What is the use of ear muff?
Purpose. Hearing protectors are required to prevent noise induced hearing loss. Hearing protection devices reduce the noise energy reaching and causing damage to the inner ear. Ear muffs and earplugs are the most common types of PPE.
How do ear muffs work?
The head-band and outer covering is usually made from a hard thermoplastic or metal. The protection usually comes from acoustic foam – this absorbs sound waves by increasing air resistance, thus reducing the amplitude of the waves. The energy is transformed into heat.
How do earmuffs protect your ears?
Earmuffs come in many models designed to fit most people. They block out noise by completely covering the outer ear. Some earmuffs also include electronic parts to help users communicate or to block sound impulses or background noise.
What is meant by ear protection?

Why are ear muffs used for hearing protection?
Just as in ordinary ear muffs, the protection provided by electronic hearing protectors is due to the sound-blocking material in the ear cups, not the electronics. (The electronics are there to transmit and/or amplify low-level sounds so that you can still hear them.)
What kind of earmuffs do you wear to keep your ears warm?
Varieties. 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.
How are earmuffs used to control background noise?
Active earmuffs have an electronic component and microphones that allow the user to control their access to communication while attenuating background noise.
What happens when you wear earmuffs with earplugs?
Wearing earphones when the noise is reduced or not present could become quite boring. Therefore electronic ear muffs offer microphones that receive ambient sounds, which are then played back through the built-in drivers. This is an automatic system that will switch off when loudness is detected for your safety.
