峰度在评估复杂噪声所引起听力损失中的应用

摘要

A number of animal experiments and epidemiologic studies in humans have demonstrated that current in-ternational standards for noise exposure may underestimate hearing trauma by complex noise. While energy is a necessary metric, it is not sufficient to evaluate hearing hazards from complex noise exposure. The characteristic of complex noise is also an important factor in evaluating complex noise-induced hearing loss (NIHL). In this paper, the studies on using kurto-sis as a metric for complex NIHL evaluation in both animal and human models are introduced. The further research direc-tion and application prospect of kurtosis are discussed.%大量的动物实验和职业流行病学研究表明，目前的国际噪声暴露标准低估了复杂噪声对听力的危害程度，虽然能量是必要的评估参量但并不充分，复杂噪声本身的特性也至关重要。本文通过动物实验的结果，介绍峰度作为噪声能量的辅助参量，在评估复杂噪声所致听力损失的有效性，进而阐述如何从动物实验的结果推广到实际应用的思路，并用实例加以验证，对峰度参量研究的方向和应用前景进行了讨论。
