Soundproofing/Acoustic Walls | Underground Earthbag Building |

 Bree: In the previous episode, we finishedthe frame for the ground floor in the earth bag underground MusArt Studio. We were planning to do the natural light andvenilation video this week but we have had so many wonderful ideas from you, we needtime to process and think about it. So, instead,, let's go ahead and check inwith Dad as he works on the bannister. Gary: What's good about a post that is secureis if you can actually make it part of the floor. Bryson: With the bolts in, we can so we canbolt it down. Gary: You may remember how we cut down thetree limb. 

We used a lot of that cut down and branchesand stuff. That's what's cool about mesquite it is reallytwisty and fun. Bryson: It's not like plywood. Straight. Gary: We bolted it right to the 2x10's. We are going to run that at 38 inches on thepost height and then we will probably come down another inch with the ability to wrapthe hand rail, the bannister rail that is going to go around. Maybe like 40 for the top section after weget the railing piece on. And then bag right up against it and thenput some blocks in. So, that make really nice strong post as apposedto attaching it with a bracket or something to the top of the deck. That's hard. Shelly: Now what are you going to do? (Music) Shelly: Yea. Come on. Good boy. Max: RoofBryson: Now that the main post are in, we are going to head down stairs. The first thing that we need to do is to getthe wiring in. 

Laying down some electrical? Gary: Yup. Doing the 3 way switch so we can turn thelights on and off upstairs...and the fan too. Bryson: And the bottom switch becomes themain switch for the lights. So, right now we are running the track lighting. We need to get the wiring done so that wecan get the walls on and the ceiling. Shelly: So, we are doing wall prep.not a lotof wall prep though right guys? Just a little bit? Shae/Bree: Mostly the big holes. Bree: What you are seeing is the aftermath. I was carrying this on my shoulder and rightwhen it got on my shoulder...boop...It fell right here. Bryson: we have modified this to run con throughbut now we are going to run mud back through it, So, It is going to be the mixed perlightmud so, it will act a lot like our normal mud we run through it. 

A little more watery than that... Shelly: Ok. So the plan the guys are doing... Gary: Is to mix the mud with the perlight. Which is a textured surface that we can actuallyput right into the mud and it will create a texture for us. Very similar to a textured ceiling would bein the old days. Bryson: One to one for right now. Got to see what comes out. We are going to add some water...just a littlebit I would imagine. Alright. should we go test it? Ok Dad, let's pour some in. ready? Gary: It might be a little... Bryson, It's a little too thick. Yea stop. Gary: We started out with a ratio of one toone. Equal amount of mud to perlight. So, then we add water. till we got it to peanut butter. We made sure that was our first one. 

Then I went to pancake batter. I wanted it a little bit thinner. Bryson: What do you think of that? Gary: Bryson,Bryson: It sure is texture. I wouldn't worry about those strings ma. wewill go right over the top of them. Gary: That is soft. more? this is yours. I got to make more. I came up with the idea because I know soundmoves in a straight line. Sometimes it's omni and it goes in all directions,but usually it moves in one direction until it hits something.And the more times it hitssomething, the weaker the signal gets, the weaker the sounds gets. So. the idea was it that with the rolls ofthe bags you het a little bit of deadening.the sound hits that and rolls in and disappears. And it also too, reflects off the little piecesof perlight. That will also send it someplace else andit bounces off something else. and it starts bouncing. The more bouncing we can get in there, isbetter. The flatter the walls are it just bouncesback and forth. But if I can get all kinds of different anglesand soft materials and that causes the sound to deaden. and that is what we are tryingto get. It sounds good when you are standing in themiddle. 

And when you move over here it is a lot quieter. Over here. A Parabolic shape, half of a circle, worksjust like dish or receiving signals. It draws that into one space. The middle of the room is probably going toget the most sound coming to it. The further you get to the edge, out to thewall space, it will be less. When we start capturing sound in there thebest place will be on the outside of the room as opposed to the middle. Testing 123 testing 123. The acoustics have already changed by thetime we sprayed on the that little bit right there.This is the testing spot right here. it is going back and forth. Bree: We could mud right here and retexturelater. Ok... What this perlight does according to dad,i learned 5 minutes ago is...it makes it kind of light and frothy, it gives it some air. Bryson, what is it used for? Bryson: It is a dampening sound. the mud and the perlight help dampen the sound. Bree: My Little Homestead theory. Bryson: Are we going to paint this too? Gary: Ya. It get some paint too. Shelly: There is   a lot of paint though. Gary: We may need another box of mud. Shelly: Nice hole Bry... Bryson: It made this hole...we were loadingit and made this hole. But it is a mess. next time we open the bag, it doesn't openby its self. Isn't this perlight for gardening? Gary: Yes. Bryson: You know those plants we get in ourwall all the time? Gary: Hey Ya. we could grow trees on the wall. Bryson: Well I mean. do you think they will be coming up a lot? Gary: No. Bryson: Somebody added too much water. Gary: 

