3M E.A.R. Hearing Protection.
When 3M took over E.A.R. they confirmed their position as the Leaders in Hearing Protection, with a range of 3M E.A.R ear plugs, as well as the market leading 3M Peltor Optime 1,2,3 range of ear muffs.
Health and Safety regulations require suitable hearing protection where noise levels exceed 80 decibels (dBA). Here are some typical decibel (dBA) levels of everyday situations:
normal speech - 60-65 dBA
a busy street - 78-85 dBA
lawn mower - 85 dBA
forklift truck - 90 dBA
hand drill/angle grinder - 98 dBA
music venue/nightclub - 110 dBA
heavy lorry about 7 metres away - 95-100 dBA
chainsaw - 115-120 dBA
Measure the noise at work with a 3M Noise Indicator - it's a handy, small ,portable, noise monitor (Our code PNI01PC).
Once you know the current noise levels (db) in the workplace, you can best choose the most suitable ear defenders to reduce your exposure to the noise levels.
Earmuffs or Ear Defenders: whatever you call them, they should cover your ears fully, fit tightly, and have no gaps around the seals.
Earplugs: They go right into your ear canal, not just across it. Some types you use only once (disposable), others can be re-used and even washed.
When it comes to hearing protection, we dont want to hear any excuses: Here you can choose from the basic 3M E.A.R. Classic Foam Earplugs to the 3M Peltor H540A Optime III ear defender performing 35dB Sound Noise Reduction (SNR). We are tempted to use them at home?

It is a established fact that noise can have serious consequences at physiological and psychological levels. In effect, noise creates a real pollution for everyone's health.
EN352 Standard: head fasteners and ear plugs
The EN352 European standard is separated into several parts. Every part of the standard is appropriate to specific types of protection :
EN 352-1, EN352-2 and EN352-3 standards deal with safety requirements and tests, individually regarding head fasteners, earplugs, and head fasteners fixed on protective industrial helmets.
These standards create requirements in regards to the manufacture, design and performances, test methods and the instructions involving the marking and information intended for the users.
These standards specify the provision of information relating to head fasteners acoustic fading characteristics, measured in predictability with EN 24869-1 : 1992 standard, and therefore specify a negligible fading level necessary to create their conformity with the present specification. Only hearing protection products with an suitable certification mark can be selected. All the hearing protectors has the EC marking mandatory by the personal protective equipment directive.
In selecting hearing protection, it is vital to acknowledge the laws, regulations, uses and techniques. The previous criteria underline the general points for consideration when selecting. For further details concerning selection please refer to the European standard EN458 : 1996 (Title : Auditory protection - Recommendations for selection, use and maintenance).
Please note: rnr* recommended noise rating
At noise levels above 95dB you will need to get an accurate noise valuation to correctly select the right ear plug or ear muff. Green and yellow marked products are NOT appropriate for use in low frequency noise. Choosing the correct hearing protection for your needs can be difficult. You need to make sure you provide the correct level of defence to ensure that workers are not over-protected and that a suitable product is chosen. 3M E.A.R. and 3M Peltor have developed this easy-to-use selection system that helps correct choice.
The system uses a simple, logically coloured grouping to make the selection process easy.
1)Find out what your noise level is?
2) Then look at the above icons and create which band (RNR) the noise level falls into.
rnr* - 85dB You don't have to wear hearing protection, but it must be made obtainable to all exposed persons.
rnr* - 83dB - 93dB You're above the level, hearing protection is obligatory.
rnr* - 87dB - 98dB You're above the level, hearing protection is required. Perfect for high frequency noise.
rnr* - 94dB - 105dB You are above the level, hearing protection is required. Ideal for high and medium frequency noise.
rnr* - 95dB - 110dB You are above the level, hearing protection is required. Ideal for all frequencies.
