How does the sound produced by a musical instrument reach your ears? Astronauts need radio transmitters to talk to each other on the moon. Why?

(N/A) The sound produced by a musical instrument causes the air molecules to vibrate. These vibrations are transmitted through the air from molecule to molecule until they reach our ears. Upon reaching the ear,these vibrations cause the eardrum to vibrate,which is perceived as sound. Since sound is a mechanical wave that requires a material medium (like air,water,or solids) to propagate,it cannot travel through the vacuum of space. Because the moon has no atmosphere (a vacuum),sound cannot travel between astronauts,necessitating the use of radio transmitters,which use electromagnetic waves that do not require a medium.
