Medical researchers want to know if listening to music can reduce stress levels. They use the Cohen Perceived Stress scale [taking values from 0 to 40] to measure the stress levels of Senior Executives at the beginning of the study. The Executives then listen to ‘calming’ music for a period of five minutes before their stress levels are re-measured.
