Summary: Protecting
ears from noise.
Ear protection
is personal protective equipment (PPE) designed to reduce the intensity of
sound reaching the ears, thereby preventing noise-induced hearing loss.
Excessive noise exposure can cause permanent damage to the delicate structures
of the inner ear, leading to hearing impairment. Ear protection comes in
various forms, including earplugs, which are inserted into the ear canal to
create a seal, and earmuffs, which fit over the ears and create an acoustic
barrier. The effectiveness of ear protection is measured by its noise reduction
rating (NRR), indicating the degree to which it reduces sound levels. Proper
selection and consistent use of ear protection are crucial in noisy work
environments, such as construction sites, factories, and airports, to safeguard
workers' hearing health.
