Ear defenders, protectors and plugs are designed to protect the ears and hearing from various types and sources of hazardous noise pollution. Using the correct type of ear defenders ensures the wearer's hearing is protected and can help to safeguard against the development of ear or hearing problems, such as tinnitus and hearing loss. When working in loud environments and industries such as factories, construction sites, and demolition work, it is part of your required PPE (personal protection equipment) to have the correct ear protection.
