A petrol lawnmower runs at around 90 decibels. A circular saw hits 109. At 85 dB your hearing starts to take damage after about eight hours, and at 100 dB that window shrinks to roughly fifteen minutes. Most of us spend a Saturday afternoon mowing, sanding, or cutting without giving any of this a thought, and that is the problem. This guide covers how to pick the right ear protection for DIY and garden work, what those decibel numbers actually mean for your ears, and how to protect your hearing without making the job harder.
We checked tool decibel levels against HSE noise guidance and independent hearing-protection data, then compared the reusable and disposable options most DIYers actually reach for.

1. Work out how loud your tools really are
Before you buy anything, it helps to know what you are up against. A quiet electric mower sits around 75 dB, roughly the volume of a busy road. A petrol mower pushes past 90 dB. An angle grinder or circular saw can hit 105 to 110 dB, which is louder than a building site. The HSE sets a first action level at 80 dB and a stricter one at 85 dB, the point where employers must legally provide hearing protection. Your garage does not come with that rule. Your ears do not know the difference.
2. Understand how long you can safely run a tool
Damage comes from volume and time together, not volume alone. At 85 dB you have roughly eight hours before the risk starts to climb, and every 3 dB louder halves that time. So 88 dB gives you four hours, 91 dB gives you two, and by 100 dB you are down to around fifteen minutes. Sanding a door for half an hour might be fine. An afternoon with a petrol strimmer is not. If a tool leaves your ears ringing afterwards, that ringing is a warning, not a badge of honour.
That muffled feeling or ringing is called a threshold shift. It usually fades, but the damage stacks up over the years, and noise-induced hearing loss from power tools is permanent once it sets in. There is no cure, only prevention.
3. Choose reusable earplugs over disposable foam
Foam plugs are cheap and better than nothing, but they have real drawbacks for DIY. You have to roll and insert them correctly every single time, most people fit them too loosely to get the rated protection, and they muffle everything so heavily that you cannot hear a warning shout or your own tool changing pitch. Reusable filtered earplugs fix the loose-fit problem with a moulded seal and lower noise evenly, so speech and alarms stay audible while the dangerous volume comes down. For regular garden and DIY work, a reusable pair like the BOLLSEN WorkPRO pays for itself and protects you better at the same time.
4. Check the certification before you trust the number
Any earplug can print a decibel figure on the packet. Far fewer are independently tested to prove it. Look for products certified by a Notified Body, the independent labs that verify protection claims against a recognised standard. The BOLLSEN WorkPRO is tested and certified by PZT GmbH in Germany, so the 24 dB figure comes from a lab rather than a marketing team. For garden and DIY noise in the 90 to 110 dB range, an even 24 dB reduction brings you back into the safe zone with room to spare.
5. Get the fit right so the protection actually works
The best earplug in the world does nothing if it leaks. A poor seal can cost you 10 dB or more of real-world protection. Pick the right size for your ear canal, insert until the plug sits flush, and check that sounds dull noticeably when you cup and uncup your ears. If one size never quite feels right, BOLLSEN offers AR KI TECH, an AI ear-measurement service that uses two photos of your ears to recommend the correct size, and it has helped cut returns to around 3 percent. A proper seal is the difference between feeling protected and being protected.

Best for: one-off jobs & tight budgets
Foam plugs are the default for most sheds, and there is a reason for that. They cost very little, they pack a high rated reduction when fitted perfectly, and you can buy them in bulk and throw them away. The catch is that perfect fit. Rolled too quickly or inserted too shallow, they give a fraction of the protection on the packet, and they block sound so flatly that conversation and warning noises disappear with the danger.
- Very cheap and widely available
- High rated reduction when fitted correctly
- Easy to fit too loosely, losing real protection
- Muffle speech and alarms heavily
- Single-use, so the cost and waste add up over time
Frequently Asked Questions
How loud is a lawnmower in decibels?
A petrol lawnmower typically runs at 90 dB or more, loud enough to risk hearing damage within a couple of hours. A corded or battery electric mower is quieter, usually around 75 dB, but a full afternoon of mowing still adds up. If you use a petrol mower regularly, hearing protection is worth it.
How long can I use a power tool before it damages my hearing?
At 85 dB you have roughly eight hours. The safe time halves for every 3 dB increase, so 90 dB gives you about two and a half hours and 100 dB only around fifteen minutes. A circular saw at 105 to 110 dB can start causing damage in minutes, so protection is essential.
Do I really need ear protection for an angle grinder or circular saw?
Yes. Both regularly exceed 105 dB, which puts you at risk of damage within minutes. These are among the tools where hearing protection matters most, even for a short cut.
What NRR or SNR rating do I need for garden and DIY tools?
For most garden and DIY noise an SNR of around 23 to 25 dB, or an NRR of 25 or above, brings even the loudest common tools back to a safe level. The BOLLSEN WorkPRO delivers 24 dB of certified, even reduction, which covers the typical 90 to 110 dB range comfortably.
Are earplugs or earmuffs better for DIY?
Both work. Earmuffs are quick to put on and take off for short jobs, while earplugs are lower profile, fit under helmets or hats, and are more comfortable in heat or for long sessions. Good filtered earplugs also keep speech and warnings audible, which earmuffs can muffle. Plenty of people use plugs for general DIY and add muffs over the top for the very loudest tasks.
My ears were ringing after using power tools. Is the damage permanent?
Ringing or muffled hearing after loud work is a temporary threshold shift, a sign your ears were overloaded. It usually fades within a day or two, but it is a clear warning. Repeated exposure causes permanent, cumulative damage that cannot be reversed, so take the ringing as your cue to protect your hearing from then on.
