Previous studies indicate that residents may benefit from a "quiet side" to their dwellings. The influence of the level of road traffic noise exposure at the least exposed side on road traffic noise annoyance was studied in Amsterdam, The Netherlands. Road traffic noise exposure was assessed at the most and least exposed façade (Lden,most and Lden,least respectively) of dwellings for subjects in a population based survey (N = 1,967). It was investigated if and to what extent relative quietness at the least exposed façade affected the level of road traffic noise annoyance by comparing two groups: (1) The subgroup with a relatively quiet façade; (2) the subgroup without a relatively quiet façade (large versus small difference in exposure between most and least exposed façade; DIF ≥ 10 dB and DIF < 10 dB respectively). In addition, it was investigated if and to what extent Lden,least affected the level of road traffic noise annoyance. Results indicate a significantly lower road traffic noise annoyance score at a given Lden,most, in the subgroup with DIF ≥ 10 dB versus DIF < 10 dB. Furthermore, results suggest an effect of Lden,least independent of Lden,most. The estimated size of the effect expressed in an equivalent change in Lden,most approximated 5 dB for both the difference between the two subgroups (DIF ≥ 10 dB and DIF < 10 dB), and for a 10 dB change in Lden,least.
先前的研究表明，居民可能会受益于住所的“安静一侧”。本研究在荷兰阿姆斯特丹，调查了住所最不暴露面（Lden,most 和 Lden,least）的道路交通噪声暴露水平对道路交通噪声烦恼的影响。对于一项基于人群的调查中的受试者（N = 1,967），评估了住宅最暴露面和最不暴露面的道路交通噪声暴露情况。通过比较两组来研究最不暴露面相对安静是否以及在何种程度上影响了道路交通噪声烦恼的水平：（1） 相对安静的 façade 的亚组；（2） 没有相对安静的 façade 的亚组（最暴露面和最不暴露面之间的暴露差异较大；DIF ≥ 10 dB 和 DIF < 10 dB 分别）。此外，还研究了 Lden,least 是否以及在何种程度上影响了道路交通噪声烦恼的水平。结果表明，在给定的 Lden,most 下，DIF ≥ 10 dB 亚组的道路交通噪声烦恼评分显著低于 DIF < 10 dB 亚组。此外，结果表明 Lden,least 的影响独立于 Lden,most。以 Lden,most 中等效变化表示的效应大小估计值，对于两个亚组之间的差异（DIF ≥ 10 dB 和 DIF < 10 dB）和约 10 dB 的 Lden,least 变化，均约为 5 dB。
