Thanks scotlandx,
Your advice is very, very much appreciated and makes perfect sense. I will get some advice as suggested. All I want is the owner above to return the acoustic characteristics of his lot to that I was experiencing before the wooden nightmare was installed. I have been putting up with constant booming and banging noises till 2am since Feb last year and I am getting a bit desperate for a good nights sleep. I am a bit worried that the owner upstairs will do a half a***ed job and say its resolved or use his current strategy of asking the tenants to tippy toe for a few months till, in his mind it has blown over. It would be nice if he could just see that the installer gave him bad advice and he got a dud install and just fix it once and for all. Had the roles been reversed this is exactly what I would have done.
Again thanks for what is sensible advice. I was going to ask my strata lawyer but he charges like lawyers do for everything, including asking how things are going 
Cheers
andyj
