Effect of kurtosis correction on the measured human NIHL data. AHFNIHL is percentage of the subjects having a higher HTL by 30 dB or more than the control group. Solid line with filled diamond symbol represents the CNE-NIHL relationship of the group exposed to Gaussian noises, dashed line filled square symbol represents the CNE-NIHL relationship of the group exposed to complex noise, and dotted line with filled triangle symbol represents (kurtosis corrected CNE) CNE′-NIHL relationship of the group exposed to complex noises. CNE′-NIHL curve of the complex noise becomes much closer to the CNE-NIHL curve of the Gaussian noise, which the kurtosis correction reduces underestimation of the risk of complex noises.
