Alpine FlyFit Earplugs for Flying
Enjoy Your Flight More Comfortably
Product Description and Intended Use
The Alpine FlyFit hearing protector is designed to shield the wearer from hazardous noise levels and painful pressure differences experienced during flights. It is crucial that the user ensures the earplugs are fitted, adjusted, and maintained according to the instructions provided in this manual. Any other uses are not intended and are therefore prohibited.
How to Use
Always wear the earplugs without interruption when in a noisy environment. To insert, gently pull your ear upwards and use your other hand to insert the earplug into the ear until it fits snugly. Do not insert the earplug too deep into the ear. Improper fit, incorrect use, or failure to follow these instructions will reduce the noise reduction effectiveness, increase the risk of hearing damage, and shorten the lifespan of the reusable earplugs.
Care and Maintenance
Alpine Hearing Protection is not liable for any damage arising from misuse. Regularly check the working order of the earplugs and store them in their original, clean packaging. Clean the earplugs regularly with mild soap and lukewarm water (max 37°C / 99°F). Dry them thoroughly after cleaning. The reusable earplugs can be used approximately 100 times.
Important Safety Information
Sudden or rapid removal of hearing protection may cause damage to the eardrum. Do not remove plugs from the ear by pulling the connecting cord. Do not use a connecting cord if there is a chance of it getting entangled.
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 Noise Reduction Ratings (NRRs).
Caution: For environments with predominantly low-frequency noise, where the difference between the measured C-weighted and A-weighted noise levels (dBC-dBA) exceeds 3 dB, refer to the enclosed graph for variability of noise reduction with noise spectra to determine the level of protection.
This product may be adversely affected by certain chemical substances. Further information should be sought from the manufacturer.
Technical Data and Certification
Noise Reduction Rating (NRR)
The Noise Reduction Rating shows the range of protection expected from this protector in normal usage. The lower number represents the protection achievable by most users (80%), while the higher number is achievable by a few motivated, proficient users (20%). Higher numbers indicate greater protection.
NRR = 18
