目的:根据美国国家职业安全与健康研究所(NIOSH)提出的指南,测量泡菜球场上的噪声暴露并评估噪声引起的听力损失(NIHL)的风险。
方法:观察性研究测量里士满多个休闲泡菜球场的噪声水平,VA区域,记录LAeq,LASmax,在球场边和泡菜球场的等候区发言。在配备iMM-6校准测量麦克风(相当于IEC61672-1II类)的iPhone13上使用NIOSHSLM应用程序完成测量,该麦克风使用ND-9声级校准器(IEC942I类)进行校准。
结果:在法院附近的等候区记录的平均声级,以LAeq为单位测量,LASmax,还有LCspeak,分别为69.1dBA,92.0dBA,和112.1dBC,分别,虽然场边测量值是69.7dBA,92.2dBA,和115.6DBC,分别。这些测量在NIOSH和OSHA建议范围内。
结论:数据表明,根据NIOSH指南,随机抽样的泡菜球场的噪音水平不会增加参与者或旁观者的NIHL风险。然而,长时间的噪声暴露和环境噪声污染可能会对健康产生其他影响,需要进一步调查。

OBJECTIVE: To measure noise exposure present on pickleball courts and assess the risk of noise-induced hearing loss (NIHL) per guidelines put forward by the National Institute of Occupational Safety and Health (NIOSH).
METHODS: Observational study measuring noise levels at multiple recreational pickleball courts in the Richmond, VA area, documenting LAeq, LASmax, and LCpeak at courtside and waiting areas of pickleball courts. Measurements were completed using the NIOSH SLM application on an iPhone 13 with iMM-6 Calibrated Measurement Microphone (equivalent to IEC 61672-1 Class II) that was calibrated using ND-9 Sound Level Calibrator (IEC942 Class I).
RESULTS: Average sound levels recorded at waiting areas adjacent to the courts, measured in LAeq, LASmax, and LCpeak, were 69.1 dBA, 92.0 dBA, and 112.1 dBC, respectively, while courtside measurements were 69.7 dBA, 92.2 dBA, and 115.6 dBC, respectively. These measurements were within NIOSH and OSHA recommendations.
CONCLUSIONS: The data demonstrates that randomly sampled pickleball courts have noise levels that do not increase risk for NIHL for participants or bystanders alike based on NIOSH guidelines. However, prolonged noise exposure and ambient noise pollution may have other health implications and warrant further investigations.
METHODS: Level 2.
