Figure 1

Pure tone thresholds plotted by age for each ear (right=red, left=blue, n=37) based on evaluation at NIH clinical center. R2 and slope of the regression line are shown for the right ear; p<0.0001 for individual frequencies and the four-frequency pure tone average (4F-PTA). Dotted line at 20 dB HL represents the upper limit of normal hearing. R2 and slope of the regression line for the left ear are not significantly different (data not shown). Dotted line at 20 dB HL represents the upper limit of normal hearing.
