Frequently Asked Questions
Even with earplugs, it’s common to hear sounds still because earplugs are designed to reduce, not eliminate, noise. Earplugs significantly lower the volume of external noise but do not create an utterly soundproof barrier. This residual hearing allows for awareness of the environment and is particularly important for safety reasons, enabling the wearer to hear alarms, sirens, or other vital signals. The effectiveness of earplugs depends on their Noise Reduction Rating (NRR), the correct insertion technique, and the fit in the ear canal. Even the best-fitting earplugs or those with the highest NRR cannot block all sounds completely, as some sound waves can travel through the bones in the skull to reach the inner ear. Combining earplugs with over-the-ear protection might be more effective for complete silence in extremely loud environments.
Wearing earplugs correctly is essential to ensure they provide the maximum protection for your hearing. Here is a step-by-step guide to wearing earplugs properly:
