   Echo is a single reflection of a sound - the kind you hear when you   
   shout "Hello" near a cliff.   
      
   If you put together many echoes, arriving from different distances   
   into a jumble that you can't distinguish - that is reverb. You get   
   that in, say, a large church.   
      
   Feedback is a situation you only get when you have an amplifier and a   
   speaker. The sound arriving from the speaker is a little louder than   
   the one that originally hit the microphone, so that comes out of the   
   speaker a little louder still. This loop will build until the system   
   howls. You cure it by turning down the amplifier so the sound from the   
   speaker is always a little softer than the original when it hits the   
   microphone.
