Abstract

Abstract Soundscapes affect the health and quality of life of humans. Noisy soundscapes have a negative impact on humans causing annoyance, sleep disturbance and cardiovascular issues. This paper analyses the change in heart rate variability (HRV) due to exposure of different soundscape stimuli. A total of 40 soundscape stimuli were collected from New Delhi India, which were grouped into three clusters, ‘Loud’, ‘Active’ and ‘Silent’, based on psychoacoustic indicators. Listening experiments were conducted with 25 healthy participants, during which electro-cardiography responses were collected as response variable. HRV analysis was performed to analyse the change in time domain (Heart rate, SDNN, NN50, pNN50) and frequency domain (VLF, LF, HF, LF/LF ratio) parameters. A significant change in heart rate is observed with an increase in loudness of stimuli. The change in HRV is analysed by considering noise sensitivity level of participants. A significant decrease in SDNN is noted for participants with high noise sensitivity. Frequency domain parameters of HRV did not exhibit a significant change due to noise exposure. A significant decrease in SDNN suggests imbalanced autonomic nervous system activation, which increases the risk of cardiovascular diseases, particularly for people with high noise sensitivity.

评价不同声景引起的心率变异性变化

声景影响着人类的健康和生活质量。嘈杂的声音环境对人类有负面影响，会引起烦恼、睡眠障碍和心血管问题。本文分析了不同声景刺激对心率变异性的影响。从印度新德里收集了总共40个声景刺激，根据心理声学指标将其分为“大声”、“活跃”和“沉默”三组。对25名健康受试者进行听力实验，收集心电图反应作为反应变量。HRV分析时域(心率、SDNN、NN50、pNN50)和频域(VLF、LF、HF、LF/LF比值)参数的变化。随着刺激音量的增加，可以观察到心率的显著变化。考虑被试的噪声敏感程度，分析HRV的变化。对于高噪声敏感性的参与者，SDNN显著降低。HRV的频域参数没有表现出明显的变化，因为噪声暴露。SDNN的显著下降表明自主神经系统激活不平衡，这增加了心血管疾病的风险，特别是对高噪音敏感性的人。

期刊介绍： Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
