This is, this second, working for me!
Put earphones on & play these 3 frequencies to cancel or white noise out the ringing in your ears & other benefits
Open 3 tabs @ http://onlinetonegenerator.com/ on your cell
play 396 on 1, 417 & 528 on the other tabs, at low volume; voila, a relaxing lurk experience
That’s very cool, thank you!
