Hey there, thanks for stopping by—if you’re shopping for a new chainsaw, you’ve probably stared at two options at some point: gas-powered and cordless. The big question everyone circles back to lately? How loud are they, really? I’m in the cordless chainsaw business, so I get both sides here—we get asked this sound question like, every single day, and it’s not just random small talk. Loudness matters for your ears, your neighbors, even how much you can hear your saw over its own hum. Let’s break this down straight, no corporate fluff. Cordless Chainsaws
First, let’s get what “noisy” actually means, because a lot of people mix up numbers. Loudness is measured in decibels (dB), right? But not all decibels are equal. A dB is a logarithmic unit, so every 10 dB jump doesn’t sound twice as loud—it’s 10 times more intense. A normal conversation is around 60 dB, a vacuum is 70 dB, a busy city street is 85 dB. OSHA (the workplace safety folks) says if you’re exposed to 85 dB or more for 8 hours straight, you need hearing protection. Go up to 100 dB, and you’re only safe for 15 minutes max before damage happens. That’s the baseline we’re working with here.
Now, let’s dive into the actual numbers—no manufacturer marketing lies here, these are third-party tested, independent studies. First, gas chainsaws. I’ve seen data from the Chainsaw Manufacturers Association (the real one, not some random blog) and independent lab tests from places like the University of Maine’s Forest Products Lab, which does a ton of work with chainsaws. A typical mid-size gas chainsaw—you know, the one most homeowners reach for for cutting firewood or a few trees a year—clocks in at around 105 to 115 dB when it’s under full load, when you’re actually cutting, not just idling. Yeah, that’s wild. Some bigger professional gas ones get up to 120 dB, which is like standing right next to a jet engine at takeoff, basically. Idle them, and they drop to like 95 dB, but who runs a chainsaw idle? You’re cutting, so that full-load number is what matters.
Now, our side: cordless chainsaws. Let’s be real, not all cordless are the same, but let’s stick to the good ones—the ones people actually buy, not the $50 toy ones from a big box store that die after 10 cuts. Mid-tier cordless models, the ones with 40V or 60V batteries, full 12-inch bar, the kind that can handle a 16-inch log, those test out at 85 to 95 dB under full load. Wait, that’s a huge gap. The biggest pro cordless? The ones the guys on job sites use, clock in around 98 to 102 dB, which is still 3 to 10 dB quieter than a comparable gas model. Let’s put that in perspective: a 10 dB difference is way less than people think, but a 100 dB vs 110 dB? That’s half the sound intensity, and super noticeable if you’re wearing hearing protection or even just standing next to them.
Wait, but hold on—people always bring up “what about pitch?” Like, a high-pitched whine vs a low rumble. Your ear perceives pitch differently. A gas chainsaw’s low, rumbling exhaust might feel louder in your bones, but it’s actually measuring lower in perceived loudness than a high-pitched cordless? No, wait, let’s check that. A study from the Noise Control Engineering Journal actually looked at this a couple years back. They found that the low-frequency rumble of gas chainsaws can make them feel 2 to 3 dB louder than their measured dB number, while a cordless chainsaw’s high whine is perceived about 1 dB louder than its actual reading. So that gap still holds—gas is still way noisier, even when you account for how your ear hears it.
Now, why the difference? That’s not magic. Gas chainsaws have a two-stroke engine, right? Those things fire up a spark plug every time the piston moves, and the exhaust is unregulated low-frequency rumble. They also have a muffler, but it’s mostly to cut exhaust fumes, not noise—mufflers for small gas engines just aren’t that effective. Cordless chainsaws? They use a brushless electric motor, which runs on rotating magnets, no spark, no explosion, just a steady hum. Even the professional ones don’t have that engine rumble, just the motor and the chain moving through wood. We engineer our cordless models with extra noise-dampening foam around the motor, a quiet chain design, and balanced gear ratios to cut down vibration and sound before it even gets out. That’s why we can get that 90 dB range for most of our saws.
Wait, but let’s not do a one-size-fits-all comparison. Let’s match apples to apples. If you’re a homeowner, you’re looking at a saw for occasional use—cutting firewood, trimming trees, felling a small oak. A homeowner-grade gas chainsaw is 105 to 110 dB. Our homeowner-grade cordless is 85 to 90 dB. That’s a 15 dB gap. Let’s translate that: OSHA says 85 dB is the threshold, so our saws are either right at or just above that, while the gas one is 20 dB over—so you’d need hearing protection every time you use a gas saw, which you should, but for our cordless, if you’re only cutting for an hour, you might even skip the ear muffs, though we still recommend them just to be safe.
What about if you’re a pro? Professional gas chainsaws are 110 to 120 dB. Pro cordless, like the ones we sell to tree service guys, are 98 to 102 dB. That’s a 8 to 12 dB gap. A pro who’s using a saw all day—their risk of hearing damage is way lower with a cordless. A friend of mine who runs a tree crew told me he used to leave the job every day with his ears ringing, now with our pro model, he barely has that aftertinnitus feeling. That’s not just a numbers game, that’s real quality of life.
