From the Manufacturer

The 3M E-A-R ARC Plug Earplugs, Hearing Conservation, 370-2000 provide a choice between arc blast and continuous noise hearing protection, eliminating the need to carry two different earplugs as environmental noise conditions change. The yellow end suppresses arc blasts (loud sudden noises) with a calibrated filter that reduces it to a lower level, while still allowing workers to hear conversations, signals, warnings, or other critical sounds. The red end delivers steady 22 dB protection from continuous high noise levels that can occur from heavy equipment or power tools in use. The triple-flange tips offer fast and easy, no roll insertion. These earplugs are washable and reusable, and they come in a handy plastic carrying case.
These earplugs offer two listening modes: 1) Hear-Through Mode allows the wearer to hear normally when noise levels are below 100 dBA and provides instant attenuation of high level impulse noises like arc flash, 2) Constant Protection Mode provides constant noise reduction for continuous noise such as power tools, machinery, and other loud noise sources. The wearer changes listening modes by removing earplug then inserting the opposite end into the ear. The Noise Reduction Rating (NRR) of these earplugs is 22 dB when the red end is inserted into ears and a Noise Reduction Rating (NRR) of 0 dB (level dependent) when the yellow end is inserted into ears. The yellow end uses a patented design called Hear-Through that allow workers to still hear while wearing the earplugs. These soft polyurethane foam earplugs are test compatible with the 3M E-A-Rfit Validation System.
Not only is noise present in our daily routines and recreational activities, but millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that hearing loss afflicts 28 million Americans. About one third of those cases are at least partially attributable to noise. Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection.
