Korvatulppia

Korvatulppia, or earplugs, are small devices designed to seal the ear canal in order to reduce noise exposure or prevent water from entering the ear. They are commonly used to protect hearing in loud environments, aid sleep, or prevent water ingress during swimming.

Earplugs come in several basic types and materials. Foam earplugs are usually disposable and expand to fill the ear canal. Silicone earplugs are often reusable and come in multiple shapes, including molded or wraparound designs. There are also waxed or moldable variants that can be formed to fit the ear. Custom-fitted earplugs are made by an audiologist or specialized technician to match the shape of an individual’s ear.

Usage and safety considerations are important for effectiveness and comfort. For foam plugs, roll the tip between fingers to compress, insert into the ear canal, and hold for several seconds as it expands. For silicone or moldable plugs, follow the product instructions. Clean hands and dry ears help prevent infection. Do not insert plugs too deeply, and discontinue use if there is pain, discomfort, or persistent wax buildup. Reusable plugs should be cleaned regularly and replaced when worn or damaged; avoid sharing.

Effectiveness varies by product, with measured noise attenuation depending on fit and design. Earplugs are widely used in occupational settings, for sleep, or during activities involving loud music or water exposure. They are part of general ear health measures and should be used according to manufacturer guidelines.
