I have built my first wood houses since few years, European class A+, short answer is yes however less than concrete houses. Long answer structure is from lower flat and upper is: - fibrous plaster + finishing with it's support structure - mineral wood 100mm think between wood beams (250mmx100mm) - OSB panel on top of beams, 30mm - sandwich panel composed of wood wool (20mm) and fibrous plaster (30mm) - thin (4/5mm) wood wool panel - laminated floor If I walk normally I do not hear too much downstairs, otherwise well... Noise passes, far more than classic concrete + rubber coat + background and floor tiles... Also when I move I hear "casual noise" from laminated floor friction. Not much but a bit yes... IMO sound propagation is due to the fact that wood structures are lighter and elastic than concrete so vibration passes far easier and it's hard to stop them...
