Farmers have a higher than average rate of hearing loss.
It comes from working around loud machinery, livestock in enclosed areas, or power tools. Exposure to these noises day after day over a lifetime can lead to significant hearing loss unless you protect your ears. If you have to shout to be heard by someone three feet away, you may need hearing protection. This protection could be something as simple as wearing ear plugs whenever you work in the barn or on a tractor without a cab. Check out hearing protection at your local farm supply store.
