I would imagine that in order to be a valid noise complaint the noise needs to be unnecessary. After all construction work has to be limited between certain hours precisely because it makes noise but they're allowed to make noise within those hours because the noise is a necessary thing to put up with in order to carry out construction.
I would imagine that they would argue that the ringing of the bells is a necessary part of the ceremony. Ring them at 4:00 in the morning probably would constitute a valid noise complaint though.
