Sound Rating a Wall
Step 1 – Putty Pads
Before the sound insulation goes in the wall, all the outlets need to be covered with the sound putty pads. Let’s get started! BTW, I did use disposable rubber gloves to handle the pads. There is an oily base to them and will leave your hands greasy.

Starting with a basic box, it was an exercise in origami to cut the corners of the pad with scissors and fold it over, around, under and between the cables and box to look like…
404
This! Pushed it tight to the stud and the drywall and on to the next box!
405
Even the boxes on the face of the wall also need to get covered.
407
And each and every hole going through the wall also gets sealed.
408
Once the Putty Pads are in place, we move on to..
Step 2 – Sound Insulation
I found the local source for the Roxul Safe’N’Sound Mineral Fiber was our local Tibbetts lumber yard. So, I didn’t have to special order from Lowes, which was my second option. I figured I should need three bundles of insulation, so I borrowed a friend’s pick-up to get it. Since I had the truck , I bought the drywall at the same time.

The insulation for 2x4 walls comes in strips 47” long by 15-1/4” wide by 3-1/2” thick. Many of the strips can be installed straight into the wall. But when it needs to be cut, I found the easiest is an old serrated knife that I confiscated years ago for use in the garage and landscaping (its great on banana trees as well)
Just measure out..
409
…and cut until it cuts through. By The Way… I used disposable gloves when handling the insulation just to prevent any fiber issues. It’s not fiberglass, but it is insulation!
410
Very easy to cut!
411
The most time consuming part was measuring all the different size panels that were needed. A couple studs were less than 16” on center and so I had to take a couple inches off the length.
412
Even had to cut notches out and tuck in behind all the braces and receptacles.
413
A little persistence and it was complete. I think this took several evenings to complete. Not a half-hour job!
414
Step 3 – Acoustiblok (Mass Loaded Vinyl)
I picked up the Acoustiblok at their factory in South Tampa. My calculations were that I would need about 2-1/2 of their 30’ rolls. They have 60’ or 350’ rolls as well, but the small roll was already close to 150 pounds each. And I had to get them out of the car and into the garage by myself! These were heavy!
415
Before I could hang the vinyl on the wall, I had a couple places where I needed to work on. The speaker cables were not in boxes, but had mud rings installed for a drywall opening. That means that there would be a hole in the Acoustiblok if I didn’t do something. So, I added a piece of vinyl behind the opening and tucked it deep down the stud.
416
I made sure the cable was accessible and then screwed the vinyl to the stud above and below.
417
One Saturday, a coworker (retired contractor) came over helped put up the Acoustiblok and the drywall. I guess we were working so fast that I didn’t get any pictures of the install process. It took both of us to hold the vinyl in place to get the nails started. One piece to install was 55 pounds (25kg) and we had to hold in one hand and hold a roofing nail in the other hand and use a hammer in the third hand to hit the nail. I don’t know how we did it, but we got it hanging. Then each seam was caulked and then sealed with a tape made specifically for vinyl.
418
Step 4 – Drywall
He knew what he was doing, took all the measurements, went out in the garage and came back with a piece for me to screw in place.
419
Then taping and mudding!
420
And more taping and mudding, sanding, mudding, sanding…
421
Lots of sanding until Mrs. Wingnut convinced me that the wall behind the entertainment center does not need to be painted. So I stopped sanding cleaned everything up and had a cold one!
