摘要
为探究长大公路隧道内噪声问题,文章探讨了隧道内主要噪声源及其识别测定方法,在噪声预测原理的基础上分析了隧道内降低车流声功率和增强隧道内表面吸声系数的降噪方法,提出了隧道内采用主动降噪技术和被动降噪技术的方案。结果表明,主动降噪技术的降噪效果可达3 dB以上,可定向改善检修人员作业环境;被动降噪技术在隧道内的应用模式为低噪声路面和壁面吸声材料,吸声材料的选取要考虑其吸收中低频声音的吸声系数,并适当加宽吸声频带,提高吸声系数,具有广泛的应用前景。
In order to explore the problem of noise in long tunnels, the main noise sources in the tunnel were analyzed and the measurement method was proposed. From the noise prediction principle, two methods to reduce the noise in the tunnel were proposed to reduce the sound power of the vehicle and to increase the sound absorption coefficient of the inner surface of the tunnel. The noise reduction effect of active noise reduction technology can reach more than 3 dB,and its application prospect in the tunnel is analyzed. The application modes of passive noise reduction technology in the tunnel are summarized as low noise road surface and wall surface acoustic absorption materials. The development of low noise road surface at home and abroad and its application prospect in China are analyzed.
