Are ear muffs as effective as ear plugs?

For ear protection in high noise environments, ear plugs can offer a more complete level of noise reduction. However, ear muffs have advantages in that they don't have to be fit inside the ear, and so can be more comfortable, economic and hygienic.


Why are ear defenders necessary?

Hearing protection is designed to protect the user from extreme noise levels. The padding of the cushion is made from a type of acoustic foam that absorbs the waves to stop them from reaching the eardrum.

Some everyday tasks can damage your hearing and can have a catastrophic effect. So it's important to protect yourself of task/activities such as mowing the lawn.
