What is NRR dB rating?
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.
Is NRR same as dB?
Noise Reduction Rating (NRR) is a unit of measurement used to determine the effectiveness of hearing protection devices to decrease sound exposure within a given working environment.

What is the best dB for noise reduction?
NRR Ratings
The highest NRR rating for earplugs is 33, and the highest available NRR rating for earmuffs is 31. These values reflect the level of noise protection available for each device when worn alone.
Is NRR 31 dB good?
On one extreme, if you are shooting at an indoor range with a lot of echo and you have some hearing loss already and want to protect what you have, you will want to find the highest NRR rating device that you like. Something with an NRR 29, 30 or 31 would be safest.
What is a good dB rating for ear protection?
85 Decibels (dB) – the “Action Level” where hearing protection is required. 90 dB – the OSHA, 8 hour average exposure limit. 100 dB – exposures longer than 15 minutes are not recommended. 110 dB – regular exposure of more than 1 minute risks permanent hearing loss.
Is NRR 22 good enough for shooting?
The majority of firearm calibers fire at 140 dB or more. For this reason, ear protection is essential when shooting. To bring down the noise to a level that is safe and comfortable, you need hearing protection that has an NRR rating of 22 or greater.
Is a lower NRR rating better?
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.
What is considered loud in dB?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
What is NRR and SNR?
While the NRR is the standard for hearing protection attenuation across North America, the Single Number Rating (SNR) is the EU’s standard. Like the NRR, the SNR gives you an estimate of the level of noise reduction that a hearing protection device can provide.
What is the NRR of foam ear plugs?
The effectiveness of earplugs is specified by a Noise Reduction Rating (NRR) typically ranging from 15-35 decibels.
What does NRR 33 mean?
This means that if you are at a rock concert with a level of noise exposure at 100 dB and you are wearing a hearing protector with an NRR 33 dB, your new level of noise exposure is 87 dB. If you are wearing a product with an NRR of 27 it would deduct 10 decibels (27-7/2=10).
How many dB do foam earplugs reduce?
15 to 30 decibels
Wearing earplugs or earmuffs is effective, reducing noise by about 15 to 30 decibels if worn correctly, according to the University of Rochester Medical Center.
