" This is our third visit to our nursery project here in Melrose Massachusetts where a young couple have bought their first home a two family home so that the rental income helps defray the cost of the mortgage and they're busy remodeling some bathrooms and a bedroom getting ready for the first baby's arrival. Any day now. Nick and Maggie live on the second and third floor of this big 1895 house they've already insulated the roof up above there to help defray the cost of heating. In our tough New England winters now it's time to talk about insulating the interior walls for sound attenuation. Because after all baby needs a quiet environment as well as a warm one. -- bronze after the Ph.D. in child psychology and you're visiting us here at this project and I guess one of the things that would concern us is why is it important to have peace and quiet around the nursery."

" Well a child has to sleep. And children really find it much easier to fall asleep in a quiet room. Now you might say -- me but the child's gonna make some sounds. Those of the sounds for parents and when the child makes sounds chipping in fact. It's usually a cry because child's wet the child's hungry. Other child is uncomfortable. And -- cues that parents have to listen to and attend to and quiet the child. But when the child has to fall asleep it's important for the child's development that the child has been a good actually even though it's broken up. By feeding -- sure that they that they need to sleep development occurs while the child's asleep but some."

" Would make the observation that many babies come into a household where there's already one -- two -- thanks to wonder drugs maybe six other kids. They're older and that are making a racket around the house. Isn't enforcing very important also for a baby to kind of get accustomed to that buzz and that -- Illinois --"

" You're talking about the child getting accustomed but the baby is still a baby we're talking about a newborn infants we're talking about an infant from. Zero to six or seven months today. When you putting a child to sleep. It's generally better to have a quieter environment for that child that's where they call them lullabies. Right that's a very good word. Is also something else I think what it also says in terms of the environment of the house out. That the parent that understands the child needs some quietly and child's very young will also understand that for that child's mental and physical development. Fit there will be times when quiet will help that child to study to learn to read. Quiet is not silenced. It's just quiet we can still hear the breeze we can still hear -- And that the child will get and of course want those sounds those wonderful sounds. But whether it's just an infant that we're talking about we're really focusing on rest and that is definitely aided."

" I -- Arlene thank you for those insights. I now as part of doing this to the environment Owens Corning has come up with a whole concept of the Quietzone. And Harry alter was here just a few days ago getting started with some of the measures that we're taking to assure that the nursery is a Quietzone. "

" First of all the first thing to have is long sleeve shirts all right after that. You have gloves and he will handle the fiberglass lid. Next is goggles."

" I had."

" And then last of all you -- dust mask. Consists of pretty simple process. -- this type of that not enough. To put into the cabinet in Tuscany and as you know. -- all of that comes out of the face fancy have a little flange shared. We basically staple that about every eight inches. Do you just want basically let it. -- in the cavity."

" Make sure it's and then when you get -- outlet. -- basically. -- basically kind of mark where the outlet is."

" that you can take this off. And cut it out. Okay. And -- about can't. Around the outlets. Again making sure they -- not compressing the -- clean illusion just a split the the mat. Can you can stuff this. Right behind the wiring. And bring it down. All right so you've got to the wiring him and a half. When you bring the Batt up over."

" So Harry the thing I noticed right away is that you've done a very careful and meticulous job of installing. The product here. So there aren't any gaps and it did really fills in the cavity between the studs that's important I guess right yeah make sure although there's this threat cavities are filled. And then after you do that obviously -- you want to start looking for any gaps and cracks in the wall because that's an easy path for noise to get through OK and that's who we certainly can't caulk. Is this fiber that's different from what we put the sidewalk keep the cold out. Well there's a lot of different densities of fiberglass night and this is one density that is a lightweight density. And it's designed specifically for acoustics it's not used -- is not tested normally we do all our testing specifically for its ability to reduce noise. In floors or ceilings to reduce noise transmission okay so what's the caulking gun for. That quite some acoustic ceiling and this is a that's disorganized acrylic. And is designed to be flexible over time that it doesn't Harden. And we use it to seal up today the gaps and cracks in the wall. That can happen at the base plate where the base plate meets the floor and also -- around media outlets now happen after the gypsum goes up. And for this instant I'm going to be sealing up the gap where the existing ceiling meets this top plate. Just make sure everything is sealed up so all the way across from that corner and then down to the bottom. You want to provide a veto this yes. Okay. Thanks -- thank you."
