Detail

Corder Earplug 304-L

Reference Number : 1000106
Model: Bilsom 304L (Corded)
SNR=33dB
Standard: CE EN 352

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

Example:
The environmental noise level as measured at the ear is 92 dBA
The NRR is 29 decibels (dB)
The level of noise entering the ear is approximately equal to 63 dBA

Caution:
For noise environments dominated by frequencies below 500Hz, the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuation noise. Consult the enclosed instructions for proper fit. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based on the attenuation against impulsive noise such as gunfire. Constant or repetitive exposure to impulsive noise may lead to serious injury, including temporary or permanent deafness. The Noise Reduction Rating (NRR) calculated from the attenuation data is 29dB. Earplugs must be properly fitted to attenuate noise effectively. Refer to instructions.
