Protetores auriculares 3M 1271C protetores auriculares de espuma NRR 27 dB, reutilizáveis com cordão, par

3M 1271C foam earplugs are corded, reusable foam plugs engineered to reduce ambient noise with a Noise Reduction Rating (NRR) of 27 dB. Designed to fit into the ear canal, these earplugs provide practical hearing protection for environments with elevated sound levels. Their compact shape and soft foam material allow for straightforward insertion and removal while the attached cord keeps the pair together for convenience during intermittent use.

Advantages

These corded foam earplugs combine a high attenuation level for foam-type protectors with the convenience of a reusable design. The soft compressible foam conforms to the ear canal for a secure fit and consistent noise reduction. The cord helps prevent loss and enables quick hanging around the neck when protection is not required, making them suitable for tasks that require frequent donning and doffing. The product is lightweight and portable, allowing easy storage and handling on job sites or in transit.

How to use

Compress the foam tip between fingers, gently insert the tapered end into the ear canal, and hold in place until the foam expands to create a seal. Ensure the cord is positioned outside the ear and drapes comfortably when in use. Remove by slowly twisting and pulling the plug outward to avoid abrupt extraction. Regularly inspect the plugs for dirt, wear, or loss of compressibility and replace them when performance is compromised.

Recommendations

Use these earplugs in environments where a 27 dB NRR is appropriate for hearing protection. Clean reusable foam plugs according to manufacturer guidelines and store them in a dry, clean case when not in use. Do not force insertion; if a proper seal cannot be achieved, consider alternative sizes or protector types. Replace the plugs when foam no longer recovers or shows visible damage.
