Pupillary response interpretation to white noise audible stimuli

This paper is focused to analyze the pupillary responses elicited by an audible stimulus (white noise). The stimulus durations were 150 ms, 250 ms and 2 s. And each one was applied twice, at 5 s and 15 s. The test was performed on photopic conditions in 5 men subjects from 25 years old to 29 years old.
