Highest NRR Earplugs

For the noisiest environments only the highest level of protection will do. That means getting the highest Noise Reduction Rating (NRR) you can.

What is NRR?

NRR is measured in decibels (db) and tells you how much the hearing protection is lowering the sound level prior to it reaching your ears. So for example if you are at a concert that has an average noise level of 100db and you are wearing hearing protection with 30db then the noise level reaching your ears would be 70db.

Foam ear plugs are the most cost effective and easiest way to protect your hearing. These earplugs all boast an NRR of at least 32 dB, which will be sufficient for most situations.
