What does an engine that is detonating sound like? Fortunately I have never had this problem with anything I drive but I want to know so that I might be able to help somebody fix their car someday.

If you hear a rattling when you accelerate slowly without shifting gears, that's pinging or pre-ignition, which can lead to detonation. Sometimes you can't hear detonation, but it's doing a number on your pistons whether you can hear it or not.

How do you know if it is happening if can't hear it? Is their any other signs to look for?

White or silvery particules on the spark plugs, usually means detonation.
