PPE Type - Hearing Protection

PPE Type - Hearing Protection
 
PPE for hearing protection consists of earplugs and ear covers. Laborers who are consistently presented to commotion levels over the NIOSH proposal should be furnished hearing protection by the businesses, as they are a low-cost intervention.

 
There are mainly four Types of Earplugs for hearing protection:

• Foam earplugs, mainly made from either polyvinyl chloride (PVC) or polyurethane (PU) (memory foam), which are compressed (rolled) and put into the ear canal, where they expand to plug it
• Silicone earplugs, which are rolled into a ball and carefully molded to fit over the external portion of the ear canal
• Flanged earplugs, including most types of musicians' or 'Hi-Fi' earplugs.
• Custom molded earplugs, made from a mold of the wearer's ear and designed to precisely fit all ear canal shapes. Custom molded is further divided into laboratory-made and "formed in place"

There are mainly four Types of Earmuffs for hearing protection:

• Thermal earmuffs, worn in cold environments to keep a person's ears warm with pads of cloth or fur.
• Acoustic earmuffs, also known as ear defenders: cups lined with sound-deadening material, like thermal earmuffs and headphones in appearance, which are worn as hearing protection. These may be carried on a head-band or clipped onto the sides of a hard hat, for use on construction sites.
