If you want a treadmill quiet enough for an apartment or a house full of sleepers, shop for a 3.0 HP or larger DC motor, a cushioned deck, and slow, smooth incline changes, then add a mat and headphones. No motorized treadmill is silent. The Sole F80 suits bigger users who want a planted, quiet machine. The Horizon T101 suits budget walkers. The NordicTrack Commercial 1750 suits runners who love hills, and a manual AssaultRunner suits runners who want to lose the motor entirely.
The problem is that most quiet claims are marketing. A treadmill that sounds fine in a showroom can thump through a floor, whine on every incline change, or beep at every button press. Published decibel readings also use different methods, so two lists can disagree about the same machine.
This guide covers eight picks matched to different buyers, explains what actually makes a treadmill loud, and shows you how to read a decibel number. The first three picks are machines our reviewer at Big Guy Treadmill Review has tested. The rest earned a place through their noise readings and specs. A final section covers how to quiet a treadmill you already own.
What makes a treadmill quiet
A treadmill runs quietly when its motor, incline mechanism, and deck all stay calm under your weight. Each one makes a different kind of noise, and each needs a different fix.
Motor and incline noise
The drive motor sets the baseline hum. DC motors are quieter than AC motors, and smaller treadmills often use brushless versions that are quieter still. For running, 3.0 HP continuous duty is a sensible floor, because an undersized motor works harder and sounds like it.
Load matters, especially if you weigh 200 pounds or more. In our testing of the ProForm Pro 2000, a belt set to 6 mph ran at 6.06 mph unloaded and 5.78 mph with a 270-pound user. A motor that gives up that much speed is working hard, and a motor that works hard is rarely quiet.
The incline motor is the surprise. Even with a whisper quiet drive motor, a separate incline motor can add a grinding burst every time you change grade. Slow adjustments tend to be quieter. Our Sole F80 takes 15 seconds to go from 2 mph to 8 mph, a deliberate pace that keeps the motor calm but frustrates anyone doing short intervals.
A quiet drive motor can still ruin your workout if the incline motor shouts every time you change grade.
Foot impact and deck cushioning
Foot noise is the part no spec sheet can promise. Running style, shoes, fatigue, and body weight all change it, so one treadmill can sound like a mouse under one runner and a drum under another. Walking is quieter than running because each step puts less force into the deck.
A cushioned deck absorbs some impact, which gives the sound less energy to work with. It also sends less shock into the floor, and the floor is what your downstairs neighbor hears. Heavier users hit harder, so for a 250-pound runner frame stiffness and deck quality matter more than a headline horsepower number.
How to read decibel numbers
Decibel readings only compare when they are taken the same way. One test measured the NordicTrack Commercial 1750 at 50.8 dB at 3 mph with nobody on it. Another averaged about 69 dB across distances during real use. The gap comes from speed, load, and distance. A 10 dB difference is generally heard as roughly twice as loud, so that gap is not small.
| Everyday sound | Approximate level |
|---|---|
| Soft whisper | 30 dB |
| Rainfall | 50 dB |
| Normal conversation | 60 dB |
| Dishwasher or washing machine | 68 to 70 dB |
One group of testers measured more than 50 treadmills and found an average of about 68.5 dB from five feet away, close to a running dishwasher. So quiet usually means a few decibels below average plus a less irritating sound. Judge the kind of noise (whine, thump, beep) as much as the number.
A quiet treadmill is rarely a silent one; it is one whose noise stays pleasant and stays out of the next room.
1. Sole F80: quiet and stable for bigger users
The Sole F80 is the quiet treadmill we recommend first for bigger users who want to stay under $2,000. Its Z-shape frame gives it a stable feel that keeps rattles down at running pace.
How quiet it is
Our reviewer describes the F80 as quiet and stable, and published testing agrees: with a runner on the deck, its noise stayed lower than the other machines in that test. The incline moves slowly, and acceleration from 2 mph to 8 mph takes 15 seconds. That unhurried behavior is a big reason the motor stays calm.
Cushioning is where opinions split. Sole calls it a Cushion Flex Whisper deck, and one test found it comfortable but not plush while another found it firm for easy recovery runs. Try it in the shoes you run in, because foot noise depends on your stride more than on the brochure.
