It's just the heavens moving around,,,,the sound of which change due to medium which it pass through.
The sound can go past through all the medium like gas, gooey and solid except vacuum.
In general, our ears hear the nouns of moving air through atmosphere(gas medium) and are used to it. But when u place a cup on your year, the medium change to solid and therefore the nouns changes.
