摘要
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。
he hearing of 369 soldiers in artillery was measured before exposure to cannon noise and after 2 and 3years service,The results showed that the high-frequency hearing loss rate for artillerist and non-artillerist was 28.3%and 24.6%respectively after 2 years service and、was 36.2%and 31.3%after 3 years service.The increased rate of hearing loss from first year to second year for artillerist and non-artillerist was 13.2%and 10.1% respectively and was 10.2%and 8.3%from secotid year to third year.The hearing loss rate of speech freqtieiicy was very low in both artillerist and non-artillerist.The results suggest that three years serviee in artillery at peace time can cause rather severe high-frequeney hearing loss, but no significant speech frequancy hearing loss.
