摘要

目的:在世界各地的调查中,幼儿园的噪音暴露被认为是学前教师的主要压力之一。与听力相关的症状以及生理应激反应经常被提及。因此,本研究的目的是调查噪音是否对幼儿教师的心血管活动有影响。方法:这项研究在维也纳的九所私立幼儿园进行。在23名幼儿教师的教室里进行了固定噪声记录,并为参与者配备了24小时心电图。提供了关于噪音相关压力、幸福感、压力感知、倦怠风险、噪音烦恼和噪音敏感性的问卷。对数据进行描述性描述,并对重复测量进行相关性和单因素方差分析(ANOVA)。结果:前四小时教室的平均声压水平为LAeq 74.7 dB(A)(标准差[SD] = 1.74)。心率和声压水平之间存在显著相关性(LAeq,4 h) 已找到,r = 0.40,P = 0.04(单尾)。噪声敏感度和噪声烦恼度没有影响。随着声压级[≤65 dB(A),66-75 dB(A,76-85 dB(A]]的增加,心率显著增加,心率变异性显著降低。研究还发现,随着工作时间的延长和年龄的增长,容忍噪音变得更加困难。结论:教室噪声水平对幼儿教师心血管活动有影响,可作为压力的指标。建议采取措施减少幼儿园的噪音。

Noise in Preschools and its Psychological and Cardiovascular Effect on Preschool Teachers.

Purpose: Noise exposure in preschools is cited as one of the main stresses by preschool teachers in surveys worldwide. Hearing-related symptoms as well as physiological stress reactions are often mentioned in this context. Therefore, the aim of the study was to investigate whether the noise has an impact on the cardiovascular activity of the preschool teachers.

Methods: The study took place in nine private preschools in Vienna. In the classrooms of 23 preschool teachers stationary noise recordings were conducted and the participants were equipped with 24-hour electrocardiograms (ECGs). Questionnaires on noise-related stress, well-being, stress perception, burnout risk, noise annoyance, and noise sensitivity were provided. Data were described descriptively and correlations and one-way analyses of variance (ANOVAs) with repeated measures were performed.

Results: The average sound pressure level in the classrooms during the first four hours was LAeq 74.7 dB(A) (standard deviation [SD] = 1.74). A significant correlation between heart rate and sound pressure level (LAeq,4 h) was found, r = 0.40, P = 0.04 (one-tailed). Noise sensitivity and noise annoyance showed no effect. With increasing sound level classes [≤65 dB(A), 66-75 dB(A), 76-85 dB(A)], the heart rate increased significantly, and the heart rate variability decreased significantly. It was also found that tolerating noise becomes more difficult with increasing length of employment and increasing age.

Conclusion: The noise level in classrooms showed an impact on the cardiovascular activity of preschool teachers, which can be considered as an indicator of stress. Measures to reduce noise in preschools are recommended.

期刊介绍: Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
