not very loud, the one we replaced was louder, now no one gets woken in middle of the night when someone uses it.
You do need to make sure you have completely pressed the button. It could seem like a second or two.
Since this is a dual flush toilet, the dots are just an indicator for light flush (3 dots) vs. full flush (9 dots). I know of no other significance.
I think it is a general reference and not an exact ratio: the 3 dots is for #1 as it requires less water to flush, leaving 9 dots for #2 when more water is required (this 9 dot button is equal to a standard flush)
The toilet itself is 26.50" in depth, but is made to be 1" from the wall on a 12" rough in. So the front of the bowl will end up being about 27.50" from the finished wall. The actual spec sheet is on their website, and attached here for you now.

Yes it can connect to the floor as that’s how mine was installed.
Ran, They are not the exact same product, but have similar functions. Although not depicted very well in the photos there a aesthetic differences between the two items. Sincerely Your American Standard Consumer Connections Team.
