Space Station Question?

[acidrain]

<p>Iam sorry in advanced if this is the wrong area to post this question.</p><p>My question is in regards to the space station, it might sound like a silly question but my 9yr asked me this question and i didnt know how to answer it. She asked me if it was loud on the space station or was it extremely quiet as ive told her that space is cold and quiet, so is the station loud and if so does the people onboard use ear pieces? I realize that it is a wierd question, though i need help here you all!</p><p>Cheers,</p><p>A </p>

<p>The ISS is a working spacecraft, so think of the working spaces of a ship, aircraft&nbsp;or even a building, there are lots of things going on and many noise sources.</p><p>Parts of the ISS can be quite noisy, mainly because of the need for strong air cirulation to remove suspended particles which can cause health and equipment problems (on earth they all settle to the floor where they can be swept or mopped up).&nbsp; This is a requirment for all space craft with inhabited volumes - the space shuttle has 8.5 air changes and hour and payload bay modules&nbsp; (spacelab/spacehab) 6.</p><p>Mir was&nbsp;noiser, and the ISS benifits from the experience of the earlier station.&nbsp; Future spacecraft will be quieter.</p><p>Jon</p> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>
