How loud is a chainsaw?

A chainsaw is typically around 105 dB — comparable to a chainsaw at arm's length. That falls in the “extremely loud” band, with a safe unprotected limit of about 4.7 min.

People search “how loud is a chainsaw?” for two reasons: curiosity about the number, and a practical worry about whether it is doing damage. Here is both — the typical level, what it feels like next to sounds you know, and what to do about it.

What 105 dB actually feels like

105 dB is extremely loud and genuinely hazardous. Safe exposure is measured in minutes, not hours, and without protection cumulative damage can begin quickly. Any regular activity at this level — power tools, concerts, motorsport — calls for rated hearing protection every single time. In the specific case of a chainsaw, the figure depends a lot on distance and the exact source: measured close up it can be several decibels higher, and across a room several decibels lower. Treat 105 dB as a representative, real-world value rather than a fixed constant.

Hearing protection

For anything above 85 dB, rated protection matters. Look at the NRR (US) or SNR (EU) figure — real-world reduction is roughly (NRR − 7) ÷ 2.

Is a chainsaw dangerous?

At 105 dB, a chainsaw can damage hearing with prolonged exposure. Limit unprotected exposure to about 4.7 min, and use rated protection for anything longer. Damage at this level is painless and permanent.

How to reduce it

Distance is your first tool — every doubling of distance outdoors removes about 6 dB. Where you cannot move away, rated hearing protection is the answer: look for a high NRR (US) or SNR (EU) figure, remembering that real-world reduction is roughly (NRR − 7) ÷ 2. Our hearing-protection guide explains how to choose.

Frequently asked questions

How many decibels is a chainsaw?
A chainsaw is typically about 105 dB, though the exact figure varies with distance, model and conditions. That places it in the “extremely loud” band of the decibel scale.
Is a chainsaw bad for your hearing?
At about 105 dB, a chainsaw exceeds the 85 dBA action level. Safe exposure is roughly 4.7 min without protection, after which hearing damage can accumulate.
How does a chainsaw compare to normal conversation?
Normal conversation is about 60 dB. At 105 dB, a chainsaw is perceived as roughly 22.63× as loud and carries about 31623× the sound energy.
How can I make a chainsaw quieter?
Wear rated hearing protection when close to it, increase your distance (every doubling drops about 6 dB outdoors), and add absorbing or blocking material where possible.
