Hi Also, from the pictures it does not look like a high traffic area & there seems to be some distance from your neighbors. Why the floating floor? looks like a nice cement slab floor already. with that said,My cement floor was a bitch to jack hammer out ducts for the audio/power lines. Ed

There are many reasons why the floor is floated:
- In Holland, the water is so close to ground level in the earth, that the building techniques for stabilizing those buildings include resting it all on big concrete poles, often deeper than 12m in the ground. With time, there is a high risk that a big cavity will appear just under the concrete floor. When it happens, the floor is therefore very sensitive to vibrations and resonates very easely.
- it is still an industrial area with trucks driving every now and then. Because of the phenomenon described first, and the fact that a big truck engine running at low speed will generate a lot of LF (aerial and solidian transmission), decoupling was judged necessary.
- The heating system (tube circuits) is hidden in the existing concrete floor, therefore, it is impossible to risk damaging it in any way (even drilling in it is out of the question). Furthermore, because of the phenomenon described higher, degrading it is clearely not an option either as it would compromise the building's integrity.
- The direct neighbour plays loud music from time to time which should never disturb Darius. The neighbour is directly behind the wall on the left of Darius's room.
So Darius will be sitting in a room decoupled from 13Hz and will be therefore isolated from all possible noise pollutions. The new floor will also contain all ductings for audio and electric cables.
