Fig. 5.

Reconstruction accuracy ± 1 SE of the speech envelope of the foreground for younger and older adults. A: results in quiet and in all of the noise conditions tested. The black horizontal line shows the noise floor. Older adults' reconstruction accuracy is significantly higher in quiet (P = 0.001). However, as a completing talker is added to the task, the differences between the 2 age groups are reduced. B: reconstruction accuracy in quiet and at −6 dB for the 3 integration windows tested: 500, 350, and 150 ms. Significant differences across the 3 integration windows were found only in older adults in both quiet (P = 0.001) and noise (P < 0.05). *P < 0.05, **P < 0.01, ***P < 0.001.
