Which of the following helps prevent hearing loss? Wearing protective earplugs when operating loud equipment.
Wearing protective goggles when operating power tools.
Regularly cleaning ears with a cotton swab.
Yawning and “popping” your ears.

wearing protective earplugs when operating loud equipment sounds the most reasonable.

Explanation:

regularly cleaning ears with a cotton swab is good for you, but I honestly don't think it could PREVENT hearing loss.

I don't think yawning and "popping" your ears is right because how could that prevent hearing loss?

And wearing protective goggles when operating power tools does not prevent hearing loss, it protects your eyes.

I wish you a good day. God bless you!
