In old age, regression analyses yielded significant relationships between otoacoustic emission levels and ABR thresholds for all of the frequency bands tested. A) 1–10 kHz, F (1,84) = 12.90, P = 0.0006, r2 = 0.1331. B) 10–20 kHz, F (1,84) = 14.64, P = 0.0002, r2 = 0.1484. C) 20–30 kHz, F (1,84) = 10.08, P = 0.0021, r2 = 0.1071. D) 30–40 kHz, F (1,84) =10.70, P = 0.0016, r2 = 0.1130.
