Acoustic Impedance in the Human Ear Canal

Scandinavian Audiology, 1994
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.
