OVERVIEW

Technical Overview of 3M E-A-R Classic Earplugs

The 3M E-A-R Classic Uncorded Earplugs (SKU: 3MS312-1201) represent the industry standard for disposable hearing protection. First introduced as the world's first foam earplug, the Classic series utilizes a proprietary slow-recovery, low-pressure foam formulation. This material is engineered to be stiff enough for easy rolling and insertion, yet it expands slowly within the ear canal to create a custom, comfortable acoustic seal. The cylindrical shape is designed to accommodate a wide range of ear canal sizes, ensuring consistent attenuation across a diverse workforce.

From a compliance and safety perspective, these earplugs offer a Noise Reduction Rating (NRR) of 29 dB and are classified as CSA Class AL. This makes them suitable for high-noise environments where significant attenuation is required to prevent noise-induced hearing loss (NIHL). The material is inherently moisture-resistant, a critical feature that prevents the plug from absorbing perspiration and swelling, which can lead to backing out or discomfort during extended shifts. Additionally, the foam is flame-resistant, providing an extra layer of safety in environments involving hot work or potential ignition sources.

The 3M E-A-R Classic is also compatible with the 3M E-A-Rfit Dual-Ear Validation System. This allows safety managers to quantitatively verify the fit and attenuation levels for individual employees, ensuring that the documented NRR is being achieved in practice. Each pair is packaged in a poly bag to maintain hygiene prior to use. This box contains 200 pairs, making it an economical solution for large teams or high-consumption areas.

FAQ

The 3M E-A-R Classic Uncorded Earplugs have a Noise Reduction Rating (NRR) of 29 dB.

No, these are disposable earplugs designed for single use. They should be discarded after use or if they become dirty or damaged.

Roll the earplug into a small, thin cylinder using your fingers. Pull your ear up and back to straighten the canal, insert the compressed plug, and hold it in place until it expands to form a seal.

The E-A-R Classic is made from moisture-resistant foam, meaning it will not absorb significant amounts of moisture or swell due to perspiration, maintaining its fit and comfort.

This specific SKU (3MS312-1201) is for uncorded earplugs.

While foam earplugs do not have a strict expiration date, they should be stored in their original packaging in a cool, dry place. Over very long periods (5+ years), the foam may lose some elasticity.

Yes, many people use the E-A-R Classic for sleeping due to their comfort and high noise blocking capabilities, although they are designed for industrial safety.

Yes, the proprietary foam material is flame-resistant, making them safer for environments with potential ignition sources.
