AB  - This study aimed to evaluate the effect of impulse noise on otoacoustic emissions 
      (OAEs) while a passive non-linear earplug or an active level-dependent earmuff 
      was worn. Since none of the standardized attenuation measurement techniques, REAT 
      (real ear at threshold), ATF (acoustic test fixture), or MIRE (microphone in real 
      ear), is designed to test both types in real-wearing condition, OAEs, suitable 
      for detecting subtle changes in the functional integrity of the cochlear outer 
      hair cells, are used. First, DPOAEs (distortion product) and TEOAEs (transiently 
      evoked) of 24 subjects were compared before, immediately after gunfire practice, 
      and after one hour of non-exposure. Secondly, both types of OAEs were evaluated 
      in 31 subjects before and after exposure during a five-day military practice. 
      Significant differences existed between the ears in most cases; the emissions 
      from the right ear had a tendency to be more robust. There were no significant 
      changes in OAEs either before and after exposure, or in the second experiment 
      over multiple days. These findings suggest that the HPDs are able to prevent 
      cochlear damage.
