Selecting the proper earplug
Fit-testing allows a worker to try a variety of hearing protectors that may be suitable. Often, the worker’s first choice of earplugs is not the best. Here are some selection tips that have proven useful in one-on-one training.

General earplug shapes
-
Size:
Look at the ear canal opening to determine if a different size would be helpful. Women often have smaller ear canals than men. -
Shape:
Ear canal openings may appear as round, oval or a slit. A foam earplug often fills an oval or slit in the ear canal. -
Ease of insertion:
An earplug with a stem may be easier for some workers to insert.
