    Default Talk about SPL


    I just watched "The Universe" on the History Channel. It was about the sun, and mainly about the huge storms that puke out vast clouds of charged particles toward earth.

    But one part was talking about how the corona gets to be millions of degrees, when the surface of the sun is only thousands of degrees. The key was when they got a satellite to be able to take hi-res pics of the surface, and it's just a boiling cauldron. These areas that rise to the surface, cool, and then fall back inside, are the size of Texas, and they rise and fall in just 5 minutes. There are millions of these events all over the surface, in continuous fashion.

    Then the scientist comes on and tries to describe what's happening. "It's like you covered the entire surface of the sun with huge speaker systems, all playing at the volume of the loudest rock concert. It's a very loud place," he said. That huge SPL is what is causing the atmosphere to superheat.

    So next time you're at a really loud concert and you feel your head getting warm, you'll know why.

    Default I can understand that...


    In our speaker boxes, the inner pressure is transferred to a minute amount of heat in sealed boxes. Sometimes there is polyfil to absorb it. If you infinitely multiply this thermodynamic application, I can imagine it would be loud, and hot. I also agree that we can't hear the spl from the sun, due to the vacuum that encloses it.
    (How many cubic feet was it to put the sun in a box again?)
