Relationship between age and other measured variables. (A) Absolute hearing thresholds at 12 kHz (HFTs); (B) speech reception thresholds for disyllabic words masked by an international female fluctuating masker (SRTNs); (C) thresholds for detecting a silent gap (a pause) between two pure-tone markers (GDTs); (D) thresholds for detecting frequency modulation (FMDTs); (E) ABR wave-I slope; and (F) inhibition scores in the SCWT. The insets indicate the proportion of variance explained (R2) by a linear relationship and the probability (p) of a non-zero regression line slope occurring by chance. Points represent individual scores. Solid lines depict linear regression lines; dotted lines represent the regression's 5 and 95% confidence intervals. ABR=auditory brainstem response; FMDT=frequency modulation detection threshold; GDT=gap detection threshold; HFT=high-frequency threshold; SCWT=Stroop Color-Word Test; SRTN=speech reception thresholds in noise.
