Pupil Dilation Responses
Human pupils may dilate for various reasons, including memory load, cognitive difficulty, valence, arousal, pain, and so on (Beatty, 1982). For single responses, Hess (1972) reported that such dilation would occur 2-7 seconds after emotional stimuli were presented and suggested faster dilation for stronger stimuli. Partala and Surakka (2003) showed that there was first seemingly no response for about 400ms, and then a steep increase in pupil size peaking at 2-3 seconds after stimulus onset, using different sounds (baby crying, laugh or regular office noise).
When performing a cognitively demanding processes, pupils dilate in responses to mental workload of the task and peaks at about 1-2 seconds after the onset of demand (Beatty, 1982), and constrict after the task is completed, either gradually (Kahneman and Beatty, 1966; Hess, 1972) or instantly (Bernhardt et al., 1996).

Does noise give dialted pupils?
Yes, exposure to loud noises can cause dilated pupils. This reaction is part of the body's fight-or-flight response, triggered by the sympathetic nervous system when it perceives a potential threat. The dilation of pupils allows more light to enter the eyes, which can enhance vision in low-light conditions, helping an individual respond to danger more effectively.
