Suffice to say that 68083 is having a bit of a youtube session at the moment.

I think I might need to get me a couple of those for a school project......

But seriously I probably will. Because I'm building the ultimate alarm clock. And I think one of those and a speaker if you want it to play an MP3 (a possibility) will make it beastly.

Yeah, if that truly was the case, you'd be deaf.

01001010 speaks the truth.

140db is the equivalent of a jet engine. Now add two of them together.

Death of hearing tissue occurs at 180db.

This chart even states even short term exposure to 140+ could cause damage.

Two of them together would be 146db. It would sound 4 times as loud.

Sound volume doubles every 3 Hz, but amplitude doubles every 6 Hz.

Two would double the amplitude (assuming they were operating perfectly in phase) and that means it'll sound 4 times louder.

At least I think so. Someone needs to confirm this. Because I'm not 100% sure this is right.
