in your ears there are receptors which feels the wave of sound and informs your brain about it. you brain translate these waves into the voice.
2) when any bid obstacle blocks the path of sound waves then these waves reflect from that obstacle and returns.
these returning waves are known as ECHO.
3) sound waves travel through the molecules in air.

Sound is heard by stimulation of the tiny hairs in the cochlea in the inner ear. This occurs after the eardrum has been caused to vibrate, then the 3 bones and then the cochlea.
an echo is a reflected sound wave
sound waves travel through a medium(material) . they are longitudunal that vibrate in the same direction they are traveling, waves with first a squeezed in area and then a spread apart area.