The F80 trades fast adjustments for a quiet, planted run.
Specs and price
At $1,899, here is what you get:
- Warranty: 3 years parts, 1 year labor
Who it suits
Pick the F80 if you weigh over 200 pounds and walk or run long, steady miles. Its heavy-duty Z-shape frame gives bigger users a stable, planted run.
Skip it if your workouts are short HIIT intervals, because the slow speed and incline changes will frustrate you. Measure your space before you order.
2. Inspire Fitness Tread 3: a quiet entry-level fold
The Inspire Fitness Tread 3 is a quiet, stable, folding entry-level treadmill for lighter users or anyone on a tighter budget. It is the one pick here where we tell bigger users to wait.
How quiet it is
Our review page calls the Tread 3 quiet and stable. Stability is half of quiet, because a frame that does not shake does not add a rattle to the motor sound. We have no decibel figure to quote, so treat "quiet" here as a reviewer’s impression rather than a measurement.
A 20" x 55" belt works for walking and light jogging, but a long stride has little room. Taller users end up shortening their steps, so test it at your normal pace before you commit. You should also confirm the return terms before assembling it.
Stability is half of quiet, and the Tread 3 is built to stay put.
Specs and price
- Price: $1,200
- Belt: 20" x 55"
- Folding design
- FTMS Bluetooth, which lets compatible training apps connect
- Our reviewer does not yet recommend it for heavier users
Who it suits
This is a fit for lighter walkers and joggers who want a folding machine with calm manners and a mid-range price. Because FTMS Bluetooth is built in, you can follow a class on your own tablet and keep the sound in headphones.
If you weigh 200 pounds or more, the Sole F80 above is the safer buy. Our reviewer wants more time to judge the Tread 3’s reliability before pointing heavier users to it.
3. Horizon Fitness T101: best quiet budget pick
The Horizon Fitness T101 is the quiet treadmill to buy if you have under $1,000 and mostly walk. Our reviewer found it surprisingly solid and simple to use, and it sells for $699.
How quiet it is
Published testing calls Horizon one of the quietest brands, and the T101 fits that pattern. Its incline and speed changes are fast but stay quiet, which is unusual at this price.
Stability is the caveat. One tester found it a little shaky at higher speeds, though walking caused no problems. A shaky frame adds noise, so run it at your top speed before the return window closes.
For a walker on a budget, the T101 is quiet where it counts: the motor and the incline.
Specs and price
- Price: $699
- Warranty: 1 year parts, 1 year labor
Who it suits
Walkers and light joggers get the most from the T101. Our reviewer calls it possibly the best option under $1,000 but is clear that it is not a guarantee of long-term durability.
Step up to the Horizon 7.0 AT or the Sole F80 instead.
4. Horizon 7.0 AT: best quiet folding treadmill for runners
The Horizon 7.0 AT is the best quiet folding treadmill for runners at around $1,000. It is not silent, but it keeps the folding action and the controls calm and gives you a full 60-inch deck.
How quiet it is
Honesty first: in one test the 7.0 AT routinely measured over 70 dB, comparable to a washing machine, and the tester said it was not the quietest machine she had used. It earned its place on value and balance. The gas-shock folding also lowers the deck softly, so it does not slam when you unfold it.
If you want more quiet headroom, look at the Horizon 7.8 AT. One test called it the quietest motorized treadmill it had measured. It has a 4.0 HP motor, a 22" x 60" deck, and a 375-pound weight capacity.
The 7.0 AT is a runner’s treadmill that is quieter than its price suggests, not quiet in absolute terms.
Specs and price
- Price: about $999
- Deck: 20" x 60"
- Speed 0.5 to 12 mph, incline up to 15%
- Motor: 3.0 CHP
- Weight capacity: 325 lbs
- FeatherLight folding, about 277 lbs
- Bluetooth for apps like Zwift and Peloton, no touchscreen
- Warranty: lifetime frame, 3 years parts, 1 year labor
Who it suits
Runners who bring their own tablet and want a long deck, steep incline, and easy folding will like it. The 15% incline is more than most treadmills near $1,000 offer.
If you want built-in streaming or iFIT, it is the wrong machine. Users near the 325-pound limit should look at the 7.8 AT or the Sole F80.
