10 hours of uninterrupted low frequency brown noise ranging from 20hz - 500hz with a black screen and no ads. Similar to falling asleep in the backseat of a car or on an airplane, low frequency noise can help relax your mind into a deep sleep. Can also be used for meditation, tinnitus or helping with infants sleeping. IMPORTANT: If you are using this as a sleeping aid make sure you turn off 'autoplay' in YouTube.
