The 3M E-A-R Classic Soft Earplugs are made of a proprietary thermal-reactive foam that starts out firm for easy fitting in the ears, but then softens from body heat for a comfortable fit that customizes to the unique shape of each ear. Bright yellow color allows supervisors to conduct a quick visual hearing protection compliance check. Each pair of earplugs come in a poly bag to keep them clean prior to use. Recommended applications include chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding. These earplugs are commonly used in the following industries: agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas and pharmaceuticals. These earplugs have a Noise Reduction Rating (NRR) of 31 dB, CSA Class AL. However, research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit, earplug fitting skill and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection. 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.
