Inquiry (采购产品): HOME INSULATION-NOISE I have a condo on the first floor directly above the building's pump and othe machinery. when I put my ear to the concrete walls it sounds like running water and vibrates. It is very annoying throughout the condo. I also have the vents outside my window. Is their a solution to the noise inside and/or some kind of noise suppressor for vents? Someone told me that foam can be blown into the walls. Do you know contractors near Fort Lauderdale Florida?Thanks for any feedback. **** Hidden Message ***** Kathy shannon 02139 USA Company: none E-mail: kshannon@boston.k12.ma.us **** Hidden Message ***** kshannon@boston.k12.ma.us
