Rockwool OR Fiberglass for DIY sound panels?

DIY

sound

panels

have been very popular over the last year since people set up music studios at home. I've received a lot of comments asking me which

sound

insulation material is the best and how I built my

panels

, so in this video we are going to test and compare four types of sound insulation, rock wool,

fiberglass

, acoustic foam and denim. Before moving on to testing, it is very important to make the distinction between sounds like music and speech and noise. Acoustic engineering is an advanced branch of engineering that analyzes how sound behaves in a space and how sound waves bounce off walls, flows and ceiling sound or acoustic treatment is an art, whether in a music studio , concert hall or in a cinema, remember that there are scientific principles behind the placement of the panels and their shape or their thickness these DIY panels that we build are noise absorbers, not sound panels, technically they are mainly insulating materials for buildings , its noise damping properties are secondary characteristics, dampen the mid and high frequencies and harmonics of music and voice with over-absorption to test insulating materials.

I bought this vlca digital sound level meter on Amazon for $56. I'll link it in the description below for consistency. We're going to test three inches of insulation, then the noise emitter, and then another three inches of insulation. Apologies in advance for the inconvenience. high pitched noise that we are going to use to test insulating materials measures around 77.3 decibels first we are going to test denim or cotton insulation this is a very dense product and is actually used to make acoustic panels it costs one dollar and fourteen cents per square foot at Home Depot, two layers or three inches of denim reduced the noise to 75.5 decibels, another three inches reduced it to 72 decibels, which is a drop of 5.3 decibels.

Rockwell Safe and Sound is out of stock at my local Home Depot and Lowe's, so I purchased some thermofiber slag wool insulation that has very similar acoustic properties to Rockwell. It costs 94 cents per square foot sandwiched between two three-inch layers of rock wool. The noise level dropped to 69 decibels, which is a difference of 8.3 decibels before testing the

fiberglass

. and acoustic foam I need to tell you that this is my first sponsored video. This part of the video is brought to you by Insulationforus.com. Insulation for us is the largest US online retailer of insulation products and ships nationwide with over 800 locations. to ship through their extensive distribution network, they are cheaper than big box retailers and offer a flat shipping rate of $60 on 80 of all their products.

Next, we're going to try these 12 x 12 inch acoustic foam panels I bought. amazon they arrive vacuum sealed and slowly expand in a couple of days they cost 1.50 per square foot and are very easy to install they reduced the noise level to only 73.3 decibels a difference of four decibels lastly fiberglass , the biggest surprise was that I bought a roll of 2x4 walls at Home Depot for 50 cents per square foot sandwiched between just two layers, the sound level dropped to 65 decibels, a difference of 12.3 decibels, the fiberglass was , by far the winner, was the cheapest and had the best sound deadening qualities, this test was really amazing to me because everyone talks about the performance of rock wool acoustic panels and that's why I built my panels with them, but I could have cut the cost in half by simply using fiberglass.

There are obvious risks to both materials. I always wear eye protection and a mask. and long sleeves because I'm bothered by red bumps if it touches my skin, but once both materials are wrapped in fabric, their risks are minimized. My sound panels measure 31 inches by 48 and a half inches and are made from 1 by 4. I painted the posts when they were reasonably priced. I cut the posts into two 47-inch pieces and two 31-inch pieces. The middle stand is 29.5 inches long. The four angled corner supports are eight inches long. I used glue and a nail gun to assemble the frame. and then I smoothed it out with an orbital sander.

Two pieces of rock wool insulation friction fit into the frame quite easily. I bought some felt fabric at joanns and attached it to the studs with the crown stapler. I hope you found this video useful for both the material and the material. use and for the panel construction method, this was obviously a very unscientific way of testing performance, but I think it was effective.
