Yep - that's liking turning up the radio to cover up a bad noise. It isn't fixed you just can't here it!
A new knock sensor or redo the connections and ground. Make sure your timing is set properly and use the proper fuel.
You may also want to try some of the de-carbon techniques (water introduced while running to "steam" out the carbon. If the combustion chambers have excess carbon you'll increase the tendency for pre-ignition (AKA detonation).
Fix it right and you'll be much happier in the end...

And knocking all the way without you hearing it. It does matter where the
knock sensor is and as bad as it looks, is not hard to replace properly. It
will pick up some of the knock where it is, but not soon enough and will
cause damage over time, sooner if you use regular gas instead of high
test/super/gold or whatever they call the 90+ octane in your area. Your
problem may just be caused by a poor connection on the old one.
