Enjoy flexible connection options. These safety ,ear muffs, give you the option to connect your mobile phone or audio device through Bluetooth or a 3.5mm audio input.
The Control of Noise at Work Regulations 2005 is the legislation that, amongst others, established the standards regarding the protection required when working in environments with different noise levels. The legislation established three noise level values to look out for namely: 80dB with a peak sound pressure level of 135 dBC - The lower exposure level.
In simplified form, an NRR or ,SNR, rating indicates the level that a noise can be reduced by wearing a hearing protection device. Example: If you have a noise level of 110 dBA and you have a NRR or ,SNR, of 30, then the perceived noise level would be reduced to 80 dBA.

25/1/2019, · Indeed, the highest rated ,earmuffs, in this review have an ,SNR, of 37 (and an NRR of “only” 31). The ,SNR, number is not what you want if you are in the U.S. and it is used differently. If you are in the U.S., regardless of which ,earmuffs, you are buying, make sure they have an EPA label with the NRR AND a table noise attenuation data by frequency (this is what the NRR is calculated from).
Modular ,Helmets, look almost identical to full-face, but are actually a mixture of full-face and open-face, with a front chin-guard and visor that flips ,up, to expose the whole of your face. While not offering as much protection as full face due to their flip mechanisms, they still offer a large amount ,of safety, for all riders.

X series ,earmuffs, combine 3M™ Peltors™ legendary hearing protection knowledge with our most advanced technologies, creating our most comfortable, curable ,earmuff,. A broad range of protection in colour coded SNRs they make finding the correct protection level easier.
At high speed, the noise inside your ,helmet, can reach 115 decibels. And that would be the noise from the wind only. If you factor other road noises, the total noise will ,go up,.. According to studies, hearing loss starts occurring when you are exposed to a noise starting at 85 decibels. With 115 decibels and more, you can expect the hearing loss to be more common in riders.

24/8/2019, · ,SNR, is the EU standard, while NRR is the US standard. The testing procedure is slightly different between them and the calculations involved are different. Both ratings are designed to give a good estimate of real-world noise reduction in decibels when the hearing protection is fitted properly in most real-world noise environments.
