Thomas,

Thanks again for the info, I really appreciate you input . It is almost my private forum here. I don't question your expertise  

I just wondered why there a difference approaches for floors. You told me that studio building design isn't voodoo,but a lot of calculations, but I do understand your point. I will contact the floor metal company to ask them about the self-resonant frequency of the floor.

But the floor design venting started me to think over the m-a-m wall designs, do the walls need to vent to? Can you vent the floor in to the walls etc.

Best regards,

Peter

Hi Thomas,

I found this: http://www.hifiladen.de/tools/index.htm?/tools/t_helmholtz.h tm

It is a room resonance frequency calculator, when i put in the dimensions of the space under the floor, does this say something about the floor resonance?

Best regards,

Peter

PeterDraaisma:
I have got the floor's resonance frequency according to the papers I got from Reppel bv is with a width of the benches,( hart to hart)60cm, 11.5 hz. So is this low enough?

Best regards,

Peter
