A U.S. friend is building a three-story wood structure here in Japan that will house his imported foods business, and also have a small cafe-gallery, with his family’s living quarters on the top floor. He’s planning for hardwood floors on the second and third stories, and is worried about noise propagating from the upper to the lower. He has the joists (and I assume subflooring) installed, but apparently not the hardwood flooring or ceiling sheetrock. Aside from putting carpet on the upper floors, is there anything he can do, reasonably speaking, to help insulate the upper stories against noise being transmitted below?
Thanks (in advance) for any advice

Norm, telling to try resliant channel as the strapping for the floor joists, installed correctly this will help to reduce the noise, he may also want to insulate the joist spaces and install two sheets of drywall, this all costs $$ but will help reduce noise, or he could just walk softly.
*Thanks HWC; I'm collecting responses from a number of informants and packaging them to send to my friend. Since he's already gots the joists installed, it may be too late to use resiliant channel, but I'm hoping he at least has headroom to put in a minimum hanging ceiling with insulation behind.Visit Virtual Fujino, Japan!

*If you go with a double layer of drywall - use two different thicknesses. It disrupts the resonance of noise through the ceiling.Terry
*Norm,I am not an informant but the resilient channel gets fastened to the joists (perpendicular strapping) and the drywall gets hung to that. Best of luck.

I was thinking of something along the lines of joist hangers (just shows you how much I don't know about housebuilding.) Also thanks to TLE for the tip about drywall thicknesses.Visit Virtual Fujino, JapanGreen Gables: A Contemplative Companion to Fujino Township
*Hey Norm:I thought you took your shoes off when you entered a house. I also thought you put on those house shoe - sock thingys. See you at The Oak.Ivan
*Hotels and motels commonly use lightweight concrete on top of subfloors. It reduces sound transmission and increases fire resistance, I think.
