Earwax is a natural wax-like substance produced in the ear canal of humans and other mammals. It acts as a protective agent, trapping dust and other small particles and preventing them from reaching, and potentially damaging, the eardrum. In addition, EARWAX also helps to keep the skin of the ear canal lubricated and moist. Sound blockers are materials that absorb or deflect sound waves, reducing the amount of sound that passes through them. EARWAX can act as a sound blocker, helping to reduce the amount of sound that reaches the eardrum.
