That's a helpful video, Steve. I have a sister who's an audiologist and she taught me these techniques years ago.
I use disposable plugs and "earmuffs" together whenever possible. That works for me everywhere but the range. For that situation, I use custom moulded plugs. We get a fellow to come to our gun club a couple times a year to do his thing.
I can remember a time a few decades ago when a guy using hearing protection, at the range or on the job, got razzed about being a sissy. Thank goodness times have changed.
We went to a Neil Diamond concert a few weeks ago, and after 2 songs I had foam plugs in. It was that or leave. It was physically painful for me. I left a nephew's wedding reception a few months back because I couldn't tolerate the DJ's volume. My grandkids crank the volume on their earbuds, and they'll be deaf sooner than I was. We've done education on smoking, texting, sex, and motorcycle helmets. Could hearing protection be next?
Seems people will pay hundreds of dollars for great concert seats only to lose their hearing.
