• Description:
  The Blast Overpressure (BOP) data from the U.S. Army Albuquerque studies were analyzed with population-average (generalized estimating equations - GEE) and subject-specific (generalized linear mixed models - GLMM) logit models using five different noise exposure criteria as independent variables: MIL-STD-1474D for the free-field condition, the A-weighted equivalent 8-hour level (LAeq8hr) for the free-field and protected conditions, Auditory Hazard Assessment Algorithm for the Humans (AHAAH) warned and unwarned status of the middle ear reflex for the protected condition. The purpose of the current analysis was to determine which noise exposure criterion best characterized the BOP injury data. The noise exposure criteria that yielded the best fit as judged by the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) for the GLMM and the quasi-likelihood under the independence model criterion (QIC) for the GEE models was the free-field LAeq8hr, followed by the MIL-STD-1474D, protected LAeq8hr, unwarned AHAAH, and warned AHAAH. Generally, the free-field data for LAeq8hr provided a better fit to the BOP injury data compared to the protected data.
