What is the potential risk of using improperly fitted earplugs?

Using improperly fitted earplugs can significantly compromise their effectiveness in protecting against harmful noise levels. When earplugs do not fit properly, they cannot create a proper seal in the ear canal, which is essential for blocking out excessive noise. This reduced noise attenuation means that the individual is exposed to higher sound levels, which can lead to noise-induced hearing loss over time. Additionally, without the proper fit, the earplugs may not stay in place or may cause discomfort, leading the wearer to remove them and further increase their risk.

The other options illustrate benefits that do not occur with poorly fitted earplugs. For instance, increased comfort is typically associated with a proper fit, not improper fitting. Similarly, enhanced clarity of sound is not a goal of earplugs; rather, the primary purpose is to reduce sound levels for safety. Finally, while earplugs may vary in lifespan depending on their material and usage, a poor fit does not contribute to a longer lifespan but can result in less effective use and potential replacement needs. Thus, the focus on appropriate fitting is critical to ensure both comfort and protective efficacy.
