Headband and Helmet Mounted Ear Muffs, Passive and Active, and Ear Plugs from Howard Leight, Bilsom, E.A.R., Protector (Scott) and also economy options.
Ear muffs conform to EN352-1 (Headband) or EN352-3 (Helmet Mounted). Each model is assigned an SNR (Single Number Rating) which acts as a quick guide to attenuation - the higher the number the greater the attenuation. This is extended by three values H, M, L which are a measure of attenuation at different frequencies High, Medium and Low. Full attenuation data is supplied with each product.
Ear plugs conform to EN352-2. Similar information is available for these products.
Please make sure you don't fall foul of the new Control of Noise at Work Regulations 2005 which reduce Levels for Action by 5dB to 80dB and 85dB respectively for the Lower and Upper Exposure Action Values (LEAV and UEAV). It is estimated that an extra 1.1 million people in the UK will now need to be protected from noise risk.
