Treadmill decibel figures come only from the makers, and eight of the twelve treadmills and walking pads we read carry one, each with a different condition or none.
No independent body rates treadmill noise. ENERGY STAR covers appliances, heating and cooling, electronics and more, but not fitness equipment. Each treadmill and walking pad figure here comes from its own maker, with no outside audit.
Eight machines have a number:
- UREVO CyberPad and FoldiMix 5L: 35dB, claimed on the product pages.
- LifeSpan TR1200Pro: under 60 dB, in the specification table.
- KingSmith WalkingPad C2: 65 decibels, described as idling noise.
- Egofit Walker Pro-M1: under 70 dB, even at maximum speed.
- BowFlex T9 and Horizon 7.0 AT: no greater than 70 dB, in their owner's manuals, with nobody on the belt at 12 km/h (7.5 mph), measured at typical head height.
- Peloton Tread Flex: "Runs at 70db", with no speed, load or distance.
Four have none. SOLE, Echelon and Sunny publish no figure for the models we checked, and some use phrases like "whisper-quiet" instead.
Notice what each figure covers. The walking pad figures come with a best case, a ceiling, idling or top speed attached, or with no condition at all. BowFlex and Horizon give an empty-belt limit at 7.5 mph, and Peloton's 70 comes with no condition.
These have different bases, so we rank none against another, and none of them describes the footstrike that reaches the floor below.
Running in an apartment means a louder machine and a heavier footfall at once, which is why we cover the quietest treadmill for running on its own.
Our later guide to the quietest walking pads looked at more pads and more manuals, more than forty walking pads and under-desk treadmills from ten brands, and found some figures that say what they cover: idling, no load or top speed.
Why can a 35dB claim and a 65 dB manual both be true?
A 35dB claim and a 65 dB manual figure can both be true because UREVO's manual states a ceiling while its product page states a best case.
UREVO's product page says 35dB. The safety page of the same machine's manual says this: "On airborne noise: ≤65dB." The line before it reads: "Noise emission under load is higher than without load."
These do not strictly contradict each other. The manual states a ceiling, the most the machine should produce. The product page states a best case, under test conditions UREVO does not describe.
But it tells you how to read every figure in this category. A walking pad measured with nobody on it is not the walking pad you will hear at 9 pm.
KingSmith deserves credit here. Its 65 decibels is labelled as idling noise, which means the belt turning with no walker. That is a worse-looking number than 35, and a more useful one, because you know what it describes.
The same caution applies beyond noise. UREVO's pages list a 400 lb capacity for both of its machines here. Both manuals say 136 kg, which is 300 lb. When the marketing and the manual disagree, we quote the manual.
Can downstairs neighbors hear your treadmill?
Yes, downstairs neighbors can hear a treadmill, but mainly your footsteps: NordicTrack's advice for apartment owners says that footstrike impact, not motor hum, is the noise that travels to downstairs neighbors.
This is the most important point in the guide, and it comes from a treadmill maker. Impact travels from the deck, through the frame and into the floor.
A machine with no footstrike puts far less into the floor, which is the case for our guides to exercise bikes for an apartment and the quietest rowing machines.
Three things follow.
Walking is far gentler than running
NordicTrack points out that a sustained incline walk involves significantly less footstrike force than running. That is a good reason to value incline on a walking pad. LifeSpan takes the opposite view for desk use, and offers no incline because, it says, ergonomists do not recommend walking on an incline while working.
Your building matters more than your treadmill
In NordicTrack's words, a concrete slab building transmits very little vibration between floors. In a wood-joist building with a thin subfloor, setup matters more. It suggests placing the machine closer to an interior load-bearing wall, not in the middle of an open floor, and keeping it off shared walls.
A robot vacuum's self-empty dock raises the same shared-floor problem; see the apartment section of our robot vacuum guide.
No maker says its treadmill is safe for an upper floor
We looked. None of the manuals or product pages we read makes any promise about upstairs use.
