An experimental study was performed to compare the annoyances from civil-aircraft noise, military-aircraft noise, railway noise, and road-traffic noise. Two-way within-subjects designs were applied in this research. Fifty-two subjects, who were naive listeners, were given various stimuli with varying levels through a headphone in an anechoic chamber. Regardless of the frequency weighting network, even under the same average energy level, civil-aircraft noise was the most annoying, followed by military-aircraft noise, railway noise, and road-traffic noise. In particular, penalties in the time-averaged, A-weighted sound level (TAL) of about 8, 5, and 5 dB, respectively, were found in the civil-aircraft, military-aircraft, and railway noises. The reason could be clarified through the high-frequency component and the variability in the level. When people were exposed to sounds with the same maximum A-weighted level, a railway bonus of about 3 dB was found. However, transportation noise has been evaluated by the time-averaged A-weighted level in most countries. Therefore, in the present situation, the railway bonus is not acceptable for railway vehicles with diesel-electric engines.
进行了一项实验研究，比较了民用飞机噪声、军用飞机噪声、铁路噪声和道路交通噪声的烦恼程度。本研究采用了双向被试内设计。52 名天真的听众在消声室内通过耳机接受各种不同水平的不同刺激。无论频率加权网络如何，即使在相同的平均能量水平下，民用飞机噪声也是最令人烦恼的，其次是军用飞机噪声、铁路噪声和道路交通噪声。特别是，在时间平均 A 加权声级（TAL）中，民用飞机、军用飞机和铁路噪声分别有大约 8、5 和 5 dB 的惩罚。通过高频分量和水平的可变性可以解释原因。当人们暴露在具有相同最大 A 加权水平的声音中时，发现铁路噪声有大约 3 dB 的附加噪声。然而，在大多数国家，交通噪声都是通过时间平均 A 加权水平来评估的。因此，在目前的情况下，对于使用柴油-电力发动机的铁路车辆来说，铁路噪声附加量是不可接受的。
