What's the difference between reverb, echo, and feedback?
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.
