How To Compare Garden Shredder Sound Levels

In This Article

Garden shredder sound levels vary greatly between garden shredders. Impact shredders are the loudest, most raucous models on sale. It is not always easy to see how to compare garden shredder noise levels. Not all manufacturers publish sound figures.

Where the sound figures are published they are often hidden away in the small print. What’s more, sound levels are measured in decibels (dB). Unless you are a scientist, the decibel scale is not easy to understand.

So, in this article we are going to help you compare the noise levels of typical garden shredders. To do this we are going to answer 4 questions:

  • Just how noisy are Garden Shredders?
  • How do impact shredders compare to quiet shredders?
  • What to the noise levels quoted actually mean?
  • Do I need to be using ear protection?”

The answer to the last question is easy – “Yes, wear ear, eye and hand protection whenever you use any garden machinery”. There is a bit more to it than that of course.

Just How Noisy Are Garden Shredders?

Rapid Shredders Sound Levels

All rapid shredders are noisy. It is a feature of the way in which they work. A high speed motor, driving a high speed rotating blade which chops into the clippings you put in the Shredder is a recipe for lots of noise.

We include noise levels for some of the most popular rapid shredders below.

To understand just how noisy these machines are requires an understanding of the decibel (dB) scale. That is beyond the scope of this web site but we have provided a bunch of links out to more detailed explanations elsewhere.

HSE regulations stipulate that employees working in an environment where the sound level is above 85dB should always wear ear protection. For most of us, short exposure to sound at this level will not cause lasting harm. However, exposure to sound in the 105-112dB range could cause hearing damage in as little exposure as 2 minutes per day.

For this post we have created the comparative table below. You can see that rapid shredders fit right in the middle of the red, dangerous zone.

While not scientific, a change of 10dB is normally agreed to represent a doubling of volume. While the Tacklife PWS02A at 105dB is well within the red zone, it is much less noisy than the Einhell at 112dB

How Do The Noise Levels of “Quiet” Garden Shredders Compare?

It’s not a surprise that impact shredders are do noisy. They rely on blades, rotating at high speed, to chop branches and cuttings into small pieces. All high speed rotating machinery is, unless heavily sound proofed, inherently noisy.

How then do the quiet or silent garden shredders compare?

We have summarised our findings in the following table.

It is clear that, while quiet shredders are much quieter than impact shredders, they are still not quiet. The slower rotating crushers/cogs create much less external noise as expected. They can be very quiet at idle. When you start feeding them some challenging cuttings they still need to generate some power. That results in them generating more noise.

That said, I own a Bosch AXT 25D. We have put some pretty major branches through it. At no time have I found it to be loud. You can have a conversation next to it while it is in operation so it cannot be overly noisy.

The quietest of all the electric shredders is the wonderful Bosch AXT 25TC. It has been the best electric garden shredder you can buy for many years now. Only petrol machines can cope with larger branches. Petrol garden shredders are, without exception, very noisy.

There is only one sensible answer – “Wear ear protection if you are using any rapid shredder”

If you get something like the combined helmet, visor and ear defenders below, you will be set up for just about any circumstances.

Chainsaw/Brushcutter Safety Helmet c/w Chin Strap Pro
  • A ratchet system to allow the user to alter the size of the helmet with a simple twist of a knob, one size fits all.
  • A steel mesh visor allowing maximum visability and protection which can be positioned at a 90 degree angle when not in use.
  • High quality ear muffs which can also be positioned over the helmet when not needed.
  • The helmet is manufactured from high density polyethylene material.
