First of all, seal ALL air leaks. You can start by picking up a case of latex caulk and sealing 2xs to floors and so on. Spray foam big holes.

When you’re happy with your air leak thing, layer in some rock against the bottom of the floor. The more layers the merrier. It absorbs vibration, which kills sound.

Sound is just refractions and compressions of air waves. Stop those and you stop sound.

I did these things to a kitchen and, even before the insulation was in or the rock was on, I couldn’t hear a significant storm taking place outside.

Spend some time on Home Theater forums there is more DIY sound proofing info on those forums than you will ever care to read.

+1 for Kelly’s rock wool suggestion. You’re gonna need allot of it.

Is the ceiling currently drywalled? If not, what Ripper mentioned, the rock wool sound insulation, works great (though not perfect). Keep in mind that sound will get through, no matter what, but there are a few things (like the aforementioned insulation) that you can do to significantly reduce it. Another option is to add a second layer of drywall to the ceiling/walls, with an adhesive designed for sound reduction in between.

And Huxley is right, theater forums (and home studio forums) have tons of great advice on the topic. Used to study music tech and geeked out for hours reading this stuff when I was still recording.

While sealing air leaks is a big part of sound proofing, it’s just a part of it. The sound will vibrate the garage walls and ceiling. Since these are attached to the rest of your house, the noise will be carried to other parts of your house.

For true sound proofing, you need to physically isolate the ceiling and walls. This is the room within a room concept. This I suspect is more than you want to do.

How much the sound can vibrate the walls and ceiling is a function of how massive these walls and ceiling are. So increasing the mass can be helpful. For example, a double layer of sheet rock.

In any case, lots’ of DIY info on soundproofing on the web. I’d study this and see if there is a tiered approach you can take. One where you can do something, and if that’s good enough your done. If not, you do the next things. This might allow you to solve the problem with minimal investment.

However, you are not going to make major differences with just a few hundred $$$. Effective sound proofing is not cheap.

By the way, once your baby comes, you’re not going to have nearly as much time as you think to work in the shop. If this is your first, if you’re like most, you have no idea how much your life is about to change. Hopefully you’ll find it a good kind of change, but change it will be. And hobbies tend to go to the bottom of the pile.

Congratulations on coming event!!!

My local HD sells (or at least used to sell) a product called quietrock (https://www.quietrock.com/) that is 2 layers of thin sheetrock with a sound isolating material sandwiched in between that is supposedly pretty good for sound proofing.

The other way to go is to let the baby get used to loud sounds. When my wife and I had our first child we tried to make as much noise as possible around her. Run the vacuum, turn the tv up, run the dishwasher and disposal, anything you would normally hear during the day or night. Your baby will learn to sleep through it.

Both of my kids sleep directly over my shop and sleep just fine.

YMMV

Congrats on new baby!

This is the best solution – the room within a room concept. I actually did this in my basement, when I needed a study room for graduate school.

It is doable and reasonable because it won’t be structural. Build a completely freestanding room with 2×4 stud walls & joists, install unfaced fiberglass sound insulation, and add wall covering. For more sound control and real comfort, I’d install interlocking 1/2” polyurethane mats on the floor

This is an isolation clip used for metal studs. They can be used on wood framing as well. Installing these along with the DWC over exisiting drywall (or directly to to the framing), then hanging two layers of 5/8 drywall,will dramatically reduce noise transfer. Sound insulation is a must if the framing is exposed. This may be a more expensive option, but it is an option.
Also, if you have tall enough ceilings, an acoustical ceiling grid system hung from a similar sound isolation clip product would make a big difference.
There is alot of methods to isolate the sound to the garage. Pick one and run with it. Good luck.
Congrats by the way.

I’m not sure of the age of the house, but if it is under 30 years old I can only assume it’s double layer 5/8 drywall (fire code), and batt insulation (for warmth). I would start with a layer of Fiberboard Sheathing followed by The DWC Isolaters, then another layer of 5/8” drywall. The fiber board will dampen the sound and the air gap made by the DWC is going help the most. That being said you don’t have to be silent for your kid to sleep. when a newborn reaches like 3 weeks its time to start sleep training them. My kids won’t sleep if the house is quiet. I still remember my oldest sleeping in her high chair at the table 8’ away from me while I was banging out the windows in the dinning room. she slept through the entire thing sawzall, compressor and all.

