空中交通量的增加意味着人们暴露在更多的飞机噪音中，尽管现代飞机比以前更安静。为了从声音设计的角度设计更好的飞机，有必要了解人们如何从心理上感知飞机噪声，以及哪些物理参数对心理评估有影响。我们通过声音的三个主要感知维度来评估对飞机噪声的心理反应：烦恼作为评价，响度作为潜力，音高作为活动。心理反应和物理参数之间的关系被确定。结果表明，声级、声级的时间变化和频谱含量是影响主观烦恼的重要因素。声级和频谱内容也显著影响主观响度。对于主观音高，声级的时间变化和频谱质心是显著的影响因素。
Increase in air traffic means that people are exposed to more aircraft noise although modern aircraft are quieter than before. To design better aircraft from a sound design point of view, it is necessary to understand how people perceive aircraft noise psychologically and which physical parameters are influential for psychological evaluation. We evaluated psychological responses to aircraft noise by three major perceptual dimensions of sound: annoyance asEvaluation, loudness asPotency, and pitch asActivity. The relationship between psychological responses and physical parameters was determined. Results indicated that sound level, the temporal variation of sound level, and spectral content are significant factors influencing subjective annoyance. Sound level and spectral content also significantly influence subjective loudness. As for subjective pitch, the temporal variation of the sound level and spectral centroid are significantly influential factors.
