All of our New Line Plugfones, as well as our Plugfones Yellow, are ANSI-tested earplugs and when used as directed, offer a Noise Reduction Rating (NRR) of 25 dB. In some extremely loud environments, there may be a requirement for a volume delimiter to be used in conjunction with Plugfones depending on noise levels.
What Is A Noise Reduction Rating?
An official Noise Reduction Rating (NRR) is a certification of the number of decibels that a noise level can be reduced by the proper application of the device or item being tested. This rating is provided so that the consumer can choose a device that will provide adequate hearing loss protection given their normal activities and usage.
If you were running a bulldozer with an average noise level of 100 dB–without hearing loss protection- you could run into trouble very quickly. If we use our Yellow Plugfones (or other Plugfones) correctly the 100 dB noise level is reduced to 91 dB which is about the same level as an electric shaver or TV.
