Loudest Animals in the World

There are many obnoxiously loud sounds in this world. Upstairs neighbors, for example. The Amazon delivery person when your newborn is trying to sleep. Dogs. Mother-in-laws. 
If you lived next door to a blue whale, however, your eardrums would no longer work. Even two screaming in-laws will never be loud enough to compete with the loudest animals in the world, so be glad you don't live near these.
