Which of the following is not a type of hearing protection?

Headsets are primarily designed for communication and may not provide the necessary level of noise reduction that is essential for hearing protection on a construction site. While some headsets can include sound dampening features, they are generally not classified as personal hearing protection devices like muffs or plugs, which are specifically aimed at protecting the ears from harmful noise levels.

Muffs, which cover the entire ear, and plugs that fit directly into the ear canal, are both established methods of reducing exposure to loud sounds, thus safeguarding hearing health. NRL devices, often referring to noise reduction hearing aids or similar technologies, can also help protect hearing, though they may allow certain sounds to be heard while minimizing harmful noise.

In summary, headsets are not categorized as a type of hearing protection because they serve different primary purposes, whereas muffs and plugs are specifically created for protecting against excessive noise.
