normal hearing

I don't think that superhuman hearing is likely, or even a good idea, because the normal human ear is already awesomely sensitive.

我认为超人般的耳朵是不可能的，甚至是不好的主意，因为正常人的耳朵已经非常敏感。

Results The 2f 1 f 2 DPOAE amplitudes in all pilots, including pilots with normal audiometric hearing and with hearing loss, were significantly lower than those of control group.

结果飞行员组DPOAE幅值与健康青年组相比明显降低，特别是飞行员纯音听阈正常组DPOAE幅值较健康青年组也明显降低。

They then travel the nervous system directly to the brain ( bypassing normal hearing mechanisms ).

它们能直接传递到神经系统 ( 扰过普通的听力器官 ).

The relationship of the pure tone audiogram and DPOAE audiogram were tested. Results The detected DPOAE rate and DPOAE amplitudes in normal hearing group were significantly higher than that in other three groups ( P < 0.05).

结果纯音听阈正常组的DPOAE检出率及DPOAE振幅明显高于低频听力下降组、高频听力下降组及全频听力下降组（P＜0.01或0.05）；

TEOAE energy distribution takes the average energy of the normal hearing persons as 0 dB, and 5% percentage at single side as the 95% normal value range. TEOAE energy distribution represents the energy loss and is convenient for the comparison to the pure tone audiogram.

TEOAE能量分布图以正常人的平均能量作为0dB，以单侧5%位数作为95%正常值范围，它体现了能量的损失情况，便于与纯音测听的结果相比较。

Completely normal hearing is still uncommon.

但要拥有完全正常的听力,仍可遇不可求.
