White noise, air con waves of sound for sleep; calming; meditation; sleep; focus

The waves of sound can help calming your mind. It is good for meditation and sleep. Just close your eyes, breath in and out slowly. It can also act as a kind of white noise for you to focus.
The sound is derived from air conditioners. I accidentally found it quite soothing in the form of waves during the making of my music project of music concrete at school. So I made the video.
