Nope. In fact I have made my TAF even louder - it's in the cab on Addams, dropped the playfield support arm down so the knocker hits that instead of the cab and it has the effect of turning the whole cab into a massive amplifier
Seriously the LOUDEST knock I have heard . During Seance mode it really does sound like the dead are trying to escape from inside the game 
'Knock 3 times ' .......
