Tone does certainly matter and I don't think shushing is appropriate - it would not be taken well by me for sure. I would accept that there are circumstances where it is appropriate and acceptable to interrupt a colleague - for instance in a crisis meeting when you can hear they are going down a blind alley or talking without understanding circumstances that you can explain. I'd normally put my hand up and say 'We really need to be looking at why X is happening right now - it seem to be because...' or 'Sorry Ted, the site has already been moved to framework X so we will need to try ....' which I hope is adequately respectful.
