Linear regression models for SRTHP in noise (SiN) or in quiet (SiQ). Regressions were performed on the entire cohort as well as in subgroups of normal-hearing (NH), or older (OLD) subjects. All models had a normal distribution of residuals, and a colinearity (vif) factor below 1.61 (i.e., independent parameters). Significance codes: ***p ≤ .001, **p ≤ .01, *p ≤ .05.
