This looks silly, but is actually a good idea, if you are a close relative and need your away to be in the room at one of those loud weddings. Of course, the best option would be to hire a lower-volume band (I'm available), and next best would be for the baby to not be in the room.
But, if you need to have the baby there, or if you're one of those people who feels compelled to park your infant right in front of the speaker during the dance set, these are a good b'dieved option.
