Earasers Earplugs for Musicians and Concerts
Earasers Musicians Earplugs
Whether you are a musician, attend concerts or are regularly exposed to music played at high levels, Earasers don't plug up your ears and muffle sound like conventional earplugs. Manufactured by a 57 year old hearing aid company, and developed by their lead engineer - a musician for over 35 years, Earasers filter out loud noise while still allowing you to hear at a safe, comfortable level. Protect your hearing and still maintain communication with those around you. If you enjoy going to concerts or just jamming out with the band, these earplugs will take care of your ears. Earasers are so comfortable they don't sweat, or tickle, or itch allowing you to enjoy the show for hours on end. The patented construction makes these high fidelity earplugs appear virtually invisible and help you focus your attention on the music.
Earasers can be cleaned and reused, and when the silicone tip starts to get old, they can be renewed with new sleeves.
Sizing Tips
The size of the external ear (the pinnae) rarely has anything to do with the size of the opening of the canal. Visit our instructions tab if you want more help determining your size.
Included: one pair of Earasers earplugs and a blue keychain carry case.

COMPARING SNR AND NRR RATINGS
The difference between SNR and NNR for earplugs lies in the region, standard, and method used to calculate the amount of noise reduction provided by the hearing protection. Here’s a breakdown:
🔹 SNR (Single Number Rating)
-
Used in: Europe and countries following the EN 352 standard.
-
Standard: Based on ISO 4869.
-
Purpose: Indicates the average level of noise reduction in decibels (dB) across a range of frequencies.
-
Application: To estimate actual protection, you subtract the SNR value from the noise level.
Example: 100 dB noise – 25 dB SNR = ~75 dB exposure.
🔸 NNR (Noise Reduction Rating)
-
Used in: United States, regulated by the EPA.
-
Standard: Defined by ANSI S3.19.
-
Purpose: Also measures average noise reduction in dB, but with different lab testing methods and assumptions.
-
Application: More conservative. OSHA recommends a derating:
-
Subtract 7 dB from the NNR,
-
Then reduce the result by 50% (to account for real-world use).
-
Example: NNR 30 → (30 - 7) / 2 = ~11.5 dB actual protection.

⚖️ Summary Comparison
Feature | SNR | NNR |
---|---|---|
Region | Europe | United States |
Standard | EN 352 / ISO 4869 | ANSI S3.19 |
Real-world use | Often taken as-is or with minor adjustments | Typically derated for realistic use |
Test Method | Frequency-weighted average with real-ear attenuation | Lab-based, sometimes overestimates |
Values | Typically slightly higher than NNR | Often more conservative after derating |
✅ In Practice
-
If you’re choosing earplugs internationally, don’t directly compare SNR to NNR.
-
Always apply the proper adjustment based on the regulatory body or safety guidelines for your region.
