Watch or sleep to or play in the background as you read, etc., this 1 hour long relaxing video of some waterfalls.
It may help some to relax or for insomnia to help them sleep.
Nature sounds like this waterfal may help you enter into deep relaxation.
A waterfall produces a calming noise similar to white noise.
I suggest you lower the bass setting on your speakers and adjust the treble setting to your liking.
