Background: Age-related sleep architecture alterations include fewer N2 sleep spindles, shorter N3 duration, and Slow Waves. This is linked to age-related decline in cognition. Auditory stimulation (AS) improves sleep oscillations. Aim: This study examines how open-loop AS impacts spindles and SW in young (YNG) and older (OLD) individuals during N2 and N3. Methods: A nap polysomnography was conducted on two healthy adult groups: YNG (n=8, 19–34 years) and OLD (n=6, 50–65 years). In N2 and N3 stages, a 20s AS was given, with 2s of 13.75 Hz modulated pink noise, 8s of constant pink noise, and 10
