustic energy of the partial noise that decayed.
2, absorbing sound and lowering noise orifice plate antetheca adopts wave blinds opening, analyzes according to the noise that noise source is sent, and has outstanding sound insulation and noise reducing effect.
3, the sound absorption reduction body adopts the glass fibre cotton of highly durable character, can effectively prevent to wear out, and makes sound-absorbing effect permanent.
4, owing to adopt the comprehensive Noise Reduction technology can realize efficient noise reduction, its sound insulation factor can reach 30dB (A), and inserting loss is 9～11dB (A).
