Earplugs can be created using products from home. A bag of jumbo size cotton balls purchased at a store can be an inexpensive way to reduce noise. Cotton balls can weaken up to 10 dB of sounds, which is enough to muffle ambient noise and still permit important sounds to be heard.
Select two cotton balls from the package that are bigger than the openings of the ears. Large cotton balls, as opposed to small cotton balls, make it easier for them to be removed. This prevents cotton from getting stuck inside of the ear.
Mold an end from one of the cotton balls to the inner opening of the ear. Avoid moulding the end to a small size, as this may cause the cotton to enter into the ear canal which could cause damage and discomfort. Repeat the moulding process for the other cotton earplug.
Insert the cotton balls into the ear opening gently. Place the shaped end of the cotton ball into the ear, and twist the cotton ball into it while gently pushing in. Avoid pushing the cotton ball too much into the opening to prevent damaging the ear. Slightly spread apart the outer edge of the cotton ball to cover the entire ear opening.
Remove the cotton balls from the ears when their use is no longer needed. Slowly pull the outer end of the cotton earplug to remove them. Removing them slowly will prevent any small bits of cotton from remaining inside of the ear.
If the cotton balls are too large, a portion can be removed.
