4 Hours Fire Crackling and Crickets Chirping at the Beach - Soft Ambient Sounds for Sleep and Study

Natural sounds help you relax because, unlike artificial sounds they are constant noises of a pleasant pitch, at a constant volume. Your brain interprets them as non-threatening sounds, which helps reducing your stress level and making you more relaxed. Also, they can mask other sounds, (furniture creaking, people walking, traffic etc) that might keep you awake.
