Can loud noise harm a fetus?

I know it is proven that a fetus can hear sound from outside the womb. Just as reading or singing to the unborn can help fetal brain development. I would assume that very loud noise may not be good for a fetus, just as a very loud noise is not good for anyone else either.

When my wife was pregnant with our first daughter we went to see Gladiator in the theater. Our daughter got very active during the loud scenes. I guess she heard it all and didn’t like it. People sing to their fetuses all the time. They seem to hear that and find it a more pleasant experience.