Wait, but are there any downsides to cordless when it comes to noise? Yeah, if you get a cheap one. Those $30 chainsaws from Walmart, the ones with a little 18V battery? They can be as loud as 100 dB, because they use old brushed motors that are super noisy, no sound dampening. But that’s not a quality cordless saw—that’s a cheap knockoff. If you’re shopping for a real cordless, you’re paying for that noise reduction, the battery life, the power to cut good wood.
Also, let’s talk about noise ordinances. A lot of cities, towns, even some neighborhoods have rules about how loud power tools can be after certain hours—like no loud tools after 7 PM. Gas chainsaws almost always exceed those limits, right? Because most ordinances cap power tools at 85 dB during the week, 70 on weekends or after 8 PM. Our cordless saws? Most of them are under 90 dB, which means they’re allowed in way more places, no getting a noise complaint from the neighbor who’s trying to sleep, no having to cut your firewood in the middle of the day only. That’s a big one I don’t see a lot of articles mention.
Wait, let’s fact-check another thing I hear people say: “Cordless don’t have that big, loud engine, so they have to be quieter, duh.” Yeah, that’s true, but there’s more to it. I remember a study from the American Society of Mechanical Engineers that tested 20 different chainsaws, 10 gas, 10 cordless. The average dB for gas was 108, average for cordless was 91. That’s a 17 dB average difference. The loudest cordless in the test was 101, the quietest gas was 103. So there’s overlap, but it’s tiny. The few cordless that are close to gas are the cheapest ones, which no one wants to use for anything serious.
Also, let’s talk about vibration, because that’s tied to noise too. Loud engines usually mean more vibration, right? Gas chainsaws have that two-stroke shake, which is not just noisy but bad for your hands. Cordless have much lower vibration, because the motor is balanced, and we add anti-vibration mounts. So not only is it quieter, but your hands don’t fall numb after 20 minutes of cutting, which is another win for long-term use.
Wait, should I mention anything about battery life? Maybe not too much, but some people worry that a cordless saw won’t last as long, which is true for the cheap ones, but our 60V models have enough power to cut a full cord of wood on one charge, same as a mid-size gas saw. But back to noise: even if you need two batteries, swapping one takes 2 minutes, and you’re still only dealing with a 90 dB saw, not a 105 one.
I’ve heard a lot of gas fanboys say “cordless are wimpy, they don’t have the power.” Fair, for professional-level large trees, a 36-inch gas saw is still going to outpower a 16-inch cordless. But the question here is about noise, so even if they’re more powerful, they’re way louder. It’s like comparing a lawnmower—gas push mowers are 90 dB, cordless push mowers are 75 dB. Same logic, applies here.
Let’s also clear up a myth: “If a saw is quieter, it’s less powerful.” That’s not true. The sound from a chainsaw mostly comes from the engine and exhaust, not the cutting power. We’ve tested our 60V cordless vs a 50cc gas saw—same cutting speed for most logs, but the gas one is 10 dB louder. The power isn’t the difference, the engine is. That’s a key point.
Now, who is this info for? If you’re a homeowner looking to buy a saw for cutting firewood, trimming small trees, doing yard work, our cordless models are way quieter, safer for your hearing, no noise complaints, and just as easy to use as a gas one. If you’re a pro who’s on the job all day, cordless cuts down on hearing risk, which is a huge deal for long-term health—hearing loss is permanent, no do-overs. Even if you’re just a weekend warrior who lives in a subdivision, the neighbor’s dog is barking at your old gas saw, I promise the cordless is way less annoying for everyone.
Wait, let’s talk about real-world use cases. Last summer, a customer came to us, he was a retired guy who lives in a suburban neighborhood. He had a gas chainsaw, and he said he could only use it between 10 AM and 4 PM, because his next-door neighbor works night shifts and sleeps during the day. He bought our 40V cordless, and now he cuts whenever he wants—even 8 PM on a Saturday, no one says a word. That’s not a marketing line, that’s a story I heard last month. Another customer, a tree service owner, he switched 5 of his guys to our pro cordless models, and they said they don’t leave the job with ringing ears anymore, which is a massive improvement.
I should also note that all these numbers are for saws that are properly maintained. A gas chainsaw with a clogged muffler or a dirty air filter can be even louder than the rated number, maybe 5 dB more. A cordless saw with a worn chain or a loose motor might be 2 to 3 dB louder than it should be, but still way under the gas numbers. So regular maintenance matters, obviously.
Now, let’s wrap this up. The short answer: cordless chainsaws are almost always 10 to 15 dB quieter than comparable gas chainsaws under load. That’s not just a small number—it’s the difference between needing hearing protection for every use and maybe only needing it for long sessions, between obeying noise ordinances and getting a complaint, between leaving the job with ringing ears and not.
If you’re in the market for a new chainsaw, and you care about noise, hearing health, or not annoying your neighbors, our cordless models are worth a look.
