Corded reusable earplug box

CHARACTERISTICS:
Reusable TPR earplugs with fluorescent yellow nylon cord.
Thanks to the cord, the earplugs can be removed temporarily without losing them, or without having to store them.
The drawstring allows them to be hung from the neck and reattached when needed.
In addition, the fluorine yellow color allows them to be easily located.
TPR earplugs offer the advantage of being easier to fit, as well as offering a much more comfortable feel in the ear than PE foam earplugs.

APPLICATIONS:
Indicated for acoustic attenuation during works in mining, quarries, industry in general.
Overall protector attenuation: 30 dB

HOW TO USE:
1. Hold the plug between your fingers
2. Pull slightly on the top of the ear to open the ear canal.
3. With the other hand grasp the plug handle and gently push it into the canal until a good seal is achieved.
4. Once in place, try the earplugs in a noisy environment. Cover your ears with both hands, and when you remove them you shouldn''t notice a difference.
5. If the result is not correct, repeat steps 2, 3 and 4 until you see that the plugs are correctly positioned.
6. Check that the nylon cord falls naturally and does not get caught on glasses or any other obstacle.

Definitions:
Attenuation: Effective protection level.
dB: Decibel - unit of sound level measurement, which expresses the logarithmic relationship between a measured acoustic magnitude and another value of that same magnitude that is taken as a reference.
SNR (Protector Global Attenuation): Average level of protection offered by the protector considering all frequency bands between 63 Hz and 8000 Hz.
APV: Protection conferred (difference between mean attenuation and standard deviation).
H: Attenuation at high frequencies.
M: Attenuation at medium frequencies.
L: Attenuation at low frequencies.
