The 3M™ Optime™ Alert system consists in a simple and logical colour scale ( green - yellow - red) that will help you to select the optimal hearing protector associated to the noise level measured.
First action is to measure the current noise. Then you just have to look at the colours and symbols: in which colour zone are you in? Based on that input, the App will direct you to the right 3M hearing protector.
3M is the manufacturer of Hearing protector for more than 50 years and markets brands like E-A-R™ and Peltor™. 3M can provide the right hearing protector to most noise levels, most applications and to any user.
You can find our 3M™ Optime™ Alert symbols on more than 500 ear plugs and ear muffs references from 3M. This app will only give you a recommendation and is not meant to replace a proper risk assessment of your noise area. For more details, you can refer to our certified measurement tools.
