Can anybody comment on the science behind this explanation?

I can confirm sound travels farther/faster in lower temperatures. When it is warmer, air particles are moving faster and disrupt sound waves. I would assume humidity would also have a dampening effect. Snow definitely has a sound dampening effect.

I think I learned this in Physics 12. After that, i did notice that on cold/dry days I could here the sound of the full serve gas station near my house and only on those days.
