Which items are considered forms of hearing protection?

Hearing protection is crucial in environments where noise levels can cause hearing damage or impairment. Earplugs and headsets are specifically designed to mitigate sound exposure. Earplugs block or attenuate sound waves from entering the ear canal, thus reducing the overall volume that reaches the eardrum. On the other hand, headsets may integrate features that not only provide noise reduction but also allow for communication without the need to remove ear protection, making them essential for aircrew operations where situational awareness and communication are vital.

Other options mentioned do not serve the purpose of protecting hearing. Foam padding and helmet liners are geared more toward comfort and impact protection rather than auditory safety. Eye goggles and face shields focus on protecting the eyes and face from hazards, and hard hats along with safety shoes are protective gear against physical and environmental dangers rather than noise. Therefore, earplugs and headsets are uniquely tailored for hearing protection.
