jonoyakker on Noisy neighbor! Sound Barrier Technology Hello and thanks in advance for your help. I have a close, noisy neighbor (speech and banging doors) They are rather inconsiderate and my requests to reduce the noise have not been sufficient.

Would a wall on the property line that is constructed of metal roofing help much?

tmessina on Lead sheet, lead plywood, lead sheetrock Sound Barrier Technology I would like to start a discussion of using sheets of lead, lead plywood, and/or lead sheetrock as acoustic treatment tools. If anyone has any thoughts or information could you please add them to this topic.

Dennis Foley on Layering 5/8" sheetrock over 5/8" OSB ?? Sound Barrier Technology E, Neither method will be sufficient. You must use methodology that is a full range covering frequencies from 30 Hz. - 20,000 Hz.

engineerjoel on Layering 5/8" sheetrock over 5/8" OSB ?? Sound Barrier Technology Building a wall Separating a Control Room with Live Track Room: Would layering two different types of material such as sheetrock and OSB would help reject/block/isolate (or whatever you want to call it) sound more efficiently than layering two layers of 5/8" sheetrock???

please advise.

jazmario98 on Treatment to dampen sound inside of a closet Sound Barrier Technology Hi, I found you on YouTube while researching soundproofing. Your videos
are incredibly helpful! I'm an absolute beginner so apology for all the gaps in my knowledge, but I'm just seeking advice on the following project.

My project - Silly as it sounds, I'm just trying to turn my closet (image link at the end of the post) into an area where I can practice my singing (my roommates and I have opposite work schedules so I'm often practicing when they're sleeping. I don't have a car to practice in and renting practice space isn't an option right now). My goal is to dampen the amount of sound my roommates AND the apartment below me can hear as much as possible, knowing full well that "soundproofing" to any degree is completely unrealistic without constructing a separate structure within the closet. So again, reducing the amount of sound they can hear is my only goal. I'm on a budget and trying to spend less than $350 if at all possible...luckily I'm on the top floor so I don't need to worry about sound traveling upwards.

After hours of DIY research, the initial plan I came up with was: 1) create rockwool panels by encasing rockwool in chicken wire and then encasing the panel in a sleeping bag, and hanging one of those on every wall in my closet 2) covering the walls with panels of MLV vinyl using a staple gun, going over the rockwool panels, and then 3) making a lame attempt at a floating floor by laying down another layer of MLV vinyl on the floor, stacking some neoprene rubber blocks and then overlaying that with some drywall to form my "floor." Another guy even recommended a layer of tennis balls cut in half instead of the rubber blocks.

However, after watching your videos
I don't want to go anywhere near rockwool. So I feel back at the starting line. So my question remains - if I want to reduce the sound as much as possible that others can hear when I'm singing in this closet, with the sliding mirror door closed, what treatments or materials would you recommend (staying hopefully under $350)? And furthermore, though I'm afraid to ask, can I even achieve any meaningful sound dampening via DIY methods on this budget, or is this a waste of effort? Some other hacks I was going to try was buying soundproofing window treatments for home theaters and hanging those, but those are around $400 each and I'd need 4 of them.

Thanks in advance for your advice. Really appreciate all the knowledge you're spreading via your channel.

Taewon Kim on which ppi of Carbon(Graphite) Foam do i need to buy ? Sound Barrier Technology I bought and Read "All In One

But there is no mention about Carbon Foam ppi.

which ppi of Carbon(Graphite) Foam do i need to buy ?

Dennis Foley on Building my recording booth inside my room Sound Barrier Technology D, No, MLV will not work for dog barks. You must measure the noise and design the proper barrier technology to deal with the frequency and amplitude of the noise. Guessing with noise is a losing proposition.

dlopezm on Building my recording booth inside my room Sound Barrier Technology I’m building a recording booth inside my room. Right now the structure is ready (made with pine board). I have hanged acoustic blankets in the internal part of the structure. This is part of the process and how it is looking right now.

View post on

I would like to wrap it completely (including the top and bottom part) with an outer layer of Mass Loaded Vinyl, with a density of 1 lb / square feet.

I want to reduce the barking sounds coming into my room. which are in several frequencies, some low frequency barks from bigger dogs and some higher frequencies coming from smaller dogs.

The dogs are from the neighbors, each one in their own house, but my room has a big window in one of the walls.

Would the mass loaded vinyl have a significant impact in reducing this noise?

Dennis Foley on MLV double layer with or without gap? Sound Barrier Technology L, I do not know what "loud neighbors" means. You must measure the frequency and amplitude of the noise and then build the appropriate barrier.

LimpMass on MLV double layer with or without gap? Sound Barrier Technology Hi, I've got some loud neighbors. I'm looking to help reduce the noise bleed coming through the walls. If I'm to deploy two layers of MLV, would it be better to stack them directly on top of each other, or would it be better to mount one layer of MLV, then have an air pocket, then MLV again?

From the (great) video series acoustic fields provides, I'm lead to believe that I want the greater mass, therefore the first option, right? I'm primarily looking to decrease the bass frequencies and will also deploy a double layer thick drywall to help reduce upper frequencies.

Thanks in advance for your suggestions!

Skogs on Wall density vs room modes Sound Barrier Technology Hi. I have a dedicated music listening room
in the attic. It is difficult to get good coverage of fullrange acoustic treatment, because almost the entire ceiling is slanted. Currently the slanted ceiling consists of multiple layers, and a total thickness of about 4cm. I currently have big issues originating from around 30-40hz.

The current ceiling have to be changed for other reasons, so i am free to choose what the new ceiling will consist of. If i use much thinner material for the ceiling, like one layer of 10mm mdf, will those low frequencies simply pass through instead of bounce around inside the room?
