What does double protection consist of?

Double protection refers to the use of two forms of hearing protection to provide greater attenuation of noise levels. In the context of this question, it specifically involves combining earplugs and noise muffs.

Using both earplugs and muffs together significantly reduces the risk of hearing damage in environments with high noise levels. Earplugs fit inside the ear canal and offer a certain degree of noise reduction, while noise muffs cover the entire outer ear and provide additional protection. When used together, the two modalities can create a cumulative effect that enhances overall sound dampening, thus offering an effective solution for those exposed to hazardous noise environments.

This dual approach is especially important in industrial or construction settings, where noise levels can exceed recommended exposure limits, and the risk of noise-induced hearing loss is significant. Employing both earplugs and muffs is a proactive strategy to ensure maximum hearing protection.
