Nature Sounds: Many people enjoy hearing the calming roll of ocean waves, the trickle of raindrops, the gentle chirping of rainforest animals, or the powerful roar of thunderstorms as they drift off. These sounds often rise and fall in volume and intensity, which you may find relaxing.
During each soundscape, participants also performed a task to measure their attention and reaction time. Their heart rates were monitored as well, to indicate changes in their autonomic nervous systems—the system of organs involved in involuntary processes such as breathing, blood pressure, temperature, metabolism, and digestion.
