that's great that you were able to find workarounds. i always have my sound machine on too, but it's not enough. at one point i used anc headphones, but they gave me tinnitus and now i can't wear earplugs. i wish i could turn off the sound of the world lol
When I found out about how noise cancellation works (a soundwave with an exact-inverse copy played against itself cancels to nothing), it made me think... COULD we turn off the sound of the world? Would it ever be possible to have devices on the outside of a room, sending info at lightspeed, with a device inside the room beaming inverse sound waves to what it expects will reach your ears?
Just coming back to share something new I've discovered... brown noise!
White noise makes my tinnitus go nuts. Brown noise is so much calmer, relaxing, I almost start hearing other sounds in it. I generated 1.5 hrs, saved it as an mp3, and I play it from my phone speaker at night. I used a free program called Audacity to do it.
