Vestibular Evoked Myogenic Potentials (VEMPs) are very widely used in diagnosis of the vestibular disorder. Since VEMPs is are
under the influence of many variables, their clinical usefulness clinical usefulness has been controversially criticized. The aim of this
study was to increase the reliability of test results by adjusting configurations. Here, thirty seven ears of healthy adults who do not
have ontological problems were stimulated by different traits of sound, such as click and 500 Hz tone burst. Results were obtained by
three times of repeated incubation and comparison of the latency p1, n1, and amplitude of each wave, was also analyzed. As a result
of the test, the 500 Hz tone burst generated more stable and clearer waveforms than click; the most tests were repeated, the clearer
results were.. Filtering range of the low-frequency region to change the latency was significantly delayed than high-frequency region
even if sound stimulations are differenced. The results indicated that VEMPs can serve and effective tool in diagnosing the cause of
dizziness in the vestibular system. However, the control of test settings and surrounding environments are crucial for accurate and
reliable results of VEMPs. Further research is needed to establish VEMP testing processing
