The probe features an aluminium holder connected to a microphone and an earphone with two acoustic holes bored into the probe tip metal plane and covered with a plastic earplug. As a result, barreled tubing is not utilized. The frequency characteristic of earphone was within 5 dB between 150 Hz and 4 kHz. The frequency characteristic curve of the microphone varied within 10 dB from 150 Hz to 9 kHz. The probe has a total weight of only 13.5g. The holding system fits snugly and securely into external auditory canal allowing for EOAE examination in sitting position. It is also feasible for EOAE examination in a soundproof room for single-person use and in out-patient clinics.
