| Popis: | This study used a Monte Carlo simulation to evaluate the reliability of pure tone audiometry while incorporating information about the population distribution of thresholds. Results confirm that audiometric error (outcome threshold minus modeled threshold) is symmetric when simulated data are binned by modeled threshold. However, when data are binned by outcome threshold, the error depends on the relative distribution of modeled thresholds. When a realistic distribution is used, outcome thresholds of 0 dB HL show the lowest error rate. Bins with outcome thresholds 0 dB HL show a positive median error (outcome threshold > modeled threshold). These results suggest that a substantial proportion of individuals who obtain a very good threshold during audiometric testing (−5 or −10 dB HL) are individuals who actually have higher thresholds, which are being underestimated. These findings are relevant for hearing conservation programs, which monitor for upward shifts from baseline thresholds.
