摘 要:现行建筑隔声评价标准采用计权隔声量作为建筑隔声单值量,但过往研究发现,基于声压级差的隔声参量与主观感受的隔声效果之间仍存在差异。利用六种不同的建筑构件对三种噪声源的隔声结果,进行建筑隔声特性与响度级差之间的关系分析。结果表明,计权隔声量这一单值量可以在一定程度上体现人的主观感受,但并没有一种单值量可适用于评价各种噪声源所产生的响度级差。对于中高频较丰富的白噪声,不同构件产生的响度级差的差异较大,对于低频较丰富的交通噪声,不同构件产生的响度级差的差异较小。相比之下,R_(w)+C_(100-3150)有可能更适合描述交通噪声的响度级差。对于隔声单值量高且隔声频率特性斜率大的建筑构件,可能会出现主观隔声效果不够理想的问题。The current rating standard of sound insulation in buildings adopts the weighted sound reduction index as the single value of sound insulation,but the previous research has found that the weighted sound reduction index cannot fully reflect the subjective perception of sound insulation.This paper analyzes the relationship between the building sound insulation characteristics and the loudness level difference using the sound insulation results of six different building components to three types of noise sources.The results show that the single-valued quantity of weighted sound reduction index can reflect subjective perception to a certain extent,but no single-valued quantity can be used to evaluate the loudness level difference generated by various noise sources.For the white noise with abundant middle and high frequencies,the variance of loudness level differences generated by different components is larger;and for the traffic noise with abundant low frequency,the variance is smaller.The index of R_(w)+C_(100-3 150) is more suitable for describing the loudness level difference of traffic noise.For building components with large single value of sound insulation and steep sound insulation frequency characteristics,the subjective effects of sound insulation may be unsatisfactory.
