D. Pure Tone Data Based on PTGs

We submit that the distribution of unaided mean scores for SAC and SOAC are more useful because they are different for each of the eight PTGs. As noted in section C, the GHABP data also are quite different across the PTGs. By using PTGs we know the effect on unaided communication for various degrees and configurations of hearing loss. For those who wish to use PTGs in the fitting and rehabilitation of hearing loss, this site makes it easy to use the best ear thresholds and determine the client's PTG.

The mean hearing thresholds for the subjects in the HEARx data and our n=1243 data sets were compared after classifying them into the 8 PTGs. As can be seen in Figures 1-4, they were very similar and show the value of using the exclusive grouping of PTGs.
