How loud is a leaf blower?
A leaf blower is about 90 dB, with a typical range of 80–100 dB. Backpack gas blowers are the loudest; battery models are quieter.
That is about 8 times as loud to the ear as normal conversation and 1e+03 times the sound energy.
Can it damage your hearing?
Yes, with enough exposure. At 90 dBA, NIOSH recommends a daily limit of 2.5 hours; at the top of the range (100 dB) it is 15 minutes. Wear earplugs or earmuffs, keep your distance and limit time near the source.
How sound level changes with distance
Decibel figures always depend on distance. For a small source in open air, every doubling of distance lowers the level by about 6 dB; indoors, reflections reduce that drop. Use the sound-vs-distance calculator to estimate the level where you are.

| Level | NIOSH recommended limit | OSHA legal limit (US) |
|---|---|---|
| 84 dBA | 10.1 hours | 18.4 hours |

NIOSH: 85 dBA for 8 hours with a 3 dB exchange rate; OSHA: 90 dBA for 8 hours with a 5 dB exchange rate. General information, not medical advice – see a hearing professional about ringing ears, muffled hearing or pain.

Frequently asked questions
How many decibels is a leaf blower?
About 90 dB, with a typical range of 80–100 dB.
Is a leaf blower louder than a jet engine?
No – a jet engine at takeoff is about 140 dB at 30 m, while a leaf blower is about 90 dB.
How are these levels measured?
With a sound level meter, usually A-weighted (dBA) to match human hearing. Published figures depend on distance and conditions, so treat them as typical values.
