基于声漫步法的包头市五当召景区声景观研究

Research on Soundscape of Wudang Lamasery Scenic Area in Baotou City based on Soundwalks

文章以包头市五当召景区作为研究对象,采用声漫步的方法,对其进行了声环境实测,并将现场录制的声音导入Multi-Instrument软件中进行声学参数分析,最后使用SPSS软件分析了声景和视觉景观以及声学参数之间的相关性。结果表明,景区内声景可分为自然声(48.7%)、生活声(23.2%)和人工声(28.1%)三大类;声景多样性(SDI)为0.79;人们最喜欢自然声中的"鸟叫"和"虫鸣";景区各测点平均等效A声级为50.1d B;声景的舒适度与声景安静度、声景类型、空间尺度、声音的响度和尖锐度都存在显著相关性。

The paper taking Wudang Lamasery Scenic Area in Baotou City as the research object,using the soundwalk approach,the sound environment is measured,and the recorded sound is imported into Multi-Instrument software to analyze the acoustic parameters.And finally use SPSS to analyze the correlation between the soundscape and the visual landscape and the acoustic parameters.The results show that the soundscape in scenic area can be divided into three categories:natural sound(48.7%),life sound(23.2%)and artificial sound(28.1%);the soundscape diversity index(SDI)is 0.79;people like nature most"Birds"and"worms"in the sound;the average equivalent A sound level of each measuring point is 50.1 d B;the comfort and quietness of the soundscape,the soundscape type,and the spatial scale There is a significant correlation between the loudness and sharpness of the sound.
