峰度对非稳态噪声所致职业性听力损失的作用阈值
Threshold of kurtosis on occupational hearing loss associated with non-steady noise
摘要
Abstract
[Background]Kurtosis reflecting noise's temporal structure is an effective metric for evaluating noise-induced hearing loss(NIHL),and its threshold is still unclear. [Objective]To explore the energy range of kurtosis and the threshold of NIHL induced by kurtosis in this energy range [Methods]Using cross-sectional design,4 631 noise-exposed workers in manufacturing industry were selected.The hearing loss and noise exposure data of each worker were collected.Logistic regression model was used to establish the dose-response relationship between noise exposure and hearing loss and estimate the range of energy effects.Restricted cubic spline model was utilized to analyze the dose-response rela-tionship curves of kurtosis to noise-induced hearing loss(NIHI)and high-frequency noise-induced hearing loss(HFNIHL)under different 8 h equivalent sound levels(LEX,8h),as well as to estimate the kurtosis effect threshold. [Results]The logistic regression model analysis showed that the prevalence of NIHI and HFNIHL increased significantly with increase of LEX,8h for steady noise;when LEX8h of non-steady noise was 80-100 dB(A),the risk of hearing loss increased with an increase in kurtosis(P＜0.05).The restricted cubic spline model showed that when LEX,8h of non-steady noise was 0-80 dB(A)or＞100 dB(A),there was no sig-nificant relationship between kurtosis and NIHI or HFNIHL.When LEX,8h was 80-100 dB(A),there was a significant nonlinear dose-response relationship between kurtosis and NIHL or HFNIHL(P＜0.001),and kurtosis＞28.08 exerted effect in elevating NIHI or HFNIHL. [Conclusion]The effect threshold of kurtosis on NIHL is 28.08 when non-steady noise levels are in the range of 80-100 dB(A).The effect threshold of kurtosis needs further verification.关键词
