职业性噪声性听力损失(NIHL)很普遍，但缺乏预防干预措施有效性的证据。对一项新技术的有效性进行了分析，该技术允许工作人员每天监测耳边的噪音暴露。由于听力损失速度加快，一家铝冶炼厂听力保护项目的工作人员被招募。干预措施包括对耳部噪声暴露的日常监测和主管对暴露情况的定期反馈。测定干预前(2000~2004年)和干预后4年(2006~2009年)平均2、3、4 kHz高频听力的年变化率。2005年，在年龄、性别和高频听力阈值水平匹配的其他公司冶炼厂中，对78名干预对象和234名对照的年损失率进行了比较。每天监测噪声暴露的个体平均没有经历高频听力的进一步恶化(2、3和4 kHz时的平均听力变化率=-0.5分贝/年)。配对的对照组也表现出减速听力损失，两组之间的比率差异显著(p<；0.0001)。对一组与对照组相匹配的干预受试者的初始听力损失比率的分析显示出类似的趋势，但差异不具有统计学意义(p=0.06)。通过持续的行政反馈监测听力保护内的日常职业性噪声暴露，显然可以降低产业工人职业性NIHL的风险。对这些工人进行更长时间的随访将有助于确定干预效果的重要性。预防新生儿急性淋巴细胞性白血病的干预研究需要包括适当的对照组。
Occupational noise-induced hearing loss (NIHL) is prevalent, yet evidence on the effectiveness of preventive interventions is lacking. The effectiveness of a new technology allowing workers to monitor daily at-ear noise exposure was analysed. Workers in the hearing conservation program of an aluminium smelter were recruited because of accelerated rates of hearing loss. The intervention consisted of daily monitoring of at-ear noise exposure and regular feedback on exposures from supervisors. The annual rate of change in high frequency hearing average at 2, 3 and 4 KHz before intervention (2000–2004) and 4 years after intervention (2006–2009) was determined. Annual rates of loss were compared between 78 intervention subjects and 234 controls in other company smelters matched for age, gender and high frequency hearing threshold level in 2005. Individuals monitoring daily noise exposure experienced on average no further worsening of high frequency hearing (average rate of hearing change at 2, 3 and 4 KHz=–0.5 dB/year). Matched controls also showed decelerating hearing loss, the difference in rates between the two groups being significant (p<0.0001). Analysis of a subset of intervention subjects matched to controls for initial rate of hearing loss showed a similar trend but the difference was not statistically significant (p=0.06). Monitoring daily occupational noise exposure inside hearing protection with ongoing administrative feedback apparently reduces the risk of occupational NIHL in industrial workers. Longer follow-up of these workers will help determine the significance of the intervention effect. Intervention studies for the prevention of NIHL need to include appropriate control groups.
