korvatulppa

Korvatulppa is a Finnish word that translates to "earplug" in English. Earplugs are devices inserted into the ear canal to block or reduce the level of sound entering the ear. They are commonly used to protect hearing from loud noises, such as those found at concerts, construction sites, or while operating machinery. They can also be used to aid sleep by blocking out distracting sounds.

There are several types of earplugs available. Disposable foam earplugs are inexpensive and widely available, expanding to fill the ear canal once inserted. Reusable silicone or wax earplugs offer a more custom fit and can be washed and reused. Custom-molded earplugs, made from impressions of a person's ear canal, provide the highest level of comfort and noise reduction. The effectiveness of earplugs is measured by their Noise Reduction Rating (NRR), which indicates the amount of sound reduction in decibels. Proper insertion is crucial for achieving the stated NRR and for maximum hearing protection.
