Mega Bullet™ Disposable Soft Polyurethane Foam Ear Plugs, Uncorded 100 Pairs Per Box - NRR 32 -267-HPF210

Our soft polyurethane foam has a unique cellular structure that allows for slow expansion to perfectly fit the size and form of the ear canal, with a sealed surface that prevents foreign bodies from penetrating. The material provides high and immediate noise reduction.

Uncorded: The most economical option, and mainly for one time use. Also practical in areas where a cord may be hazardous.

Tapered: Fits to the natural contour of the ear canal.

Features

  • Innovative “T-shape” makes removal simple
  • NRR 32 protection
  • Consistent cellular structure for optimal expansion recovery time for a custom, uniform fit
  • Smooth closed cell outer layer that prevents debris build-up
  • Soft and comfortable PowerSoft™ foam supports long term comfort

Understanding the Noise Reduction Rating.

The level of noise entering a person’s ear, when hearing protection is worn as directed, is closely approximated by the difference between the A-weighted environmental level and the NRR.

Example

  1. The environmental noise level at the ear is 92 dB(A)
  2. The NRR is 32 decibels (dB)
  3. The level of noise entering the ear is approximately equal to 60 dB(A)

Noise Reduction Ratings

Understanding NRRs

The Noise Reduction Rating (NRR) measures how much a hearing protection device (HPD) reduces sound levels in a lab test. However, it doesn't consider the loss of protection when HPDs aren't fitted properly or worn for the entire exposure time. For many users, the NRR printed on the label overestimates the actual protection in real-world situations.

The NRR on the label is based on a lab test where the HPD is fitted on 10 different people by the tester. This method often results in high ratings, up to 33 dB. Research shows that these ratings are higher than what many users actually experience. Therefore, it's recommended to adjust the NRR before estimating the HPD's effectiveness.

To adjust the NRR:

  1. Subtract 7 dB if noise is measured on the A-weighted decibel scale (dBA).
  2. Divide the result by 2. This is called "derating".

In the future, a new method called the NRR (SF), or subject fit, will be used. In this method, subjects fit their own HPD according to the manufacturer's instructions. The NRR (SF) is usually a lower rating than the current NRR, and it may be closer to the actual performance of the HPD.
