The HEAROS Rock’N Roll Series has a certified Noise Reduction Rating (NRR) of 27 decibels. So what does that mean to you? In simple terms, like the Sun Protection Factor (SPF) of sun tan lotions, where the higher the number, the better the protection, the Noise Reduction Rating provides an indicator of the level of protection one can reasonably expect to derive when wearing an ear plug properly. Plainly stated, the higher the NRR, the higher the protection. This ear plug offers a certified Noise Reduction Rating of 27 decibels which is among the highest of any reusable ear plug.