5. NordicTrack Commercial 1750: quiet with incline and decline
The NordicTrack Commercial 1750 is the quiet treadmill for people who want serious incline training and built-in classes. It has the best published noise numbers of any motorized machine in this list.
How quiet it is
One test measured it at 50.8 dB at 3 mph with no one on it, and another averaged about 69 dB across distances in use. The incline motor was so quiet one tester double-checked that it was moving, and NordicTrack’s "quiet drive" design covers incline and decline changes. A cushioned deck helps dampen foot noise.
All three testers in another review rated its noise 5 out of 5. That fits the rule from earlier: it is a quiet machine, not a silent one.
The 1750 earns its place by keeping incline changes quiet, which is where most treadmills give themselves away.
Specs and price
- Price: $2,299
- Incline: -3% to 12%, top speed 12 mph
- Deck: 60 inches long
- Tilting HD touchscreen with iFIT (subscription required for full use)
- Warranty: 10-year frame, 2 years parts, 1 year labor
- Footprint: about 21 square feet
Published weight ratings range from 300 to 400 pounds, so confirm the current spec sheet. At the $39.99 monthly iFIT price listed in one review, a year adds about $480, which puts the first year near $2,780.
Who it suits
Hill trainers and class lovers get the most from it. The decline option is rare and it keeps its quiet incline motor. The downsides are its size and weight, and the fact that the warranty is voided if you store or use it in a garage.
6. ProForm Carbon TLX: quiet midrange fold for apartments
The ProForm Carbon TLX is the best quiet treadmill for an apartment on a midrange budget. It folds compactly, takes iFIT through your own device, and runs quieter than average.
How quiet it is
Two tests measured it at roughly 68 to 69 dB, about average, and both testers called it a little quieter than average in feel. ProShox cushioning helps with foot noise, though one tester said it is only fine for the price. The incline makes some noise when it moves, which is expected.
Folding is the other apartment win. Hydraulic assist lowers the deck gently, and folding cuts the footprint by about half.
In an apartment, a treadmill that folds away quietly beats one that is slightly quieter but always in the way.
Specs and price
- Price: roughly $1,000 to $1,500, depending on sales
- Motor: 3.0 CHP
- Deck: 20" x 60"
- Incline up to 12%
- Weight capacity: 300 lbs, about 249 lbs weight
- 7-inch display, no touchscreen
- 10-year frame warranty, with short parts and labor coverage
Who it suits
Apartment dwellers and walkers who want a long deck and folding will like it. Plan to prop your phone or tablet on the media shelf for iFIT.
Heavier runners near the 300-pound limit should look at the Sole F80 first. The short parts coverage is worth weighing too.
7. Peloton Cross Training Tread: quiet classes
The Peloton Cross Training Tread is the quiet treadmill for people who want studio classes at home and have the budget. It costs over $3,000 and does not fold.
How quiet it is
One tester compared it with several Bowflex treadmills and found it the quietest. Another review says it can still be heard and that it is quieter than many others. The most likely noise source is the speaker system, which is high quality, so keep volume in check.
The 3.0 HP DC motor runs up to 12.5 mph, and incline goes up to 12.5%. There is no decline, and cushioning is minimal, so foot noise falls on you and your shoes.
The quietest part of a Peloton Tread workout is the machine, and the loudest part is usually the class.
Specs and price
- Price: over $3,000, plus a monthly class subscription
- Deck: 20" x 59"
- Speed 0 to 12.5 mph, incline up to 12.5%
- 21.5-inch touchscreen
- Does not fold
- Warranty: 5-year frame, 3 years motor and belt, 30-day home trial
Who it suits
Class enthusiasts who have a permanent spot for it will love the programming. The 30-day home trial helps if you want to check the noise in your own home.
If you need to fold it away or you want the lowest cost of ownership, skip it. Weight capacity is worth confirming first if you are a bigger user.
8. AssaultRunner Elite: quiet treadmill for running without a motor
The AssaultRunner Elite is the quiet treadmill for running if you want no motor at all. It is a user-powered curved treadmill, so there is no drive hum and no incline motor.
