Answer 1

"Dry cotton earplugs are just as effective against noise control as expensive fitted earplugs and earmuffs" is false.

Step-by-step explanation:

Unlike earmuffs or fitted earplugs specifically created to reduce noise, dry cotton earplugs are often much less effective in reducing noise. This is because earmuffs and fitted earplugs provide a snug fit, which helps to block out noise and reduce its intensity. In contrast, cotton earplugs may not fit tightly or provide sufficient coverage, limiting their effectiveness in attenuating noise.
