| DanDan, I have read Rod's book.
I have found ethylene propylene diene monomer (EPDM) rubber for decoupling walls from floor.
It it high density rubber used for sound transmission isolation of construction walls at very high loads. It is 5mm thick with 2mm (40%) compression under 9800kg load.
I calculated the weight of my room would be around 4000kg including frame, walls, ceiling construction without the weight of additional inner acoustic elements.
DanDan, Andre? |
