Why Does the NRR differ from the Expected Noise Reduction?

We have had our earplugs rigorously tested at a certified psychoacoustics laboratory for performance under the EPA guidelines mandated by 40 CFR Part 211, Subpart B. For better or worse, the current EPA guidelines require that a very conservative estimate of the earplug’s decibel reduction capabilities is provided.

This estimate is called the Noise Reduction Rating (NRR) and must be prominently printed on all packaging. Since the introduction of the NRR system, there has been a lot of controversy over its accuracy. Many experts have recommended revamping to more closely reflect what a consumer will experience when using an earplug. In the meantime, until these changes take place, it is the standard in the earplug industry to advertise an earplug’s performance with a decibel rating that is higher than the NRR since that is what most consumers can realistically expect.

Therefore, per this industry standard, we have opted to advertise the expected noise reduction since our testing data shows that most Eargasm Earplugs users can realistically expect that higher threshold.
