This report in Science Alert describes how researchers in Sweden figured out that there are three types of Type I nerve fibers in the ear. They did this using sophisticated DNA analysis techniques.
I often say that all research in a broad range of fields adds to our knowledge about noise and hearing and health, but quickly add that no new research, and no more research, is needed to know that noise causes hearing loss and non-auditory health effects including hypertension, heart disease, stroke, and death.
The scientific evidence is strong enough that there can be no rational doubt about this. And anyone who still has doubts about this can join the folks at the Heartland Institute who still don’t think the scientific evidence about cigarette smoking causing lung cancer is strong enough to be conclusive. Or the Flat Earth Society.
For the rest of us, guided by science, let’s aim to protect our ears and preserve our hearing.
