It doesn’t matter if you’re a recreational DIYer or a serious garage guru, you make noise. It can’t be helped, especially with power tools. And if you’ve got close neighbors, you probably always think about that noise when you’re switching on a machine. Soundproofing your garage/workshop is the key to maximizing your freedom. Imagine being able to cut lumber anytime–late night or early morning– without fear of wrath or reciprocity.
There are, of course, a number of methods to soundproof. For the “whatever” DIY guy, it might be hanging moving blankets on the walls and ceiling. There’s another method called “resilient channel” which is what a lot of the nicer recording studios use, and which is great… if you’re building a nice recording studio. An approach I like a lot more is the “cleat” method, suggested by “Mobile Rik” on Instructables.com. With a lot of easy-to-follow steps and lots of pics, Rik shows us how hanging drywall panels on a pair (or more) of wooden “cleats” can contain a great deal of sound. Compared to the “resilient method, the “cleat method is:
- Much cheaper
- Much sturdier (if you decide you want shelves or other heavy things hanging from those walls)
- Is removable for tweaking if necessary
- Uses ordinary 2 x 4 lumber and not some fancy-shmantzy materials that need to be special-ordered
But, be warned, the “cleat” style is based on different– even contrary– principles to conventional soundproofing methods. But this is the cornerstone of every blue-blooded DIYer: Build A Better Mousetrap! Be sure you read Rik’s “Be Willing To Break The Rules” section to understand the high-fidelity physics behind his approach and why he’s going this route.
Take a look at Mobile Rik’s “How-To” and see if this is something you could do in your garage!
But first, here’s a quick (short) list of what you’re gonna need:
- Table Saw or Band Saw (must have miter capability)*
- Tape Measure
- Staple Gun
- Utility Knife
- C-Clamp (at least 6″)
- Screw Gun
- Caulking Gun
- Flat Pry Bar (optional: to help lifting drywall off the floor)
*If you don’t have a table saw or band saw (although this is as good an excuse as any to get one), you could skip this tool by going to the lumber store and have them rip your boards per your specifications.
- 2-1/2″ Nails
- Drywall Screws
- Closed-Cell Foam Tape
- Polyethylene Pipe Insulation Tube
- Drywall 1/2″ (you may even consider 5/8″; besides killing even more sound, it’ll add fire protection and be more gouge-proof)
- Acoustical Caulk
Other Tips To Deaden Sound In The Garage:
- Buy a pack of rubber washers and apply them to machine cabinet fasteners as long as it’s not a critical connection for precision alignment
- Retrofit all of your tool stands to include rubber-wheeled casters, and look at using rubber grommets on the plate holes where you bolt them to the stand legs
- Buy those square rubber vibration isolation blocks and use them to separate the tool from the mobile base or tool cart
- Spray sound-dampening material on the insides of metal machine cabinets
- Add sound insulation lining to machine cabinets, router table chambers
- Use baffle-like sound shields made of sound-absorptive materials near motors and other noise sources without restricting heat dissipation for the motor.
- Add additional sound absorbing material (perhaps backed by sound reflecting material) directly behind noisy machines that are against the wall
- Safety guards around blades and bits do help with both dust collection and noise isolation, so it’s not a bad idea to use them when you can, especially over the table saw blade. Maybe make your own, and incorporate some sound-deadening strategies in addition to dust collection efficiency strategies.
Remember that a lot of little things will add up to a much quieter shop. You’ll feel much more free knowing that you won’t get complaints about your late night or early morning dust-making activities. And remember Harbor Freight Tools when you need a quality tool at a very low price!
