Figure 5: Average IPIL results versus peak unadjusted peak impulse level. The E-A-RCAL ISL fi xture data are plotted with a solid lines and open symbols. The NIOSH ISL fi xture IPIL data are plotted with a dotted line and filled symbols. The right and left ear data from the NIOSH ISL fi xture exhibit close agreement, whereas the left ear IPIL of the E-A-RCAL ISL fi xture are consistently greater than the right ear IPIL data
