Regular fiberglas insulation isn't probably the best soundproofing material, but, it you don't have to make the shop perfectly sound proof, it has worked well for me. My shop is on the other end of the housed from the bedrooms and in the basement. I have soundproofed the ceiling with fiberglas insulation and the walls between the shop and the rest of the basement with drywall, fiberglas insulation and, on the other side (which is a family room), drywall with an outside layer of sound board. Between the rooms, very little sound comes through. Upward, more comes through, but I rarely worked when my kids and wife were asleep. Now, that the kids are out of the house, and I am retiriing soon, I may work at night more. It could be a problem, but the point is that, if you don't have to block all sound, fiberglas insulation can work.

On of the most important lessons I learned about soundproofing doing Home Theater work (Home Theatre for those of you who prefer metric [wink]) was that MASS stops vibration.

As mentioned before, the cheapest solution for most shop applications would be to add a second layer of sheetrock on top of the first.

If you're starting from scratch, consider using only 5/8" because of it's extra mass. Install the first layer. Tape and mud all the joints like normal. Although the finish doesn't have to be PERFECT, it has to be COMPLETE - no holes or gaps or weak spots for sound to get through.

Install the second layer, alternating the seams and joints. Try not to let ANY joints or seams line up except where you can't avoid it, like in the corners. Even there you can minimize the possibility of 'bleed through' by carefully installing the top layer opposite of the first layer - i.e. if the first layer had the left piece going all the way to the stud(wall) and the right piece butting up against it, make the top layer have the RIGHT piece go all the way to the wall/stud and the LEFT piece butting up against it.

Doing this requires a little care and planning, but it adds almost NO COST if you're doing it yourself, and it WILL pay off in major sound transmission reduction!

My workshop is built from 4x2 timber studs, external shiplap cladding ( no ply/ sheathing) Insulated with 4 inch kingspan foam. 1/2" plasterboard - plastered. The floor is 6x2 timbers with 3/4" ply glued/screwed to the timbers.
4" fibreglass insulation in the ceiling and same treatment as the internal walls.
I have run my benchtop thicknesser, extractor ( vacuum type) and router table all running at the same time, and to hear that lot i need to be within 10ft of the workshop. :)

in such a situation , best solution is to have a temporary sound proof wall, but for effective sound proof it is better to go for layer by layer tempory wall, or curtain for example, i recomment to go through this article…/und-Barrier-Insulation.html and…/f-Fencing-Introduction.html
look how 4 layer sound reduction is used to make a sound proof fence. and better part is its easy to remove and transport. i hope it is helpful for all

I sure someone has posted the wall system that I use, but here goes. Double 2x4 walls with spaced upper and lower plates, with the second upper plate tying the walls together. F.G. sound batts and drywall on sound channels. I have used it for years and found it to be the most cost effective system. B

Mineral or Rock wool is the insulation you want for sound attenuation.

Fiberglass is really only a feel good solution.
