Dr. Daniel Fink says if you are going to do yard work, make sure to wear a pair of ear plugs if the tools you use make more noise than a rake. Ear plugs today will help you avoid hearing aids tomorrow.
A healthy diet might protect against hearing loss, but why not address and regulate the source of the problem? Noise causes hearing loss.
Disturb everyone else with your noise, but protect yourself. That seems to be the message in this report on ear plugs for motorcyclists.
