Abstract

For 13 normal-hearing test persons, the acoustic impedance about 6 mm inside the ear canal entrance has been measured in the frequency range 90-20,000 Hz by using standing wave measuring tubes connected to the ear canal via small ear adaptor tubes. The results show good reproducibility but large individual differences.

摘要

对于13名听力正常的测试者，通过使用经由小耳适配管连接到耳道的驻波测量管，在90 - 20000赫兹的频率范围内测量了耳道入口内约6毫米处的声阻抗。结果显示出良好的可重复性，但个体差异较大。
