Hearing Protection For Workers

Hearing protection for workers belongs on the everyday safety checklist, right alongside work gloves and eye protection. Around the farm, shop or jobsite, tractors, grain-handling equipment, power saws and other loud machinery can expose your ears to noise that causes permanent hearing loss over time. The risk depends on both how loud the sound is and how long you’re around it, so even a task that feels routine deserves attention. Repeated exposure to noise at or above 85 decibels can damage hearing, and louder equipment can shorten the time it takes for harm to occur. If you have to raise your voice to talk with someone an arm’s length away, take that as a warning sign—not a substitute for measuring workplace noise. Choosing hearing protection starts with identifying noisy tasks, checking exposure levels and looking for ways to reduce sound at the source. Equipment maintenance, sound barriers and less time near loud machinery can help, while properly selected earplugs or safety earmuffs add an important layer of protection. Earplugs and earmuffs offer different ways to protect hearing, and the best fit for the job depends on noise exposure, comfort and the other personal protective equipment you wear. Earplugs need to fit correctly in the ear canal, while earmuffs need a complete seal around each ear; glasses, hat edges and other gear can interfere with that seal. Follow the manufacturer’s fitting directions and check that your hearing protection works with your hard hat, safety glasses or face shield before starting work. Compare the Noise Reduction Rating, or NRR, on hearing protection labels, but keep in mind that laboratory ratings do not directly equal the reduction you’ll get on the job. A workplace noise assessment and individual fit testing can help determine whether protection is sufficient. Some high-noise tasks call for earplugs and earmuffs together, though their ratings cannot simply be added. Keep reusable hearing protection clean, inspect it regularly and replace worn components as directed. Choose protection that supports necessary communication and awareness of warning signals, and keep it in place throughout hazardous noise exposure—even during those last few minutes of cleanup.
