Chest Minecart/Chest Boat Sounds

I actually recently learned that closing a minecart with a chest or a boat with a chest emits vibrations.  However, this was very unclear to me in gameplay.  I always thought that they were silent and safe to open in deep dark biomes without triggering anything.  Sadly, I learned the hard way that this is not the case.  I am only requesting that you add the chest closing sounds to the minecart with a chest and the boat with a chest so that it is clearer that they do indeed make sounds.
