ELI5: Where does the sound go in space?

Title might sound stupid, but if all sounds are vibrations moving through the air particles, Without them in space, We have no way of Transferring that vibration from one place to another.

When a action that would cause a sound on earth is made in space, Where does the energy that would be the sound go? And if it doesnt go anywhere does the energy/vibration ever cause a problem for anything?

The short answer is "it turns into heat or velocity".

On the ground, sound is a two-part mechanism where a source, such as a hammer impacting a metal surface, causes a "shockwave" that goes through the air, and than that shockwave impacts your eardrum which is set up to tell your brain "BONNNNNGGGGgggggggg". 

So let's put that hammer-impacting-metal situation for a metal plate on a satellite in vacuum, and then in a pressurized room in the ISS.

In vacuum, the hammer hitting the satellite transfers all of the sound energy into the hammer, the satellite, and possibly whatever thing is holding the hammer, because that sound energy has to go somewhere and there's no air to receive it. The hammer blow may push or spin the satellite a bit (the velocity part), but its vibrations only flow through the structure of the satellite and bounce around until they're absorbed and their resulting energy is transformed into a very tiny increase in heat.

In the air-filled ISS, the same thing happens, except the air works the same way as it does on Earth. Eventually the sound is absorbed by surfaces and, again, transformed into a very very tiny increase in heat.
