What is the 3M™ 1310 banded earplug system and why choose it
The 3M™ 1310 banded earplug system is a semi-aural hearing protector designed to seal the entrance of the ear canal and help reduce exposure to harmful noise levels. It can be worn either under the chin (U-T-C) or behind the head (B-T-H), offering flexibility and compatibility with other personal protective equipment. With a low mass of 13 g, it provides an effective alternative to earmuffs in low to moderate noise environments, delivering efficient attenuation across all tested frequencies.
Main features
- Semi-aural banded design that seals the entrance of the ear canal to help reduce exposure to harmful noise levels.
- Dual wearing options: under the chin (U-T-C) and behind the head (B-T-H).
- SNR 24 dB in behind-the-head mode (B-T-H) and SNR 25 dB in under-the-chin mode (U-T-C).
- Lightweight alternative to earmuffs with a mass of 13 g.
- Slotted band design that distributes pressure comfortably and allows the band to flex and automatically adjust to the size and shape of the user’s head.
- Flexible band that can be worn under the chin or behind the head, enhancing compatibility with other PPE such as safety helmets.
- Ideal for intermittent use; when not in use, the band can be left easily around the neck.
- Durable, flexible band that can be washed and reused multiple times.
- Soft foam tips that provide good acoustic sealing and improved comfort.
- Replacement tips available (3M 1311).

Legend (acoustic parameters)
- ƒ: Test frequency.
- Mf: Mean attenuation value.
- Sf: Standard deviation.
- APVf (Mf – Sf): Assumed protection value.
- H: High-frequency attenuation value (predicted noise level reduction with LC:LA = -2 dB).

- L: Low-frequency attenuation value (predicted noise level reduction with LC:LA = 10 dB).
- SNR: Single Number Rating; value subtracted from the C-weighted sound pressure level (LC) to calculate the effective A-weighted sound pressure level in the ear canal.
Applications and use cases
The 3M™ 1310 banded earplug system can be used as hearing protection in low to moderate noise environments where semi-aural protection is appropriate and compatibility with other PPE, such as safety helmets, is needed. The banded, semi-aural design and lightweight construction make it particularly suitable for intermittent use throughout the workday.
FAQ
