Effects of simulated aircraft noise (noise 30 and 60 reflecting 30 or 60 playback aircraft noise events) on endothelial function (as measured by FMD) and (lower right) stress hormone levels of healthy volunteers. The administration of the antioxidant vitamin C (upper right) was associated with improved endothelial function, demonstrating a role of oxidative stress. Adapted from Schmidt et al.
