2.2 Proper Insertion Technique
- With one hand, reach over your head and pull your outer ear (pinna) upward and outward. This straightens the ear canal.
- With the other hand, gently insert the rolled-down earplug into the ear canal.
- Hold the earplug in place with your finger for approximately 30-60 seconds while it expands to fill the ear canal.
- Release your ear and check the fit. The earplug should feel snug and comfortable, and noise should be noticeably reduced.
