Detailed neurological and audiological examinations and body-sway measurements with a stable platform were carried out on 60 subjects who had been exposed to high-energy intermittent noise from firearms and had various degrees of noise-induced hearing loss. The results were compared with those for 115 healthy controls. The exposed subjects showed significantly more body sway, estimated as movement of the centre of gravity in the horizontal plane, than the controls. This swaying correlated poorly with the recalled level of noise exposure, though subjects with more severe hearing loss (by audiometric deterioration of high-frequency sound, 4 kHz and 6 kHz) showed more sway than those with less severe hearing loss. Age was not significantly correlated with body sway among the controls but men seemed to sway more than women. These results suggest subclinical disturbance of the vestibular system among subjects with impulse-noise-induced hearing loss.
对60名曾暴露于枪支高能间歇性噪声并患有不同程度噪声性听力损失的受试者进行了详细的神经学和听力学检查，以及使用稳定平台进行的身体摆动测量。将结果与115名健康对照者的结果进行比较。与对照组相比，暴露组受试者在水平面内重心移动所估计的身体摆动明显更多。尽管听力损失更严重（通过4kHz和6kHz高频声音的听力测定恶化）的受试者比听力损失较轻的受试者摆动更多，但这种摆动与回忆的噪声暴露水平相关性较差。在对照组中，年龄与身体摆动无显著相关性，但男性似乎比女性摆动更多。这些结果表明，在患有脉冲噪声性听力损失的受试者中存在前庭系统的亚临床紊乱。
