Eye color and pure-tone hearing threshold.
Pure-tone hearing thresholds at test frequencies, 250, 500, 1000, 2000, 4000, and 8000 Hz, were compared for 149 unambiguously blue- vs 172 brown-eyed individuals. Blue-eyed subjects ages 17 to 30 years (M = 20.3) had a significantly elevated mean hearing threshold at the highest frequency tested.
