Hearing Protection Devices
Hearing Protection Devices (HPDs) are devices designed to reduce the level of noise exposure and protect the hearing of individuals working in high noise environments. HPDs can be passive or active, and they work by either blocking the noise or reducing its intensity. Passive HPDs include earplugs and earmuffs, while active HPDs use electronic noise reduction technology to reduce the noise level. HPDs are essential in aviation, as pilots, air traffic controllers, and ground crew are exposed to high levels of noise from aircraft engines, ground support equipment, and other sources. Prolonged exposure to high noise levels can cause permanent hearing damage, making the use of HPDs crucial for protecting the hearing of aviation personnel.
