Its either your ears, or ghosts

Could just simply be your ears? Or some appliance emitting the noise. Don't see how that exactly fits as a conspiracy. :|

It happens to me, exactly like that crazy guy!

Its nothing to worry about, it happens when you are doing something loud, or just have your tv on fairly loud, then you turn the noise off suddenly. Its like your ears trying to cope or something

Why is this even in the conspiracy board? You've obviously been listening to music/TV way too loud and your ears ring as a result.

You'll give yourself tinnitus if you keep doing it, no paranormal here.

My dad fell of a crane at work and hears that noise constantly.

Many people experience an occasional ringing (or roaring, hissing, buzzing, or tinkling) in their ears. The sound usually lasts only a few minutes. Ringing in the ears that does not get better or go away is called tinnitus. You may hear a sound, such as a ringing or roaring, that does not come from your surroundings (nobody else can hear it). The sound may keep time with your heartbeat, it may keep pace with your breathing, it may be constant, or it may come and go. Tinnitus is most common in people older than age 40. Men have problems with tinnitus more often than women.

or it can simply be "mad snail disease"

That happens to me too, it's wierd but it doesn't bother me.

Oh my god, I hate that, especially when I take tests in class...

Its normal, it is your brain creating sensory signals in lack of other sources.
aka: if it is too quiet, your brain will make its own noise. Yes this was a copy and paste so what
