👉 Earplugs are small, non-adhesive devices that protect your ears from loud noises and vibrations. They work by blocking out sound waves, reducing their intensity or causing them to vibrate less, depending on how they are worn. Earplugs can be used in many different situations, including at home, while driving, working in a noisy environment, or even during medical procedures. They are often recommended for people who have hearing loss or other conditions that make it difficult to hear clearly.
