Are under-desk treadmills loud downstairs?

Yes — under-desk treadmills (walking pads) can be loud downstairs, and the noise is often more noticeable to the person below than to the user.

The main issue is usually vibration and impact noise traveling through the floor, not just the motor sound. Downstairs neighbors may hear a low, rhythmic thumping or humming, especially on wood-framed floors.

What helps reduce noise:

1. Use a thick anti-vibration mat or rubber gym mat under the machine.
2. Keep the speed low; faster walking usually creates more vibration.
3. Use softer footwear and avoid heavy, stiff-soled shoes.
4. Place it on a more solid floor if possible — concrete usually transmits less vibration than timber/joist floors.

Noise varies a lot by the building, the treadmill, and the floor structure, so exact results can differ significantly. If you’re trying to avoid bothering someone downstairs, it’s worth testing it for a few minutes in the intended spot before regular use.
