    Objective: The study aimed to examine the effect of the stimulus phase of air-conducted sound on ocular vestibular evoked myogenic potentials (oVEMPs). Methods: oVEMPs were recorded after air-conducted sounds (500 Hz, 4 ms duration), presented with initial condensation (positive), rarefaction (negative), and alternant polarities from 12 healthy subjects. Results: Most responses showed a bifid n10 peak separated by similar to 1.9 ms. The most prominent sub-peak after condensation was shorter than the most prominent sub-peak after rarefaction
