【摘要】：目的进一步探索民航机场工作环境噪声对机场工作人员听觉功能的影响。方法对国内某民航机场的34名工作人员进行了畸变产物耳声发射(distortion product otoacoustic emissions,DPOAE)检查,并比较分析了外场组与室内组、左耳与右耳以及各工龄组间DPOAE信噪比(signal noise ratio,SNR)的幅值和检出率的差异。结果室内组和外场组各个频率SNR的检出率均小于100%,室内组SNR的幅值和检出率在多个频率点显著高于外场组(P0.05),以3000 Hz和4000 Hz差异尤为显著(P0.01);工龄15～29年组和30年以上组SNR的幅值和检出率在多个频率点显著高于0～14年组(P0.05),而工龄15～29年组和30年以上组间未见显著性差异;左右耳之间SNR的幅值和检出率未见显著性差异。结论机场噪声对机场工作人员的听觉功能造成了损害,由于外场工作人员噪声暴露强度高于室内工作人员,所以其听觉功能损害程度更加严重;接触噪声时间越长损害越严重。
[Abstract]:Objective to explore the effect of noise in civil aviation airport working environment on the auditory function of airport staff. Methods 34 workers at a civil aviation airport in China were examined by distortion product otoacoustic emission (distortion product otoacoustic missions) DPOAE, and the field group and the indoor group were compared and analyzed. The amplitude and detection rate of DPOAE signal-to-noise ratio (SNR) and signal noise signal (SNR) in left ear, right ear and different age groups. Results the detection rate of SNR in indoor group and outfield group was less than 100. The amplitude and detection rate of SNR in indoor group was significantly higher than that in field group at many frequency points, especially in 3000 Hz and 4000 Hz group, and the working period was 15 ~ 29 years and more than 30 years. The amplitude and detection rate of SNR were significantly higher in the group of 0 ~ 14 years than in the group of 0 ~ 14 years, but there was no significant difference between the group of 15 ~ 29 years and the group of more than 30 years. There was no significant difference in the amplitude and detection rate of SNR between left and right ears. Conclusion Airport noise has damaged the auditory function of airport staff. Because the noise exposure intensity of field staff is higher than that of indoor staff, the degree of noise damage is more serious, and the longer the exposure to noise is, the more serious the damage is.
