Earplugs are commonly used by people who work in noisy environments such as construction sites, factories, and airports. They are also used by musicians and concert-goers to protect their hearing from loud music. Additionally, earplugs are used by swimmers and divers to prevent water from entering the ear canal and causing infections.
Silicone earplugs are another popular option, particularly for swimming and water activities. They are reusable and can be easily molded to fit the shape of the ear canal, providing a comfortable and secure fit.
