CONCLUSION
The results indicate that susceptibility to impulse noise differs in the three species.
OBJECTIVE
To test the hypothesis that there is different susceptibility to impulse noise trauma in three species: the guinea pig, rat and mouse.
MATERIALS AND METHODS
Three groups of animals were exposed to the same impulse noise and the effect on cochlear pathology was examined using auditory brainstem response thresholds.
RESULTS
It was found that the rat and mouse are more sensitive to impulse noise than the guinea pig.
结论
结果表明这三个物种对脉冲噪声的易感性不同。
目的
检验豚鼠、大鼠和小鼠这三个物种对脉冲噪声损伤存在不同易感性这一假设。
材料与方法
三组动物暴露于相同的脉冲噪声下，并使用听性脑干反应阈值检查对耳蜗病理的影响。
结果
发现大鼠和小鼠比豚鼠对脉冲噪声更敏感。
