Attenuation values of all EarProtect hearing protectors

Earplugs and banded earplugs (EN 352-2)

Earmuffs (EN 352-1)

How to read the values

• SNR is a single-number rating for attenuation across all frequencies. H, M and L give the attenuation for high-, medium- and low-frequency noise (SNR and H/M/L explained).
• All values are laboratory values from the type-examination. For practice, DGUV Rule 112-194 in Germany applies deductions: 9 dB for foam earplugs, 5 dB for pre-moulded earplugs, banded earplugs and earmuffs; the UK HSE recommends a 4 dB real-world deduction.
• More attenuation is not automatically better: 70 to 80 dB(A) should reach the ear (overprotection).
• The hearing protection finder shows the right value for your workplace. Typical levels are in the noise levels table.

All values come from EU type-examination certificates under Module B of Regulation (EU) 2016/425, issued by SATRA Technology Europe (identification number 2777). Data sheets, user instructions and declarations of conformity are under Data sheets.