Speaking as a dad whose son is 4 1/2 and has a daughter who just turned 1, I laughed so f*ing hard when I read this. You must also be or have been a dad, because truer words could not have been said.

Good luck OP with getting your shop time nightly, but you’ll be busy trying to grab as much sleep as you can for the first 6 months of your tiny humans existence.

Congrats on the little person! They are amazing to behold and grow up super quick, seems like only the other day my son was a little blob drooling all over the place, now he’s running everywhere and farting every 10 seconds because he finds it hilarious to gross out his mom.

+1 on this suggestion. My wife and I did the same thing after spending a week with our friends on the West Coast that had their new baby. We spent the whole time during naps and every hour after the baby’s 6:00 p.m. bedtime whispering and walking around in our stocking feet. What a PITA. My wife was pregnant a the time and we agreed that we were not going to follow her friend’s lead on that score.

When our twins were born we had them nap right in the middle of all our activities and, while we didn’t throw wild parties at night, made no concerted effort to “be quiet while the babies are sleeping”. They’ve never had any trouble adjusting to our lifestyles happening around them and I think my wife and I are better for it.

Another thing to consider is that the most difficult sounds to stifle, if I’m not mistaken, are low frequency sounds. I’d have to assume that most power tools operate at frequencies that are higher up in the spectrum and therefore may be easier to cope with when trying to eliminate sounds from penetrating the upper floors of your house.

My shop is in my basement and I have three boys under 6 and a baby girl coming in 5 weeks. I use mostly handfuls so sound isn’t as much of a concern but I wanted to make sure I wasn’t keeping anyone awake. Banging out mortises and even sawing can still be loud when its inside the house. I filled the walls and ceiling with regular fibreglass insulation and used resilient channel on the ceiling before hanging the drywall. Seems to be doing a pretty good job. Just finishing the mudding and taping so there is no door yet but the room seems to absorb sound a lot better than the other rooms in the basement.

My advice -
Don’t bother to sound proof. Keeping a baby/child in a sound proof environment is not good or healthy. They need to be tolerant of sound when they sleep. Having total quiet is actually very unsettling and makes a child nervous. Remember, while the baby is in the womb, it hears and feels a lot of sound – all day and all night. It hears and feels outside noises as well as inside noises so when that goes away, it loses reference that it had – kind of like you going out in the middle of winter to a sealed cabin with nothing (including light) except sound deadening earmuffs – no food, clothes, or heat. That is what it feels – no nice warm environment, no continuous food, and now you want to take away sound. All it has (and it didn’t have before) is smell and taste, which they don’t understand yet.

As for actual time in the shop – you are only going to make what Mommy needs for the “right now” events for about 3 years.

If you want to do something actually fascinating, watch your kid and how it learns. Everyday your child is learning something – hearing, observing, watching, touching, tasting – it is so remarkable to watch. Don’t “baby” talk to it but when you speak to it – face it and show it how to you move your mouth when you speak, it will learn by both listening and watching.

Its funny, you spent the first 2 years teaching your kid to walk and talk and the rest of your life you tell them to sit down and shut up!

Well, after seeing all of the other comments, thought I’d chime in yet again.

I, too, have small children (5 1/2, 4 and 2), and all of their bedrooms are directly above my garage where I keep my shop. When the oldest was a baby, we lived in an apartment near the train tracks, so he got used to the noise. The other two adjusted based on the volume of their siblings and household appliances.

Even when my two year old is napping, I can go into the garage and run my miter saw (obviously, one of the louder tools) and shop vac with no real concern of waking him up. The only thing I could think that would compete with that combined noise would be a planer, but he’s fine otherwise. After all, kids seem to sleep based purely on a whim, and not really based on our needs or anything we try to do for them!

Not just a dad, but a stay at home dad who had visions of putting the squirt down for long naps and making strategic cuts and quiet work in the shop throughout the day and in the evenings…. Not reality.

Didn’t get back in the shop until about six months ago. Little dude is almost three and we are learning how to wear ear protection and to avoid randomly pushing buttons. He really likes my maple mallets the havoc they cause – and he’s figuring out that saw dust is not as fun to play in as he thinks.

So yeah, there’s hope, but you can just let all that go for the first two years.
