Recently, it has been suggested that the annoyance of residents at a given aircraft noise exposure level increases over the years. The objective of the present study was to verify the hypothesized trend and to identify its possible causes. To this end, the large database used to establish earlier exposure-response relationships on aircraft noise was updated with original data from several recent surveys, yielding a database with data from 34 separate airports. Multilevel grouped regression was used to determine the annoyance response per airport, after which meta-regression was used to investigate whether study characteristics could explain the heterogeneity in annoyance response between airports. A significant increase over the years was observed in annoyance at a given level of aircraft noise exposure. Furthermore, the type of annoyance scale, the type of contact, and the response percentage were found to be sources of heterogeneity. Of these, only the scale factor could statistically account for the trend, although other findings rule it out as a satisfactory explanation. No evidence was found for increased self-reported noise sensitivity. The results are of importance to the applicability of current exposure-annoyance relationships for aircraft noise and provide a basis for decisions on whether these need to be updated.
最近有人提出，居民对特定飞机噪声暴露水平的烦恼会随着时间的推移而增加。本研究的目的是验证假设的趋势，并确定其可能的原因。为此，利用最新的几次调查的原始数据更新了用于建立早期飞机噪声暴露-反应关系的大型数据库，从而形成了一个包含 34 个单独机场数据的数据库。采用多层次分组回归确定每个机场的烦恼反应，然后进行荟萃回归，以研究研究特征是否可以解释机场之间烦恼反应的异质性。在给定的飞机噪声暴露水平下，烦恼程度观察到了显著的逐年增加。此外，烦恼量表的类型、接触类型和反应百分比被发现是烦恼反应异质性的来源。其中，只有量表因素可以从统计学上解释这一趋势，尽管其他发现排除了它作为一种令人满意的解释。没有证据表明自我报告的噪声敏感性增加。这些结果对当前飞机噪声暴露-烦恼关系的适用性具有重要意义，并为是否需要更新这些关系提供了依据。
