17 dB Banded Hearing Protection

These 3M 321-2101 banded ear plugs provide a Noise Reduction Rating of 17 dB. Soft polyurethane foam pods sit at the end of a flexible blue band. The reusable design is supplied as wrapped pairs in a bulk box. They meet the ANSI S3.19-1974 standard for hearing protection.

Suitable for intermittent noise exposure

Workers who need to remove and replace hearing protection frequently will find the band convenient. The pod shape fits medium ear canals and the metal-detectable feature is absent. Buyers requiring higher attenuation for very loud environments should consider alternatives with a greater NRR.

NRR 17 dB defines the protection level

The single figure that determines suitability is the 17 dB Noise Reduction Rating. It indicates the reduction achieved under laboratory testing to ANSI S3.19-1974. Match this value to your workplace noise assessment to confirm adequate protection.

Questions about this item

Should I choose the single pair or a bulk box of the 321-2101 banded ear plugs?

The 321-2101 is supplied as one pair per package in a bulk box of wrapped pairs.

What does the 17 dB NRR mean when I wear these pods on site?

The 17 dB Noise Reduction Rating indicates the average attenuation measured under ANSI S3.19-1974 test conditions; actual protection depends on fit and wear time.

How does the ANSI S3.19-1974 standard limit the performance claim for these plugs?

The standard defines the laboratory method used to derive the 17 dB NRR; it does not guarantee the same reduction in every real-world noise environment.