How do you make a treadmill quieter in an apartment?
A treadmill gets quieter in an apartment on a dense rubber mat that extends beyond its footprint, on a hard floor or thin carpet and never on shag, because the mat matters more than the machine.
Peloton's support pages put it plainly: a hardwood or concrete floor can create more reverberation and noise than a carpeted floor or a heavy rubber mat. NordicTrack adds that the mat should extend beyond the machine's footprint on every side, and that thin foam mats don't do much.
Egofit tells buyers of its small walking pad that a carpet or mat will reduce vibration and sound further. Sunny's manual makes it an instruction.
Deep carpet is a different matter. SOLE's manual says not to operate the treadmill on deeply padded, plush or shag carpet, and warns of damage to both. LifeSpan says thick carpeting blocks the airflow under the machine. So the rule is a dense rubber mat on a hard floor or thin carpet, and never shag.
Level the machine as well. NordicTrack says to check that all four feet make solid contact with the floor, adjust the leveling feet, and make sure the frame bolts are snug. A treadmill that rocks will rattle.
How much should you spend?
Around $300 to $450 buys a walking pad: the UREVO CyberPad, the KingSmith C2 or the Egofit M1. These are light, they store under a sofa, and they carry short warranties and lower weight limits. Check the user limit in the manual, not on the product page.
Around $600, the Sunny Pacer adds jogging speed and automatic incline.
Around $1,100 to $1,300, the choice splits. The LifeSpan TR1200Pro is built for walking many hours a day, with a 10-year frame warranty. If it will sit under a desk, the desk's own motor is worth checking too; our guide to the quietest standing desks looks at the motor noise ceilings desk makers publish.
The SOLE F63 is a full running treadmill with a lifetime warranty on frame and motor. Neither does the other's job.
Above $2,000 you are paying for something other than quiet: a curved manual deck, a large screen or a subscription platform. Of the machines at that level, Peloton's Tread Flex prints "Runs at 70db" with no condition, and SOLE's curved C80 prints nothing.
How do you keep a treadmill belt quiet as it ages?
Keeping a treadmill quiet as it ages means lubricating the deck on the maker's schedule and tightening loose hardware.
A dry belt drags, and a belt that drags gets louder. Makers set schedules.
SOLE's F63 lights a lubrication reminder after 90 hours of use, and says failing to lubricate the deck at regular intervals may void the warranty. LifeSpan says every 50 hours or three months. Egofit says the same. Sunny's reminder appears every 188 miles.
New machines make noises that pass. Peloton describes a thump and a chirp as normal sounds while a new Tread breaks in, and says they fade with regular use.
Loose hardware is the other common cause. If a quiet treadmill starts to rattle, tighten the frame bolts and check the feet before you blame the motor.
Where do apartment treadmill buyers go wrong?
Apartment treadmill buyers go wrong in five common ways, from ranking walking pads by decibel claims to putting the machine on thick carpet to quiet it.
Ranking walking pads by decibel claims
The published figures describe different conditions: one is idling, one is at maximum speed, and two give no conditions at all. They cannot be placed in order, and any site that does so is guessing.
If the complaint comes from downstairs, a quieter motor will not fix it. A mat, a better position in the room, and walking in place of running will.
Trusting the capacity on the product page
Two of the twelve machines we checked list a higher user limit on the page than in the manual.
Putting the treadmill on thick carpet to quiet it
Makers warn against it, for the sake of both the carpet and the machine.
Assuming a manual treadmill is silent
It has no motor. It still has you.
UREVO's 35dB best case and KingSmith's 65 decibels at idle describe different conditions, so a best-case figure and an idle figure from two treadmill makers cannot be ranked against each other.
Every published figure here describes the machine you hear, not the footfall downstairs, so judge each against the room you will be in, as our room-by-room page on how quiet is quiet enough explains.
If your treadmill has grown louder with age, its makers blame the dry belt and loose bolts covered above; both come up again in why your appliance got louder.