How quiet it is
In one test, a manual treadmill measured about 25% quieter than the motorized machines it was compared with. You still hear the belt rolling and your footfalls, and the heavy slats can rumble. Because speed is set by you, intervals change as fast as you do.
It takes some practice. The curved belt is harder than a motorized treadmill, and the learning curve can discourage newer runners.
A manual treadmill removes the motor whine completely, but it cannot remove the sound of your own feet.
Specs and price
- Price: $3,999
- Deck: 17" x 62.2", curved
- Weight capacity: 400 lbs, about 289 lbs weight
- No electricity, no incline or speed settings
- Warranty: lifetime belt, 10-year frame, 3 years parts, 1 year labor
Who it suits
Runners who like hard intervals and have a permanent spot will get the most out of it. The 400-pound capacity also suits bigger users, but the price is more than double most home treadmills.
Walkers and anyone who wants steady, easy miles should pick a motorized machine instead. Assembly can also be fiddly, as one tester struggled to get plastic pieces flush.

| Peloton Cross Training Tread | over $3,000 | 20" x 59" | No | Quieter than many, speakers loud |
| AssaultRunner Elite | $3,999 | 17" x 62.2" | No | About 25% quieter than motorized |
Which one fits your situation
Match your use, then your budget:
- Bigger user, under $2,000: Sole F80.
- Lighter user, tight budget: Inspire Tread 3 for a quiet fold, Horizon T101 for mostly walking.
- Runner at about $1,000: Horizon 7.0 AT.
- Hill workouts and classes: NordicTrack Commercial 1750.
- Apartment, midrange budget: ProForm Carbon TLX.
- Studio classes and a big budget: Peloton Cross Training Tread.
- No motor at all: AssaultRunner Elite.
- Gym-size machine for bigger runners: the 3G Cardio Elite Runner, $4,250, which has room for big users and no required membership fee. We have no decibel figure for it.
- Compact walking pad: the WalkingPad X218, $1,799. It has no incline, so there is no incline motor to hear, and our reviewer found it capable of light jogging.
For the wider checklist on motor, frame, and warranty, our treadmill buying guide walks through it.
Pick the treadmill that fits your weight, your stride, and your floor, then let the noise numbers break the tie.
How to make a treadmill quieter
You can cut a treadmill’s noise with a mat, basic maintenance, and a few habit changes. None of these will make a loud treadmill silent, but together they make a real difference.
Start with the floor
Put the treadmill on a treadmill mat. Most manufacturers recommend one, and it cuts noise while protecting both the floor and the machine. Hard floors carry sound easily, so a soft surface under the mat helps even more.
If you live above someone, the mat matters most. Choose workout times with your neighbors in mind and tell them your plans, which tends to solve problems before they start. Open communication matters as much as the mat.
Maintain the machine
Many unexpected noises come from neglect. Dust builds up around the motor, belts drift off center, and feet go out of level. A five-minute check handles most of it:
- Unplug the treadmill and vacuum dust from the motor hood area.
- Level the feet so the frame does not rock.
- Check that the belt runs centered.
- Lubricate the belt if your manual calls for it, since some belts need it and some do not.
- Tighten loose bolts and re-seat the mat.
Follow the maintenance schedule in your manual. Improper use can cause creaking or squeaking too.
Change where and how you use it
Place the treadmill away from shared walls and living areas, but think twice about a garage. Many manufacturers void the warranty when a treadmill is used or stored in one. The temperature swings and dust are not good for it either.
Pair Bluetooth headphones with your treadmill so music and class audio stay in your ears. Turn off button beeps if you can. If you cannot, avoid interval programs that need constant button presses. Walking is quieter than running, and shorter, softer strides reduce foot noise.
The cheapest quiet upgrade is a mat, a level frame, and a clean motor hood.
Getting the quiet you paid for
A quiet treadmill comes from the right motor, a stable frame, a cushioned deck, and a calm incline. Then it depends on your floor, your upkeep, and how you use it. Read decibel numbers cautiously, because testing methods differ and your own stride changes the result.
If you are still weighing machines, our treadmill comparison chart scores every treadmill we have tested, sound level included, alongside motor, deck, incline, cushioning, warranty, and current price. Use it to narrow your shortlist to the machines that fit your body weight, budget, and floor.
