3M™ – Foam Earplugs – 1100, – Uncorded

Description

Features:

Soft Polyurethane Foam:

Offers comfort during extended wear.

Hypoallergenic, suitable for sensitive ears.

Smooth, Dirt-Resistant Surface: Improves hygiene by minimizing dirt accumulation.

Easy-to-Roll Down Design: Allows for quick and easy fitting.

Tapered Design: Ensures a comfortable fit in most ear canals.

Noise Reduction Rating (NRR): 29 dB (CSA Class AL): This indicates an average noise reduction of 29 decibels based on controlled laboratory testing. It’s

important to consider:

NRR Limitations: The NRR is a starting point. In real-world use, noise reduction might be less effective due to factors like proper fit and individual ear canal variations.

3M’s Recommendation: They recommend subtracting 50% from the NRR to get a more accurate estimate of noise reduction in typical use scenarios.

Possible Applications:

Shooting Sports: Provides hearing protection during target practice or gun ranges.

Loud Work Environments: Offers noise reduction in workshops, factories, or construction sites (consider the NRR limitations).

Sleeping: Can help block out noise for a quieter sleep environment.

Studying or Concentration: Helps reduce distracting noise while studying or focusing on tasks.

Additional Information:

Uncorded: This design might be preferable for activities where cords could get caught or snag (e.g., sleeping).
