After my third breakthrough (sometime in December 2010), I began to hear a persistent tone. It's very high pitched, similar to how you can sense an old CRT or tube TV being on even when the screen is blank. It's not auditory in nature, like how your ears ring after being exposed to high dBs (quite familiar with that phenomenon from clubs/concerts).

It is not annoying, I definitely "hear" it when it is very silent around me, but can even hear it when I want to if having a conversation. It's just "there."

So I have come to the conclusion that I either broke my brain or woke my brain...

Which is it?

Then my brain is broken too Im now hearing this tone 24h/24.

Being a new ager though I think it may have to do with our consciousness level increasing, information being downloaded into our consciousness.

Time will tell.

I don't get that with sound, but I bring visuals everywhere I go with me, and I can relate to everything you said on the visual level

iu wouldn't be so optimistic hypnos..i really don't know if it could be carebral damage or other things it could be tinnitus too..maybe *could be* that spice damage the acoustic nerve,i don't think anyway but..

or it could be attracting attention to the tinnitus

Yeah man, basic tinnitus. I've been suffering from it for over a decade. Sometimes you can hear it more clearly, sometimes not. But in silence it is always there with me, dang annoying high pitched beep that never ends

Same for me, basic tinnitus. I developed mine after a severe beating I took at a party years ago. Sometimes its worse than others and the carrier wave seems to aggrevate it. For the most part it doesnt bother me as I always sleep with a fan on (white noise).

Unfortunately I too suffer from tinnitus. I got it after standing next to a speaker at a psytrance squat party about 8 months ago. I think playing the drums when i was younger didn't help. I got used to it after a while.

I suffer from owl hoots and dove coos when I yawn.

Are you talking about ringing ears? Everyone has that. If you've ever been in complete silence or your falling asleep, and you focus on that high pitch. It can get louder, but so can the carrier wave.
I hear techno style, rising pitches a lot in hyperspace. I believe that is my subconscious though, I heard dubstep in space, after listening to it for the first time.

swim is wondering if thids tinnitus is due to dmt or due to the fact you listen music at high volumes to festivals or parties..

That's the strange thing. I'm quite familiar with ringing ears after exposure to loud music (from my youth, that is). The tone I "hear" is much much higher on the audio spectrum. The "ringing" ear tone from loud music is much lower and very annoying.

On iboga, ketamine, and LSD I get that hum. It isn't noticeable to me all the time, but I do feel it when under the influence of the drugs I mentioned. From what I have been reading, too, it seems that at least lower doses of iboga bark feel much like a heavy caapi brew would.
