为了研究飞机噪声事件之间的安静时间间隔对飞机噪声的总体负面印象的影响，进行了心理实验，其中安静时间间隔是不同的，并考虑到事件的数量和每个刺激的持续时间。对于相等的A加权等效连续声压级（LAeq）之间的刺激，有人发现，整体噪声下降的安静时间间隔比的刺激增加。研究还发现，通过调整安静时间间隔比率或刺激中包含的事件数量，整体噪声和LAeq之间的相关性得到改善，特别是当参与者注意瞬时噪声水平的变化时。这项研究表明，LAeq是一个很好的基础，用于评估飞机噪音的负面印象，但纠正安静的时间间隔和/或航班数量提高了LAeq和负面印象之间的相关性，在这种飞机噪音的情况。
In order to investigate the effect of the quiet-time interval between aircraft noise events on the overall negative impression of aircraft noise, psychological experiments were conducted in which the quiet-time interval was varied and the number of events and duration of each stimulus were taken into account. For equal A-weighted equivalent continuous sound pressure level (LAeq) among the stimuli, it was found that overall noisiness decreased as the quiet-time interval ratio of the stimulus was increased. It was also found that the correlation between overall noisiness and LAeq was improved by adjusting for the quiet-time interval ratio or the number of events included in the stimuli, especially when participants paid attention to changes in the instantaneous noise level. This study reveals that LAeq is a good basis for evaluating the negative impressions of aircraft noise, but that correcting for the quiet-time interval and/or number of flights improves the correlation between LAeq and the negative impression in such aircraft noise situations.
