【摘要】：目的探讨畸变产物耳声发射(DPOAE)在军事噪声致爆震性聋早期监测中的作用。方法将听力正常的炮兵某部男性官兵88例(176耳)随机分成两组,每组44例(88耳),实验组参加火炮实弹射击训练,对照组未参加火炮实弹射击训练。对照组及实验组训练前后进行纯音测听及DPOAE测试,对两组结果进行比较分析。结果实验组训练后80耳中耳传导功能无障碍,其中13耳纯音听阈示感音神经性听力损失,DPOAE检查亦异常;67耳纯音听阈正常,其中15耳DPOAE幅值在4kHz处降低。与训练前、对照组比较,实验组训练后2、4及8kHz纯音听阈升高(P0.05或P0.01),以4kHz处升高最为明显;实验组训练后2、3、4、6及8kHzDPOAE幅值降低(P0.05或P0.01),其中以4kHz处降低最为明显。结论畸变产物耳声发射在军事噪声致爆震性聋早期监测中有一定应用价值,可对其防护、诊断和治疗提供指导和帮助。
[Abstract]:Objective to investigate the role of distortion product otoacoustic emission (DPOAE) in early monitoring of explosive deafness caused by military noise. Methods 88 male officers and soldiers with normal hearing were randomly divided into two groups. In each group of 44 cases with 88 ears, the experimental group took part in the training of live artillery firing, while the control group did not take part in the training. The control group and the experimental group underwent pure tone audiometry and DPOAE test before and after training. Results the conduction function of 80 ears in the experimental group was unobstructed after training, and 13 ears showed sensorineural hearing loss and DPOAE examination showed that the pure tone hearing threshold was normal in 67 ears. The amplitude of DPOAE in 15 ears decreased at 4 kHz. Compared with the control group, the pure tone hearing threshold of the experimental group increased after training (P0.05 or P0.01), especially at 4 kHz. After training, the amplitudes of DPOAE in the experimental group were decreased by P0.05 or P0.01, especially at 4 kHz. Conclusion distortion product otoacoustic emission is valuable in early monitoring of explosive deafness caused by military noise, and can be protected against it. Provide guidance and assistance in diagnosis and treatment.
