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。该研究以河南省森林公园中主要的 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∼2 kHz、2∼3 kHz、4∼5 kHz 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∼1 kHz 和 6∼7 kHz 的自然声常给人带来负面的影响。该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。

Abstract: 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 1–2 kHz, 2–3 kHz
and 4–5 kHz have a significant effect on increasing pleasure, reducing fatigue, and relaxing mood. However,
natural sounds at frequencies of 0.01–1 kHz and 6–7 kHz 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.
