EARPLUGS WARNINGS & TESTING
IMPROPER FITTING OR MISUSE WILL REDUCE THE EFFECTIVENESS OF EARPLUGS/EARPIECES AND COULD RESULT IN HEARING LOSS OR INJURY
The molding process involves heating your molds and forming them to your ears. DO NOT PLACE THE HOT MOLD INTO YOUR EAR. Wait until the mold is warm and pliable before inserting it into the ear. Wear hearing protection at all times that you are exposed to loud noise. Test thoroughly in progressively louder environments. Do not enter a loud environment right away. Start in a quiet, low noise environment and slowly increase your noise exposure to make sure your earplugs are providing adequate protection. You should be able to hear your voice clearly, but at a reduced volume, and the noises around you should not sound as loud.
If at any time you feel your hearing protection is not providing adequate protection, remove yourself from the loud environment immediately.
Remove any piercings in the concha of the ear as the piercings may become fixed to the molding material.
It is important that the ear tip seals correctly to achieve the designed attenuation level.
Check that the foam and/or silicone ear-canal tips are securely attached to the EZ shape custom molded earpiece before every use. Remove the earplugs/earpieces slowly and gradually break the seal. Rapid removal may damage the eardrum.
Use only as directed. If misused (by failure to use as directed), the ear canal tip may become lodged in the ear, which requires removal by an Ear, Nose, and Throat Doctor ONLY.
We advise that you read the fitting instructions carefully before placing in your ear. Molds must be molded properly for maximum effectiveness.
CAUTION: CHOKING HAZARD
Keep away from children and pets. Parts are non-toxic but may interfere with breathing if caught in the windpipe.
NRR & INDIVIDUAL USER
The EPA has selected the Noise Reduction Rating as the descriptor of hearing protector effectiveness to be utilized on the labels required by U.S. EPA Regulation 40 CFR Part 211 Subpart B. Decibullz makes no warranties as to the suitability of NRR as a measure of the actual protection afforded to the individual user.
Excessive heat can deform the earplugs/earpieces. Do not leave in a hot car, direct sunlight, or anywhere with excessive heat. Exposing them to temperatures above 120°F/49°C could cause the EZ shape custom molds to melt and your Decibullz can become damaged.
TESTING YOUR EARPLUGS
IMPROPER FITTING OR MISUSE WILL REDUCE THE EFFECTIVENESS OF EARPLUGS AND COULD RESULT IN HEARING LOSS OR INJURY
Test your earplugs in progressively louder environments. You can do this by gradually increasing your noise exposure. Another way to test your earplugs is to talk out loud. While wearing your earplugs, the sound of your own voice should become deeper, hollow, or muffled in BOTH ears. If the change is not in both ears, or there is no change at all, you have not achieved a secure seal and you will need to remold your earpieces or contact Decibullz customer support. Keep in mind that you will still hear some surrounding frequencies and noises while wearing your Decibullz earplugs. However, the surrounding noise should be muffled and you should always feel a secure seal.
You can also check the fit once you are done with the molding process by cupping your hands tightly over your ears. If the surrounding sounds seem more muffled with your hands over your ears, then the earplugs might not have the secure seal that is needed. Try the various sizes and combinations of tips to improve the seal of your earplug or you might need to remold to obtain the desired fit and seal.
