Anything 140dB or higher is loud I think, even though 120dB is supposedly the threshold of pain. I think death can occur at like 170 dB or something, which I think is where your heart is at risk of stopping or fibrilating (sp?). The steam you see at space shuttle launches is not smoke, it is the steam created by the water below the rocket when it takes off. The launch is so incredibly loud, they have to deaden the sound with the water or the structure (that holds the shuttle up before liftoff) would collapse. This is like at 180 dB I believe. Needless to say it is stupid to play your music and try to enjoy it when it is painfully loud.</p></blockquote><p></p>
