摘要: 通过现场声级测量,掌握了高速公路隧道的噪音声级水平;利用计算机多媒体技术对隧道内的噪音进行了频谱分析和波形识别。研究结果表明,铺有混凝土路面的隧道噪音波形为矩形波,而铺有沥青路面的隧道噪音波形为正弦波,两种路面的噪音频率分布在频谱图上的区别明显。研究结果对提高隧道内的行车安全性和舒适性很有意义。

Abstract: Through the noise level tested by fieldwork,the noise level of highway tunnel is griped.Using multimedia technology,noise frequency character analysis and the waveform identification are carried out.The result shows that noise wave-form of cement concrete pavement is rectangular wave and asphalt concrete pavement is sine wave.The noise spectrum graphs of the two kind of pavement have obvious differences in distribution.The study is significant to improve the safety and comfort of driving in tunnel.

Key words: tunnel, noise, frequency character, waveform
