Noise Reduction Ratio Calculation at Stacy Mistretta blog

Noise Reduction Ratio Calculation. To begin, the nrr is not as precise as you might imagine it is. Rather than a strictly empirical and invariable calculation, the nrr is more. But it’s a bit more complicated than that. Check hearing protection performance by estimating the sound level at the ear when wearing muffs or ear plugs. In simple terms, it measures the ppe’s noise attenuation ability, or how well it reduces the perceived loudness of a sound. For hearing protection devices, osha introduced the noise reduction rating (nrr) system in 1979. The nrr calculation helps estimate the actual noise exposure level when using hearing protection.
