本文对３６９名新入伍炮兵战士在第一年尚未经受火炮噪声暴露前、第二年及第三年作了听力追踪调查。结果表明，有高频听力损失者第二年占被检人数：炮手为２８．３％，非炮手为２４．６％，第三年分别为３６．２％和３１．３％；第一年到第二年高频听力损失的增加率炮手为１３．２％，非炮手为１０．１％，第二年到第三年高频听力损失的增加率分别为１０．２％和８．３％；炮手、非炮手语频听力损失的发生率都很低。提示在平时情况下，经三年炮兵服役可引起较高的高频听力损失，但对语频听力影响不大。
In this paper, 369 newly enlisted artillery soldiers made a hearing-follow-up survey before, during the second year and the third year after the first year had not been exposed by the artillery noise. The results showed that those with high-frequency hearing loss accounted for the second year of seized persons: 28.3% of gunners, 24.6% of non-gunners and 36.2% and 31.3% of the third year respectively. In the first year By the second year, the increase rate of high-frequency hearing loss was 13.2% for gunners and 10.1% for non-gunners. The increase rates of high-frequency hearing loss from the second year to the third year were 10.2% and 8.3% %; Gunners, non-gunners hearing loss frequency is very low. Tip Under normal circumstances, after three years of artillery service can cause higher high-frequency hearing loss, but little effect on the audio frequency hearing.
