What does NRR 32 mean?

Noise Reduction Rating (NRR) is a measure of the effectiveness of a hearing protection device to reduce noise levels. Higher values indicate greater noise reduction. NRR values range up to approximately 30 dB. To the right is an example of the EPA label for a headset with an NRR of 33 dB.

What is a good NRR rating for outdoor shooting?

A great rule of thumb when considering what Noise Reduction Rating (NRR) is best for shooting -- start by aiming for a protection level of at least 25 decibels. If your hearing protection has at least a 25 NRR and doesn't sacrifice comfort or compromise your ability to communicate with others, you'll be in great shape.

Are ear plugs good enough for shooting?

Considering the likelihood of incurring a NIHL, NIOSH recommends that hunters and shooters use double hearing protection every time a weapon is fired. Double protection involves wearing both earplugs and earmuffs. The best combination is a deeply-inserted foam earplug and a well-seated earmuff.
