quick question: any noise when installing Snow Leopard?

[Parallax124]

I am in a library and have my disc to upgrade to Snow Leopard. I want to do it now while I'm reading, but I'm afraid maybe there's some sound effect that will happen when the installation is complete (like there was when I booted up my macbook for the first time). I have the volume set to mute--will it stay on mute?

I wish I had some headphones with me just to make sure nothing came out the speakers, but I don't.

All i could hear was the noise of the disc drive spinning, and the fan speed increased quite a bit too.

No sound effects though.
