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。
