Скачать или смотреть Are Noise Cancelling Earmuffs Good For Power Tools?

If you frequently use power tools, protecting your hearing is paramount. But when it comes to noise reduction, are noise-cancelling earmuffs actually effective and safe for this specific application? This video delves into the science and practicalities to give you a clear answer.

Here's what you need to know about earmuffs for power tools:
► Passive noise-reducing earmuffs are generally recommended over active noise-cancelling (ANC) earmuffs for loud, constant power tool noise.
► Active Noise-Cancelling (ANC) technology is primarily designed to cancel out low-frequency, steady background hums, not the sudden, high-frequency, impact noises of power tools.
► Relying solely on ANC for power tools can give a false sense of security, as crucial damaging frequencies might still penetrate.
► Always check the Noise Reduction Rating (NRR) when choosing hearing protection for power tools, as a higher NRR indicates better protection.
► Proper fit and consistent use of appropriate hearing protection are key to preventing permanent hearing damage from power tool use.
