Hint:
A
Show me the Answer
Correct answer is:
  • (E)  Cotton balls
Explanation:
Ear muffs block noise by covering the outer ear completely. In contrast, pre-molded plugs – which come in a variety of sizes and are constructed using silicone, rubber or plastic – plugs seal the ear canal. While fitting these plugs, one should not experience discomfort. Canal caps often resemble earplugs on a flexible plastic or metal band.
