PAGE PAGE 21 某小区泵房噪声控制方案设计 摘要：随着社会的高速发展，人们对生活品质的追求越来越高，噪声污染开始受到人们的重视。通过吸声材料和吸声结构来降低噪声的技术称为吸声。吸声降噪是目前控制室内噪声的一种常见措施。本设计噪声治理的目标是降低泵房噪声，改善住宅区声环境质量。该小区泵房的噪声标准需满足《声环境质量标准》（GB3096-2008）的1类标准。为了使泵房噪声降低到限值，本次设计采用吸声材料和吸声结构相结合的方式来降噪。由于泵房内环境比较潮湿，且考虑到安全问题，因此吸声材料（结构）应具有防火、防蛀、防潮、耐热、耐腐蚀等特点，故本设计中的吸声材料为超细玻璃棉，吸声结构为穿孔石膏板。 本次设计针对的是某小区的泵房，在实地测量的基础上，根据相关的法律法规和标准，对吸声材料和吸声结构进行设计计算，并绘制CAD图纸。 关键词：噪声；水泵；吸声；超细玻璃棉；穿孔石膏板 Pump House Noise Contral Design of a Residential Community Abstract: with the rapid development of society,the pursuit of the quality of life is getting higher and higher,and the noise pollution has been paid attention to by people.The technology of reducing noise by sound absorption material and sound absorption structure is called sound absorption.Sound absorption and noise reduction is a common measure to control the indoor noise at present.The goal of this design is to reduce pump noise,and improve the acoustic environment quality of residential distinct.The noise criterion of the district pump house is required to meet first class standards of”Environmental quality standard for noise”(GB3096-2008).In order to make the pump noise reduce to the limit，this design uses a combination of sound-absorbing material and sound-absorbing structure to reduce noise.Due to the environment of the pump house is moist,and taking into account security issues,and sound-absorbing materials(structure) should be with fire prevention,anti-moth,Mois- ture resistance,heat resistance,corrosion resistance and other characteristics,so the?design of sound absorption material is superfine glass cotton,and the sound absorption structure is perforated gypsum board. This design aims at the pump house of the residential community，on the base of field measurement, and according to relevant laws and standards, and gets the design calculation of the sound absorption material and structure, then draw CAD blueprint.
