Disposable Foam Ear Plugs, NRR 29, for Drilling, Grinding, Machining, Sawing, Sanding, Welding

More than 40 years ago, the 3M E-A-R Classic Ear Plugs, the world's first foam ear plug, revolutionized hearing protection in the workplace and has remained one of the most widely used earplugs in the world to this day. These earplugs are constructed from slow-recovery, low-pressure foam, fitting snugly to create a noise barrier that helps protect hearing from loud sounds.

The earplugs are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear. Their bright yellow color allows supervisors to conduct quick visual hearing protection compliance checks. These earplugs are recommended for a variety of applications, including 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 industries such as agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals. They have a Noise Reduction Rating (NRR) of 29 dB, CSA Class AL, and can be fit tested with the 3M E-A-Rfit Validation System. The moisture resistance of these earplugs helps maintain a consistent fit, even in humid environments.

Noise is present in our daily routines, and millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high-frequency hearing loss due to exposure to noise at work or during leisure activities. Hearing loss due to noise is almost entirely preventable by consistent use of hearing protection.

3M strongly recommends fit testing of hearing protectors, as research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in hearing protector fit, fitting skill, and motivation of the user. If the NRR is used, 3M recommends that it be reduced by 50% or in accordance with applicable regulations.
