Listen! Hear! 

 - Washington, D.C.  National Geographic Society  1982 
<br/><br/> Color video; 15 minutes.  There are sounds all around us. Our ears are always turned on, picking up sounds wherever we are.   We hear sounds and, if we listen, we can tell where they're coming from, how far away they are, and if they're familiar.  But what do we know about how we hear?  Listen! Hear! tells us about our sense of hearing.
