Abstract

This study was designed to investigate the relationship between sound level and autonomic arousal using acoustic signals similar in level and acoustic properties to common sounds in the built environment. Thirty-three young adults were exposed to background sound modeled on ventilation equipment noise presented at levels ranging from 35 to 75 dBA sound pressure level (SPL) in 2 min blocks while they sat and read quietly. Autonomic arousal was measured in terms of skin conductance level. Results suggest that there is a direct relationship between sound level and arousal, even at these realistic levels. However, the effect of habituation appears to be more important overall.

背景噪音对自律神经唤醒(皮肤电导水平)的影响。
本研究旨在利用与建筑环境中常见声音的声级和声学特性相似的声学信号,研究声级与自律神经唤醒之间的关系。研究人员以通风设备噪音为模型,让 33 名年轻人在安静地坐着阅读时暴露在声压级 (SPL) 从 35 dBA 到 75 dBA 不等的背景声中,时间为 2 分钟。根据皮肤电导水平测量自主神经唤醒。结果表明,即使在这些真实的声压级下,声压级与唤醒之间也存在直接关系。不过,总体看来,习惯化的影响更为重要。
