Matrix speech reception threshold (SRT) for the 2 masker types: speech-weighted noise (SWN) and a competing talker (CT) across the adult lifespan. Two regression lines with confidence intervals (shaded areas) were fitted to the data and indicate a supralinear increase of the matrix SRT with advancing age for both masker types. A significantly steeper slope was found when CT was used as masker compared with SWN (see Table 2). SNR, signal-to-noise ratio.
