What sound is that?

Two people are in a dimly lit indoor space, likely a hallway, with a curtain and wall visible in the background. The person in the foreground, who is bald and wearing large sunglasses, adjusts their sunglasses while looking at the camera, then moves them up onto their forehead, revealing their eyes, before lowering them back down, while the second person, with long hair and sunglasses, remains in the background.
