How loud is a fuel-powered mower?
A fuel-powered mower measures 86–97 dB, roughly as loud as a tractor with no cab. At 97 dB it is at or above the 85 dB line where hearing damage starts: NIOSH puts the safe limit at about 30 minutes a day. Normal conversation runs about 60 dB for comparison.
Last updated:
| Decibel level | 86–97 dB |
|---|---|
| Hearing risk | High risk — NIOSH, 2025, measured on the worker while mowing: 91.4 dBA on average over 69 tasks, typically 86 to 97 (one standard deviation either side), highest 102.4 |
| Safe exposure (NIOSH) | About 30 minutes a day |
| Typical setting | work |

Measured on the worker, at the operator's ear. For the level farther away, such as 50 ft from a window, the sound distance calculator gives an open-air estimate.
How a fuel-powered mower compares
On the decibel scale, 86–97 dB sits above the 85 dB line where sustained exposure damages hearing. Sounds at a similar level:
- Tractor with no cab 82–100 dB
- Riding a subway 90 dB
- Movie theater 74–104 dB
- Barking dogs 88.4–100.3 dB

Is a fuel-powered mower dangerous to hearing?
Yes — at 97 dB, a fuel-powered mower is loud enough to damage hearing over time. NIOSH limits safe exposure to about 30 minutes a day; use hearing protection beyond that.
