【摘要】：采用专业噪声监测及频谱分析设备对上海虹桥机场附近华美地区既有住宅的室内外声环境进行监测,结果表明,室外噪声主要集中在2×103Hz范围的中低频段,现有门窗、墙体及室内布置条件下房间具有一定降噪效果,但室内噪声仍不满足规范规定的限值要求;提出适用于机场附近既有住宅的室内噪声控制技术建议,包括更换隔声门窗、墙体改造等;根据实际条件对华美地区既有住宅进行隔声降噪改造技术应用。实测结果表明,改造前后住宅室外声环境噪声差别不大,室内噪声满足规范限值的要求,室内外声级差比改造前提高2.2~8.6d B,改造对125~500Hz噪声具有明显改善效果;隔声改造后评估结果表明,飞机起飞或下降时,关窗后室内噪声明显改善,改造后居民楼立面整齐美观,保温效果增强,但通风效果略有下降,总体反应比较良好。所提出的室内噪声控制技术具有较好的适用性和有效性,可为我国机场附近既有住宅隔声降噪改造提供技术参考。
[Abstract]:The indoor and outdoor acoustic environment of the existing residential buildings near Shanghai Hongqiao Airport is monitored by professional noise monitoring and spectrum analysis equipment. The results show that the outdoor noise is mainly concentrated in the low and medium frequency range of 2 脳 103Hz, and the existing doors and windows are used. Under the condition of wall and indoor layout, the room has a certain effect of noise reduction, but the indoor noise still does not meet the requirements of the limit stipulated in the code. The paper puts forward some technical suggestions for indoor noise control which are suitable for the existing residential buildings near the airport, including the replacement of sound insulation doors and windows, the reconstruction of walls, etc. According to the actual conditions, the technology of sound insulation and noise reduction is applied to the existing residential buildings in Huamei area. The measured results show that there is little difference in the noise of outdoor sound environment before and after the renovation, and the indoor noise meets the requirements of the code limit, and the difference of the indoor and outdoor sound levels is increased by 2.2 ~ 8.6dB compared with that before the renovation, and the modification has obvious improvement effect on the 125~500Hz noise. The evaluation results after sound insulation modification show that the indoor noise is improved obviously after the take-off or fall of the aircraft, the elevation of residential buildings is neat and beautiful after the transformation, the insulation effect is enhanced, but the ventilation effect is slightly decreased, and the overall response is relatively good. The proposed indoor noise control technology has good applicability and effectiveness, and can provide a technical reference for the reconstruction of sound insulation and noise reduction of existing residential buildings near the airport in China.
