{Abstract}: BACKGROUND: Acoustic reflex (AR) is a valuable clinical test for hearing diagnosis. Parameters of AR such as its amplitude and threshold have been commonly reported in research. Acoustic reflex latency (ARL) has not been widely studied and more research is warranted to determine its basic properties and clinical usefulness. The present study aimed to determine the influences of stimulation mode and stimulus frequency on ARL.
METHODS: In this study, 52 healthy young adults were enrolled (mean age = 23.2 ± 0.8 years, 61.8% were males). They underwent the standard AR testing and ARL values were computed. Both ipsilateral and contralateral recordings were made at 500, 1000, 2000 and 4000 Hz frequencies.
RESULTS: The ARL values obtained are consistent with the findings from the previous studies. Two-way analysis of variance (ANOVA) revealed that the ARL values were not statistically influenced by either stimulation mode (p = 0.061) or stimulus frequency (p = 0.598).
CONCLUSIONS: Among young adults, ARL does not appear to be influenced by stimulation mode and stimulus frequency. Further large scale research is warranted to support the present study's findings. The preliminary normative data for ARL obtained in this study can serve as the reference for future research involving this particular population.
