Nonsense. You can hear a pin drop in our chapel just before and through the consecration. We have been warned against even coughing or sneezing. Absolute and total reverent silence.
This was my experience at the Tridentine as well. But sinkspur claims it was different in his experience.
I'm honestly curious to hear from the Orthodox in this, because I definitely remember reading about private devotions during the Orthodox Mass. It would be instructive to compare.
