Task performance and noise may be stressors. Stressors activate the Sympathetic Nervous System. The present study was designed to examine task performance and noise effects on physiological responses such as SCR, HR and PPG as well as on behavioral performance during visual vigilance detection tasks. The effects of 75-80dB noise was also examined. We investigated the effects of conifer needle odor and soundguard on physiological responses and task performance. 76 college students participated in this experiment. Noise presented during task performance increased SCR and HR and decreased PPG compared to basal period(no noise, no task). We found that task and noise acted as stressors. The effects of noise during task performance increased HR, decreased PPG and did not affect SCR and behavioral performance compared to no noise during task performance. These results suggest that physiological responses are more sensitive indicators than behavioral performance is. The effects of essential oil from conifer needles are not significant, and soundguard increased behavioral performance and, in male subjects, decreased HR during task performance without noise compared to basal period. These results suggest that soundguard can loosen high-tension and increase behavioral performance.
