When I walk in my master br upstairs, I can here like bouncy metal clanging sound. Initially I thought is from the roof cavity and today only realise that is from the subfloor since when I was on ground floor and someone was in the master br above me, I could hear is very clearly. I rechecked old photos of that area and my engineering drawing , there is a small pyrda strap in that area. 1/4 of the size of the master br. and also a heating duct. There is no sewage pipe work in that area. Any ideas?

I can imagine that if it's not tensioned and fixed off at each joist correctly then it could cause noise as the floor deflects.

On my engineering drawing it's says pyrda strap. Lucky is isolated to the master br. Where the small strap is there. Another area with larger strap bracing it was fine. I guess only way to fix is pull out the carpet and ripped the yellow tongue board out??
