It is erroneous to think that just because a pain or difficulty can be offered to God, irritations at Mass are helpful. Any irritation can of course be a help, in that we can offer it to God, but our worship should not cause ear pain nor any other kind of pain that can be permanently damaging. We are to mortify the flesh but we must not damage ourselves to the point where our duties of life are threatened. Loud volume is very unhealthy. At the Mass we should be recollected. Everything about the Mass should contribute to recollection. Liturgical features that work at cross-purposes to that should be eliminated.
