Well, it is not as though a Catholic Church is Sanctified and dedicated to the Worship of the one living and true God and so one can't reasonably expect it to be as quiet as, say, a library.
And "stand and greet each other" really says it all about where we are expected to direct our focus.
Go to a Chapel/Church where the 1962 Roman Missal is used vs your local Church where the N.O. is used. The difference is stark.
