Hi all, I am new here and to be honest cant figure out where to plonk my question...seeing that we all use noisy tools maybe a ''workshop'' board might be good?...

Anyway, I am fortunate enough to be in debt for a 7 mtr by 16 mtr (19 ft by 52 ft) shed ready to fit out as my woodwork shop. Currently I have zero soundproofing as I live in farmland with also, zero neighbors but the new shed is closer to other homes. The nearest are about 45 and 60 mtrs (147 ft and 196 ft) from the shed i will convert into a soundproof workshop

I am already familiar with the double stud wall concept with two layers of 5/8 plasterboard each side, creating an air gap of about 10 inches or so. Also the use of either green glue or MLV between the sheets

Due to being able to construct a large shop inside the existing 1930s shed (timber frame and corrogated iron) the builder and I do have the luxury of plenty of space for thick walls and ceilings. The workshop will be 7 by 10 mtr and 3 mtr tall walls. So i already know its not going to be cheap!

Three main questions are in our minds as we are going the double wall route

1. Is it worth the outlay of extra drywall sheets to line the old shed BEFORE building the double wall stepped in from them? (it would give us three walls with an air gap between them. sort of a shame to waste the old outer walls timber frame)

2. Is the use of rubber mount methods (such as Rondo acoustic mounts) going to add any extra sound reduction to the build over the double (or triple)wall? These suckers will make the walls even wider as they float the plaster board about 4cm off the timber stud frame. I'm not sure as floating walls they will be strong enough to secure shelves and fittings to.

3. Has anyone used 70mm thick styrofoam in a ceiling and covered it with plasterboard for soundproofing?

I sincerely hope some of you guys and gals might be able help. We have digested a lot of google and youtube, but really dont answer specific variations and their cost versus effectiveness. Like the rondo clips... plenty of information on single stud walls for home theatre biy the tubes on double walls and plasterboard never seem to use them so perhaps the double (or triple) wall really makes them of not enough extra noise reduction?

We only get to do this build once and want to do it right but also dont want to thrown money at methods that will not make much better than the two walls method in the first place. I think you know what i mean!

I'm sure answers might generate more questions

cheers

Hi all, thank you for the input so far and the welcomes

I will take a router and some timber down next time we go down to the new place (90 min away) and have a listen. I do know that here from the current steel frame and iron shed that we can hear the noisier machines at 18 mtrs away(59 ft) ...The wife can hear the workshop from further away than I can...maybe the neighbors are hard of hearing?

Perhaps i am being over careful, after 10 years of no neighbors i find having them around a bit daunting and the last thing i need is the local council banging on my door.

The land is pretty flat with few trees (as of now) between homes. No thoughts on heating right now (I used to burn my offcuts in a little pot belly heater until I almost set the shop on fire and the wife banned it) but for cooling I use and will use an evaporative roof top cooler if i need it.

I need to rebuild some of the shed (roof is in bad shape) so as we aim to build one stud wall and plasterboard it for a cleaner workshop than my current one so we are figuring that we may as well do it double to make sure regarding noise control. Fortunatley the builder is my brother in law ''family rates'' and having just sold our place for the first time ever we can afford a swish purpose built workshop instead of making do.
