There is no unified standard for measuring workplace non-Gaussian noise (known as complex noise) exposure. This study aimed to develop a draft guideline for measuring workplace non-Gaussian complex noise exposure based on noise temporal structure adjustment.
Noise exposure level, e.g., the A-weighted sound pressure level normalized to a nominal 8-h working day (L), was adjusted using the temporal structure (expressed by kurtosis) of noise. Noise waveform analysis or the instrument's direct reading was used.
The framework of the draft guideline included measurement metrics, the protocol using kurtosis to adjust L, technical requirements for measuring instruments, measurement steps, data analysis, and measurement recording.
The draft guideline could provide a basis for accurately measuring workers' exposure to non-Gaussian noise.
目前尚无用于测量工作场所非高斯噪声（亦称复合噪声）暴露的统一标准。本研究旨在制定基于噪声时间结构调整的工作场所非高斯复合噪声暴露测量准则草案。
采用噪声时间结构（用峭度表示）对噪声暴露水平（如归一化为名义 8 小时工作日的 A 加权声压级（L））进行调整。可采用噪声波形分析或仪器直接读数的方式。
准则草案框架包括测量指标、使用峭度调整 L 的方案、测量仪器的技术要求、测量步骤、数据分析和测量记录。
准则草案可为准确测量工人非高斯噪声暴露提供依据。
