The interrelationship among measures of pure-tone hearing level thresholds was explored to determine if a simple summary statistic could be used to describe hearing sensitivity. Pure-tone thresholds from 250, 500, 1000, 2000, 4000, and 8000 Hz were assessed for 308 observers. High correlations were observed among the various pure-tone measures, even when separated by several octaves. There was also a high correlation in the sensitivity of the two ears for each observer. The mean threshold, computed including all test frequencies and both ears, was shown to have an average correlation of 0.88 with each of the component measures. This simple average is thus recommended as a valid, yet uncomplicated, summary statistic for reporting the auditory sensitivity of groups.
