This study aimed to determine the optimal bandpass filter (BPF) setting for acoustic stimuli in recording the ocular vestibular-evoked myogenic potential (oVEMP). Twelve healthy volunteers underwent oVEMP tests using acoustic stimuli with various high-pass filters (1, 10 and 100. Hz) and low-pass filters (500, 1000 and 2000. Hz). Initially, various effects of high-pass filter on the oVEMPs were examined under Conditions A (BPF of 1-1000. Hz), B (BPF of 10-1000. Hz) and C (BPF of 100-1000. Hz). Of these conditions, Condition A showed 100% response rate and had larger n. I-p. I amplitude than Conditions B and C. Thus, Condition A was selected for subsequent analysis of the various effects of low-pass filter on the oVEMPs. However, Condition A (BPF of 1-1000. Hz) did not significantly differ from Conditions D (BPF of 1-500. Hz) and E (BPF of 1-2000. Hz) in terms of the latencies and amplitudes of oVEMPs. Condition A thus is supposed to be the optimal recording condition for oVEMPs. In conclusion, the optimal BPF setting for acoustic stimuli in recording oVEMPs is suggested to be between 1 and 1000.
