Yeah. Sound is the vibration of matter larger than a proton.
It's a mechanical thing which requires material continuity between source and receiver.
If there is no receiver, eg a tree falls in the forest and no one is there, it's simply vibration. There is no receiver to convert those vibrations into sound. For the critters in the area with ears it is an event, and there is sound.
Now space is filled with vibrations of particles and waves smaller than proton, and those still take a receiver to interpret them if one is a "being" the size of a human. It happens that we have eyes which are those receivers for a narrow band of those vibrations.
