What you will learn
Earplugs are small in size and fit and block the ear canal. They are made from a wide range of materials such as: soft plastic, silicone, PVC, and polyurethane.
The cool thing about them is that you can use them in a wide range of noise environments. When you wear them correctly, they provide good sound attenuation.
When you wear them, you don’t have to worry about them getting in the way when you will wear a helmet or any form of eye protection.
There are many types of earplugs on the market that you can go for, with the most common being:
Soft foam earplugs: They fit into the ear canal and often expand after rolling and inserted them to fit and plug your ear canal.
The cool thing about them is that they are inexpensive, disposable, and ideal for use in areas of prolonged, continuous, high noise levels, such as at the construction site.
In most cases, these earplugs have higher NRRs.
Soft, flexible inserts: They are made from plastic, silicone, or rubber.
When you wear them, they perfectly fit and block your ear canal.
They are characterized by circular molded ridges (flanges) that aid in keeping them in place.
The cool thing about the hearing protectors is that they are easier to insert and often reusable and washable.
Due to this, they are more hygienic.
Unlike the previous ones, these have a lower NRR and are ideal for use in intermittent environments, lower noise levels, such as when you have a woodworking project.
They are also an ideal choice for you if you have problems rolling a foam rubber earplug.
Banded semi-inserts: They are custom-molded to fit an individual’s ear.
Just like the banded semi-inserts, these earplugs are easy to insert and ideal for use in areas of intermittent noise protection.
They are ideal for you if you have issues inserting the other types of earplugs.
To get the most from these units, you should ensure that the mold is a good fit.
When buying them, you should note that they tend to be more expensive than the other hearing devices in the market, but they are reusable and tend to last longer, thus you end up getting more value for your money.
How to wear the earplug
You should start by washing your hands and inspect the earplug.
You should then roll it between your fingers or across your palm.
After this, pull your ear outward and upward. Finally, insert the earplug and hold it in place until it expands.

Also known as ear defenders, earmuffs are hard plastic cups that fit your ear tightly, thus sealing the air canal.
The units surround your ears and are often sealed to your head using cushion seals.
The earmuffs have several great features that make them more attractive than earplugs.
They are more durable, easier to use, and provide better protection in certain conditions.
To wear the units, you should start by inspecting them for stiffness, tears, cracks, and other signs of wear.
You should push your hair away from the ear, then center the band and ensure a tight seal over your ears.
You should adjust the band as you feel comfortable.

At first look, canal caps look like a combination of headphones for mowing and earplugs, but they don’t provide as much protection as either.
The caps feature rounded heads that cover the entire entrance of the ear canal.
