Yeah, you'll hear it a lot from the outside. Not so much inside. What you will hear if you have knock is a tiny tap/pop sound that will be rather quick and then disappear under high load. It will sound out of place and not uniform to other less 'heavy' acceleration. I'm sure everyone has heard it at least once (whether they know it or not) within the first few hard pulls as the engine is learning the timing curves and fueling.
