| 中文摘要: |
| 森林公园中的自然声对人的身心健康具有重要意义。频率是自然声重要的物理参数之一，关系到自然声的音高和音调。本研究以河南省森林公园中主要18种自然声作为样本，应用脑电仪器测定人脑的4大脑区16个通道的6种脑电波振幅变化情况，分析在不同频率自然声刺激下人的脑电生理反应。结果表明：不同频率的自然声对于人的感知、生理都具有重要的影响，在帮助人缓解压力、增加安全感、提升愉悦感存在差异；频率范围在1～2kHz、2～3kHz、4～5kHz的自然声，对于增加愉悦感、降低疲劳度和放松心情方面有显著的效果；而频率在0.01～1kHz和6～7kHz的自然声常给人带来负面的影响。本次研究揭示了不同频率的自然声对人的脑电生理影响差异，为森林公园声景规划设计和游客游览体验感提升给予数据支持。 |
| 英文摘要: |
| Natural sounds in forest parks are of great significance to human physical and mental health. Frequency, one of the critical physical parameters of natural sounds, is related to their tonal characteristics and timbre quality. This study took 18 major natural sounds in the forest parks of Henan Province as samples, using electroencephalography (EEG) to measure the changes in the amplitudes of six types of brainwaves in sixteen channels of the four major brain regions. It analyzed the human brain's physiological responses to the stimulation of natural sounds at different frequencies. The results showed that natural sounds of varying frequencies have vital effects on human perception and physiology, with differences in helping people to relieve stress, enhance the sense of security and pleasure. Natural sounds within frequency ranges of 1~2kHz, 2~3kHz and 4~5kHz have a significant effect on increasing pleasure, reducing fatigue, and relaxing mood. However, natural sounds at frequencies of 0.01~1kHz and 6~7kHz often bring negative impacts. This study revealed the differences in the effects of natural sounds of different frequencies on human brain physiology, providing data support for the soundscape planning and design as well as improving visitors' experience in forest parks. |
