Disposable earplugs 1110 with cords 37 dB SNR (100 pairs) 3M

1100 moldable and disposable earplugs with cords 37 dB SNR (200 pairs) 3M.

The 3M 1100 (7100100637) earplugs are made from soft hypoallergenic polyurethane foam, a material that provides maximum comfort and low pressure in the ear canal.

The soft, dirt-resistant surface, thanks to a smooth and less porous surface, provides better hygiene, durability, and comfort levels.

The conical design adapts to most ear canals and facilitates the use of the plugs.

FEATURES

• The 1100 earplugs from 3MTM do not have a cord, while the 1110 earplugs from 3MTM are the previous version with a cord.
• The soft hypoallergenic foam softens with body temperature once inserted for comfortable and prolonged use.
• The slow recovery polymer foam helps achieve good acoustic properties and a seal that reduces noise.
• The conical design allows for a good fit in a wide variety of ear canals.
• The low equilibrium pressure helps reduce pressure in the ear canal.
• SNR 37 dB
• Both models are compatible with the E-A-RfitTM validation system for both ears from 3MTM.

ATTENUATION VALUES

SNR = 37dB H = 37 dB M = 34 dB L = 31 dB

Legend:

APVf (dB) = Mf – sf (dB)

Mf = mean attenuation value sf = standard deviation APVf = assumed protection value

H = high-frequency attenuation value

M = mid-frequency attenuation value

L = low-frequency attenuation value

SNR = single number rating (the value that is subtracted from the C-weighted sound pressure level, L(C), to calculate the effective A-weighted sound pressure level in the ear canal)

APPLICATIONS

Its use is suggested for lower range noise levels.
