Neural responses to amplitude-modulated noises with different envelope shapes for younger and older adults. (a) Neural time courses, (b) P1 amplitude (left panel), and N1 amplitude (right panel) are plotted for each age group (younger, older) and envelope shape (ramped, damped). Topographies in (a) represent mean P1 or N1 amplitude (averaged across envelope shapes and carrier frequency bands) for each age group (younger, older). Error bars indicate SE. *p < 0.05.
