【摘要】：目的建立听力信息监控系统,应用该系统获得某军单位1、单位2、单位3应招入伍士兵听力信息基线数据,并对基线数据进行分析。方法评估及调研军事噪声听力检测入网设备及系统软硬件设备,建立军事噪声动态监控系统并与听力检测设备形成移动式局域网络,为不同营区496名即将从事高噪声军事作业的新入伍士兵进行常规体格检查和听力检查。统计学调查数据用PASW statistics 18进行分析,整体均数差异性比较采用非参数检验,P0.05示差异有统计学意义。结果完成动态听力监控系统的建设,应用该系统分3天为496名男士兵完成听力学检测,以excel表形式导出全部听力数据并分析。结果示:检测士兵年龄范围17-25岁,平均年龄19岁,中耳鼓室图异常5人,根据GJB 2121-94分级,496名士兵中479人听力正常,17人存在听力损失;按照全频平均听阈分析,有73耳存在听力损失,其中轻度68耳,中度5耳。将496人各频率听力水平进行差异性比较,P0.05,示各频率听力损失水平整体均值有显著统计学差异,组间多重两两比较P0.01,示3kHz和6kHz分别与其余频率听力水平有显著统计学差异。结论应用听力损失动态监控系统获得军事噪声作业人员听力信息数据方便快捷;基线数据提示:部分士兵在军事噪声暴露前已存在不同程度的听力损失,获得精准的军事噪声听力损失数据,是进一步监控官兵听力损失的关键环节。
[Abstract]:Objective to establish a hearing information monitoring system and use the system to obtain the baseline data of 1 unit 2 units and 3 units of enlisted soldiers and analyze the baseline data. Methods to evaluate and investigate the military noise hearing detection network equipment and the system hardware and software equipment, to establish the military noise dynamic monitoring system and to form a mobile local area network with the hearing detection equipment. Routine physical examination and hearing examination were performed for 496 newly recruited soldiers who were about to engage in high-noise military operations in different camp areas. The statistical survey data were analyzed by PASW statistics 18, the difference of the overall mean was compared by non-parametric test, P0.05 showed that the difference was statistically significant. Results the construction of dynamic hearing monitoring system was completed. The hearing test was completed for 496 male soldiers in three days. All the hearing data were derived and analyzed by excel table. The results showed that the age range of the soldiers was 17-25 years, the average age was 19 years, and the tympanogram of the middle ear was abnormal in 5 cases. According to GJB 2121-94 classification, 479 of the 496 soldiers had normal hearing and 17 had hearing loss. According to the full-frequency average hearing threshold analysis, 73 ears had hearing loss, including mild 68 ears and moderate 5 ears. The differences of hearing levels among 496 people at different frequencies were compared (P0.05). The results showed that there was significant statistical difference in the overall mean of hearing loss levels among different frequencies, and there was a significant difference between the two groups (P0.01). The results showed that 3kHz and 6kHz were significantly different from the other frequencies. Conclusion it is convenient and quick to obtain the hearing information data of military noise workers by using the dynamic monitoring system of hearing loss. Baseline data suggest that some soldiers have different degrees of hearing loss before exposure to military noise. Obtaining accurate hearing loss data of military noise is the key link to further monitor the hearing loss of officers and soldiers.
