Imagine the door to a theater is opened and you are standing outside. How is it possible that you can hear the sound of the movie or play, even if you cannot see the screen or stage?
The sound waves diffract much more than the light waves, so they bend and spread as they move through the doorway.
The darkness in the theater absorbs light, but not sound, so you can hear.
Reflection only happens with sound waves, not waves of light, so the sound waves bounce out to your ears.
