The aim of this exploratory study was to examine whether the kurtosis metric can contribute to investigations of the effects of combined exposure to noise and solvents on human hearing thresholds. Twenty factory workers exposed to noise and solvents along with 20 workers of similar age exposed only to noise in eastern China were investigated using pure-tone audiometry (1000-8000 Hz). Exposure histories and shift-long noise recording files were obtained for each participant. The data were used in the calculation of the cumulative noise exposure (CNE) and CNE adjusted by the kurtosis metric for each participant. Passive samplers were used to measure solvent concentrations for each worker exposed to solvents over the full work shift. Results showed an interaction between noise exposure and solvents for the hearing threshold at 6000 Hz. This effect was observed only when the CNE level was adjusted by the kurtosis metric.
本探索性研究旨在探讨峰态度量是否有助于研究噪声和溶剂联合暴露对人耳听阈的影响。在中国东部，20 名同时接触噪声和溶剂的工厂工人和 20 名仅接触噪声的年龄相似的工人接受了纯音测听（1000-8000Hz）检查。为每位参与者获取了接触史和轮班噪声记录文件。使用这些数据计算每位参与者的累积噪声暴露（CNE）和通过峰态度量调整的 CNE。对于每个接触溶剂的工人，使用被动采样器在整个工作班次内测量溶剂浓度。结果表明，噪声暴露和溶剂对 6000Hz 听力阈值存在交互作用。仅当 CNE 水平通过峰态度量调整时才会观察到这种影响。
