I like to listen to bluegrass music in the shop. But I’m also running noisy machines in there, several of which produce sound levels of at least 85 decibels (db.), the point at which hearing damage starts to occur. So protection is a must. Earmuffs or earplugs are great for reducing noise to a safe level, but they make the Steep Canyon Rangers sound like they are playing in a steep canyon.

Recently, I found some earplugs called Sonic Defenders (, which let me enjoy my music while I protect my hearing. They don’t interfere with normal conversation or low-volume background noise such as a shop radio. You can even wear them while talking on the phone. Safe sound levels are allowed to pass through to the ear, but noise levels above 80 db. are reduced. When extra protection is needed, attached stoppers can be inserted in the sound channel.

Made from a soft polymer, Sonic Defenders can be worn all day. And, at $10 per pair, they’re as easy on the pocketbook as the ears.

For general use, foam plugs and muff works a lot better. The sonic plugs technology only kicks in when sound level are way above 80db. When sound is below 80db, the protection is rated at 9 db and 16dp (with the plug in). So, if you are sanding all day (70dp), these are not the protection you need. They come in different sizes. I think most people would feel comfortable in medium. They're cheap and kind of cool looking. I need to try them in the spray booth for 6 hours.
