AB  - Impulse peak insertion loss (IPIL) was studied with two acoustic test fixtures 
      and four hearing protector conditions at the E-A-RCAL Laboratory. IPIL is the 
      difference between the maximum estimated pressure for the open-ear condition and 
      the maximum pressure measured when a hearing protector is placed on an acoustic 
      test fixture (ATF). Two models of an ATF manufactured by the French-German 
      Research Institute of Saint-Louis (ISL) were evaluated with high-level acoustic 
      impulses created by an acoustic shock tube at levels of 134 decibels (dB), 150 
      dB, and 168 dB. The fixtures were identical except that the E-A-RCAL ISL fixture 
      had ear canals that were 3 mm longer than the National Institute for Occupational 
      Safety and Health (NIOSH) ISL fixture. Four hearing protection conditions were 
      tested: Combat Arms earplug with the valve open, ETYPlugs (R) earplug, TacticalPro 
      headset, and a dual-protector ETYPlugs earplug with TacticalPro earmuff. The 
      IPILs measured for the E-A-RCAL fixture were 1.4 dB greater than the National 
      Institute for Occupational Safety and Health (NIOSH) ISL ATF. For the E-A-RCAL 
      ISL ATF, the left ear IPIL was 2.0 dB greater than the right ear IPIL. For the 
      NIOSH ATF, the right ear IPIL was 0.3 dB greater than the left ear IPIL.
