Why if someone is shouting you can hear it from hundreds of meters but if you were next to them you could hear them but not feel the air moving but you can feel a fan if you’re close to it but you cannot hear it from far away?
(The bad grammar makes it even more eli5)

Sound is a back and forth motion of the air. The molecules move, at most, a few millimeters, and they make this movement hundreds, thousands, or tens of thousands of times a second. Unless it is very loud you won’t feel this at all.
A fan just causes a lot of air to move. A byproduct of this is some vibrations but they are relatively quiet. The moving air quickly slows down and mixes with other air.