Almost like pancake batter rather thanpeanut butter. The test. Pancake Batter. Bryson: No. Shelly: No? Bryson: I was thinking of something else. I guess... Shelly: You were on a different subject? Bryson: I was:Gary: You were thinking of food. I said Pancake. Ohhh Dinner time. Bryson: I was thinking of food. Bree: Stay tuned for next time as we continuebuilding on the MusArt Studio.Thanks for watching. and Have a great week. All: Thank-You! Shae: Please consider supporting us on Patreon. [Goat Sound]Shelly: You just slow down... Bree: We were planning to do the natural..Slowdown and remember and remember to slow down and remember your lines. It's my curse...Just kidding. Shae: Our family moved from the city to thecountry. Thanks for taking part in our adventure. We have new videos every Friday evening. If you’d like to help us out, you can likethis video, share it, subscribe or support us on Patreon. See the links in the description. Bryson: hey Mike. I think you gotta a little blooper on you. Gary: I think she wants a little more.theelectoral stuff. Bryson: you are getting pants all dirty withyour shoe like that. Gary:We installed...(Kachint) Bryson: Dang it. Gary: Sorry: (Kachint) UmmmmBryson: Stop it. Gary: Are you ready now? Here we go. Stop waisting film. Oh...it's not film. Waisting space. We are going to call it sheet rock mud perlightpancakes for you Bud. It didn't taste like pancakes though. Bryson: It tasted like calciumGary: Sheetrock mud. Sheetrock, water and Filler. Bryson: Sheetrock mud....

How to Soundproof a Room : DIY Soundproofing

Hi, I'm Arthur Noxon, president of AcousticSciences. I'm going to talk today about do it yourself soundproofing. Now this is- thecontext for this is in a recording studio. Okay, sound proofing; number 1, sheet rockacross the windows, two layers of sheet rock across the windows, you can push them in thewindow well, cut them just to the right size, push them in the window well. 
If you wantto make a little trickier, a more repeatable window plug, take a piece of sheet rock, gluea piece of sound board, which is sometimes known as celotex, fiberboard, to it, and thensheet rock. The soundboard is larger, here's the soundboard, the sheet rock is smallerhere, and another layer of sheet rock here, everything is glued together with panel adhesive.This is sort of like a sliding gasket, these two layers of sheet rock are like your soundbarrier, and this is your sound isolator between the two. 
This is sized so that it pushes intothe frame of the window well, that's the window here…

How to make acoustic foam

Hey guys welcome back to another blender 2.8tutorial and today I'm going to be showing you how to make acoustic foam all inside blender. So acoustic foam as you know is this sound-proofingon walls which kind of looks like spiky foam, is what we're aiming for. So we're going to start off with modeling,so this tutorial is going to cover modeling, shading, and also a bit of uv unwrapping. So starting off with modeling we want to selecteverything a, x, delete. So we got rid of everything. Keyboard shortcuts up here by the way. So we got rid of the default cube just sowe can add it back in. That's what the professionals do apparently. So shift a, mesh, cube. So efficient. Ok so now that we have this cube, we wantto flatten it down. So s for scale and then z. And then we'll do something like 10% so .1. And now what we want to do is add some spikescoming out of this. So easiest way to add spikes, tab for editmode, control r for adding some loop cuts, and then we're j…

How to Soundproof Windows in Your Studio

Are you looking to keep sound out of yourhome recording studio? Like if you have a noisy neighbor that youdon’t want to pick up at your recordings, or maybe you need to keep the sound insidethe room, like if you’re practicing your new drumset. In this video, I’m gonna share how I solvedthe problem of sound coming through the windows of my home video studio. Of course, this solution only works if you’reokay no longer looking out the window. 
So if you need your windows to still be openand have light coming through, there’s another option. I’ll put a link in the description. I have a friend who did this. He’s got a music studio and he needed toleave his windows open. And essentially what it is is a press-in frame. It’s custom made for every window and itgives you another layer of thick material and no air cracks around the outside. It’s a little bit expensive but you cancheck that out down in the description. But today, what we’re gonna do is just blockout the window 100%. So I started …
