To elucidate mechanisms of dynamic evaluation for auditory environment in human brain, we investigated the relationship between temporal variation of physical factors of sound, psychological response, and physiological response (auditory evoked magnetic responses). To clarify the effects of variation of sound pressure level (SPL) on the auditory evoked response, we examined responses approximately 100 ms after an SPL change (the N1m'). The results revealed that N1m' amplitude increased with greater SPL changes. The pattern of amplitude change may reflect a difference in activation in the auditory nerve and/or primary auditory cortex. To clarify the effects of physical factors of sound on psychological annoyance, we examined relationship between physical factors and annoyance to sounds in train cars or stations and produced by air conditioning. The results indicated that annoyance can be predicted by SPL, fundamental frequency, strength of fundamental frequency, and spectral centroid.

为了阐明人脑听觉环境的动态评估机制，我们研究了声音物理因素的时间变化、心理反应和生理反应（听觉诱发磁反应）之间的关系。为了阐明声压级 (SPL) 变化对听觉诱发反应的影响，我们检查了 SPL 变化后大约 100 毫秒的响应（N1m'）。结果表明，N1m' 幅度随着声压级变化的增加而增加。幅度变化的模式可以反映听觉神经和/或初级听觉皮层的激活差异。为了阐明声音的物理因素对心理烦恼的影响，我们研究了物理因素与火车车厢或车站以及空调产生的声音的烦恼之间的关系。结果表明，可以通过声压级、基频、基频强度和频谱质心来预测烦恼度。
