Protect Your Hearing!
Hearing loss affects over 15% of American adults either through genetics, age, or noise. Since we can’t change our genes or reverse time the only thing we can do to prevent hearing loss is to protect our ears. Loud noises, along with prolonged exposure, damage the cells within our ears. When damaged, these cells cannot process sound waves leading to partial or complete hearing loss. Loud working environments such as factories, airports, and construction sites require hearing protection ranging from in ear earplugs to earmuffs that cover the entire ear. Even everyday noises can affect us, unaware of the potential damage. Playing loud music, using in ear headphones, and even mowing the lawn, can affect hearing. In this experiment students will design a hearing protection device to eliminate as much noise as possible.
Students will design a hearing protection device to protect their ears from loud noises.
