Abstract

Introduction Caffeine is consumed everyday in a variety of ways by a large population around the world, including coffee, tea, and soft drinks. Therefore, there is a significant need to explore the effects of caffeine on human auditory system. The present study aimed to investigate the effect of caffeine on cochlea using distortion product otoacoustic emission (DPOAE).

Materials and Methods Thirty-three young adults were recruited for the study. The effect of caffeine on cochlea was assessed using DPOAE at frequencies between 1 to 10 kHz before and after caffeine consumption.

Results The signal to noise ratio of DPOAE was compared before and after coffee intake, which revealed no significant differences.

Conclusion The current study results suggest that caffeine has no effect on cochlear functioning.

Keywords
