How loud is a battery leaf blower?
A battery leaf blower measures 81–91 dB, roughly as loud as a hair dryer. At 91 dB it is at or above the 85 dB line where hearing damage starts: NIOSH puts the safe limit at about 2 hours a day. Normal conversation runs about 60 dB for comparison.

| Decibel level | 81–91 dB |
|---|---|
| Hearing risk | Moderate risk — NIOSH, 2025, measured on the worker while the blower ran: 86.4 dBA on average over 39 tasks, typically 81 to 91 (one standard deviation either side), highest 96.7; about 10 dB below gas |
| Safe exposure (NIOSH) | About 2 hours 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 battery leaf blower compares
On the decibel scale, 81–91 dB sits above the 85 dB line where sustained exposure damages hearing. Sounds at a similar level:
- Hair dryer 80–90 dB
- Kitchen blender 80–90 dB
- Generator 79–97 dB
- Movie theater 74–104 dB

Is a battery leaf blower dangerous to hearing?
Yes — at 91 dB, a battery leaf blower is loud enough to damage hearing over time. NIOSH limits safe exposure to about 2 hours a day; use hearing protection beyond that.
