workers face high levels of noise daily. To protect hearing, factories use safety earmuffs and earplugs. Both provide essential protection, but they differ in effectiveness and comfort. The Noise Reduction Rating (NRR) is a key factor in choosing between safety earmuffs and earplugs. This blog explores the NRR of safety earmuffs and earplugs produced\u00a0in factories across China. What is NRR? The NRR measures how much noise protection a hearing device provides. A higher NRR means greater protection. Factories must select hearing protection based on their noise environment and safety standards. Safety earmuffs and earplugs are commonly used, but each has different advantages and limitations when it comes to NRR.
