OBJECTIVE
To investigate effects of recreational noise exposure on olivocochlear efferent function.
METHODS
efferent suppression of DPOAEs and acoustic reflexes were tested in 32 young personal listening device users with normal hearing and compared with that of healthy, non-noise-exposed young adults.
RESULTS
The results showed that the efferent suppression of DPOAEs was mainly at low frequencies (0.75 and 1.0 kHz) in both groups and the efferent suppression of DPOAEs and acoustic reflexes in the noise exposure group was slightly lower than that in the control group, with no significant differences.
CONCLUSIONS
Our results revealed that there were no differences in DPOAE changes or medial olivocochlear bundle function between normal-hearing subjects exposed to recreational noise and controls and suggest that recreational noise has different effects on olivocochlear efferent reflex strength compared with occupational noise exposure.
目的
探讨娱乐性噪声暴露对橄榄耳蜗传出功能的影响。
方法
测试了 32 名听力正常的年轻个人听力设备使用者的 DPOAE 传出抑制和声反射，并与健康、无噪声暴露的年轻成年人进行了比较。
结果
结果表明，两组的 DPOAE 传出抑制主要在低频（0.75 和 1.0 kHz），噪声暴露组的 DPOAE 和声反射的传出抑制略低于对照组，但无统计学差异。
结论
我们的结果表明，暴露于娱乐性噪声的正常听力受试者与对照组之间的 DPOAE 变化或内侧橄榄耳蜗束功能没有差异，这表明与职业噪声暴露相比，娱乐性噪声对橄榄耳蜗传出反射强度有不同的影响。
