What equipment should soldiers wear during training in noise-hazardous environments?

Wearing hearing protection devices in noise-hazardous environments is crucial for soldiers to safeguard their hearing. Such environments can expose individuals to levels of noise that may lead to permanent hearing loss or impairment. Hearing protection devices, such as earmuffs or earplugs, reduce the intensity of harmful noise while allowing for communication if they're designed with that capability.

In contrast, standard helmets are primarily designed to protect against impacts and ballistic threats but do not provide adequate noise protection. Communication headsets may help with communication in noisy settings but are not specifically intended to protect hearing. Night vision goggles serve a different purpose altogether, as they assist with visibility in low-light situations but do not address noise hazards at all. Overall, hearing protection devices are essential for maintaining the auditory health of soldiers in environments where noise levels are a concern.
