The  study  assessed  the  effect  of  different  reflex  eliciting signals  and  the  ear  and  gender  effect on  contralateral  suppression  of  acoustic  reflexes.  A  clinical observational design was used to achieve the objective. 30 normal hearing subjects between age group of 17-30 years were randomly selected. A comparison between baseline acoustic reflex threshold and amplitude (at 10 dB SL) with the presence and absence of 40 dB SL white noise in the contralateral ear  was  recorded.  The  results  of  the  study  showed  that  there  was  suppression  of  acoustic  reflex threshold and  reflex  amplitude  for 500Hz, 1000 Hz, and 2000 Hz, low band  noise, high band  noise, broad  band  noise  and  clicks.  However,  there  was  no  significant  difference  in  the  amount  of suppression  of  acoustic  reflex  threshold  and  reflex  amplitude  across  stimuli,  gender  and  across  left and right ears. The result of the study shows that there is no effect of different stimuli on contralateral suppression of acoustic reflexes. In addition, there was no ear effect and gender effect on contralateral suppression  of  acoustic  reflexes.  Further  studies  with  all  the  stimuli  on  hearing  impaired  population are essential to know whether the method can be used for a larger clinical population.   aContralateral  Suppression  of  Acoustic  Reflex  Threshold,  Contralateral  Suppression  of Acoustic Reflex Amplitude, Stimulus effect, Ear Effect, Gender Effect, Medial efferent system.  aAkriti Kumar  aRevathi, R    aShezeen Abdul Gafoor   aInternational Journal of Health Sciences and Research  uhttps://www.ijhsr.org/IJHSR_Vol.6_Issue.1_Jan2016/65.pdf
