Noise from outdoor machinery can cause noise disturbance and annoyance – especially when its warm and windows are more likely to be opened. Construction sites and large parks and gardens frequently use machinery that is inherently noisy. We also use noisy outdoor machines at home in the garden and on building jobs. There is regulation in place to manage noise levels from 57 types of outdoor equipment, and this is overseen by the Office for Product Safety Standards, part of the Department for Business, Energy and Industrial Strategy. Michelle from the office gives us an introduction to the outdoor noise regulations (official title Noise Emission in the Environment by Equipment for use Outdoors Regulations 2001 (as amended) ).
Regulations on noise from outdoor equipment
The outdoor noise regulations cover a range of the outdoor machinery that is deemed to be the noisiest and have the most harmful potential noise impact on people. This is equipment used in construction, grounds and landscape management, gardening and agriculture. Machinery covered by regulation ranges from concrete or mortar mixers, hydraulic hammers, hedge trimmers and leaf blowers to refuse collection vehicles – a full list of equipment covered is in the directive and listed below.
The 57 types of equipment covered are split into two lists:
- equipment subject to noise limits and noise marking – this includes lawn mowers, motor hoes, power generators, concrete breakers and picks, tower cranes and compaction machines
- equipment subject to noise marking only – this includes chainsaws, hedge trimmers, brush cutters, hydraulic hammers, concrete or mortar mixers, mobile waste containers and water pump units.
Equipment covered by the regulation must have:
- a standard label indicating its guaranteed sound power level
- a technical file showing this has been measured correctly to ISO standardsa Declaration of Conformity, which is for the manufacturer or importer to declare that they have conducted the appropriate tests for the machine and that they pass or conform to the tests.
The regulation aims to control the noise produced by machinery and to reduce the impact on environmental noise levels – especially in urban areas where they are more likely to disturb people. The regulation also aims to encourage manufacturers to work towards reducing the noise levels of outdoor machinery through using advances in technology to innovate and develop quieter products.
When purchasing any equipment, please be aware of the noise label and choose quieter models. The higher the decibel level marked the louder the machine will be. The more that you demand lower noise levels in machines you use, the faster manufacturers will work to produce quieter equipment.
What do noise labels mean?
To put the noise number value in to better context, we all hear noise in very different ways and the term decibel (dB) is used to represent the level of noise that we are hearing. The label used reflects the measured sound power level (Lwa) recorded usually from a hemisphere around the machine at operation. Some simple values to give you an idea of the noise level represented by a decibel rating are:
A pin falling on the floor – around 15 dB
A conversation between two people – around 65dB
A motorcycle – around 100dB
A Jet at take off – around 140 dB
The noise nuisance caused is different to everyone depending on the level and pitch variations and our own hearing ability and perception of noise.
