The attenuation depends on the type of material used for the hearing protector and the filter that is used. The attenuation therefore depends on the type of Pluggerz Custom-Fit, so the Road and the Hobby made from the same material and fitted with the same filter have the same attenuation values.

The table above shows the attenuation values for flexible (soft) Pluggerz Custom-Fit hearing protectors with the different filters. The second table shows the attenuation values for the hard Pluggerz Custom-Fit. The attenuation values for the Pluggerz Uni-Fit are shown in the last table. Pluggerz Uni-Fit are all supplied with a 'fixed' filter, so the attenuation for these depends on the type of Pluggerz Uni-Fit.

  • For predominantly low frequency noise environments in which the difference in the measured C-weighted and A-weighted noise levels (dBC—dBA) exceeds 3 dB, the user is directed to the enclosed graph of the variability of noise reduction with noise spectra to determine the level of protection.
  • Improper fit or improper use of this device will decrease noise reduction effectiveness and increase the risk of hearing damage.
  • When this device is worn as directed, the level of noise entering a person's ear is approximated by the differences between the A-weighted environmental noise level and the lesser and greater NRRs.
