I have the ability to create ringing in my ears, do you?

As far back as i can remember, i have had the ability to flex some muscle in my inner ear that vibrates im guessing my ear drum to make it sound like a continuous ringing sound is being generated for a period of up to 30 seconds. If i flex that same(possibly different?) muscle in my ear it creates like a popping sound that you might feel if your ears were to pop from altitude pressure release.

I used to also use this to protect my ears if i knew a loud sound was going to occur like an explosion.

This sound appears that only i am able to hear it/feel it - and no one else can. This is not the result of a disability, my hearing is perfect and i am young and healthy. Additionally, produce it - i control it and create it, it does not happen on I its own.

What is this and is there anyone else out there that can do this too?

Interesting... I can't do it, but I can make my vision go blurry, why are we equipped to do such things?
