1.在高速列车中，可能会出现由电机或波纹钢轨产生的音调分量。由于从文献（[1]、[2]、[3]）中众所周知，含有音调分量的环境或人工噪声比不含音调分量的噪声更令人讨厌，因此本研究评估减少此类音调分量的重要性。因此，在心理声学实验中合成和分析典型的声音，其目的如下：究竟有多少音调成分需要突出才能被感知？在有限的频带中，声能的增加或减少与心理声学感觉的音调有什么关系？这种音调对感知的音质有什么影响？
1. Introduction In high-speed trains, tonal components produced either by the motor or by corrugated rails may occur. As it is well-known from literature ([1], [2], [3]) that environmental or artificial noise containing tonal components is more annoying than noise without tonal components, the present investigation assesses the importance of reducing such tonal components. Therefore, typical sounds were synthesized and analyzed in psychoacoustic experiments with the following intentions: how much has a tonal component to stick out to be perceived at all? How are increases or decreases in sound energy in a limited frequency band related to the psychoacoustic sensation tonalness? What influence does this tonalness have on the perceived sound quality?
