Garden shredded sound levels vary greatly between impact shredders, quiest shredders and on to Turbine Cut Shredders. Not all manufacturers publish sound figures so a common question on Garden Shredders is, “Just how noisy are Shredders and do I need to be using ear protection?”
As responsible citizens the answer 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.
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.
|Bosch AXT 2200||107|
|Einhell GH-KS 2440||112|
|Dirty Pro Tools 2500||111|
To understand just how noisy these machines are requires an understanding of the decibel (dB) scale. That is beyond this web site but we have provided a bunch of links out to more detailed explanations elsewhere.
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.
HSE law is that anyone 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 litttle exposure as 2minutes per day.
