... ultrasound for about an hour or 2. Are there any long term affects of exposure to ultrasound from 10-20hz
What if an adult gets his headphones that are able to play 20hz with bass and everything and plays?

I'm planning to listen to it for at least half and hour but my goal is an hour. Hoping that I don't get bored and go for more. I'm planning to do it during 3am when everything is quiet and in a dark room and I'll be starting at the same exact spot in the ceiling and see what's happens for science.
