Abstract

This paper aims to investigate the temporal development of heartbeat intervals in a transition of different sound stimuli. In the listening experiment, two minutes relaxing musical piece and white noise were employed as the different sound stimuli, and the sound stimuli were played twice alternately after five minutes rest. After the exposure of the sound stimuli, a questionnaire asked the subjects relaxation feeling for rest, noise and music sections, respectively. Psychological result showed that music section induced the highest relaxation feeling and noise section induced the lowest relaxation feelings. Average of heartbeat intervals in music section was larger than that in noise section significantly (P≪0.05). Furthermore, after the transition of sound stimuli, it took about 30-s to change heartbeat interval from previous section. These results support the previous findings that investigated the effects of sound stimuli on heartbeat and will contribute to develop musical system reflecting a user's KANSEI information automatically.

声音刺激诱发不同放松感觉时心跳间隔的时间发展

本文旨在研究不同声音刺激下心跳间隔的时间发展。听力实验采用两分钟放松音乐和白噪声作为不同的声音刺激，休息5分钟后交替播放两种声音刺激。在声音刺激暴露后，问卷分别询问受试者对休息、噪音和音乐部分的放松感受。心理结果显示，音乐组的放松感最高，噪音组的放松感最低。音乐组心跳间隔的平均值明显大于噪声组(P≪0.05)。此外，在声音刺激转换后，心跳间隔与上一节相比大约需要30s。这些结果支持了先前研究声音刺激对心跳影响的发现，并将有助于开发自动反映用户感性信息的音乐系统。
