Another reason to wear Ear Plugs.
Watch this video (with headphones) and see if your hearing is where it should be. It's SO important to wear ear plugs while riding not only to preserve our hearing but our sanity as we head out on two wheels.
I learned early on that wearing ear plugs (even the cheap $0.99/100 ones) help me concentrate on the road. Minimizing distractions, isn't that one of our goals while we ride so we can focus?
I found this to be the case more so on Twisties. I could focus on my apex, entry speed, exit speed, decreasing/increasing radiuses, everything I needed to make better, smoother, faster turns.
One resource I highly recommend is Earplug Superstore. You can order a couple of sample packs which provides one of each of almost everything they sell. Some are softer than others, some are denser, squishier. One pair may feel nice while another may feel really uncomfortable. I also figured out that I can sleep in these and they help block the snoring action from my beloved groom.
I tried these two packs: (1) http://www.earplugstore.com/unfoamtrialp1.html and (2) http://www.earplugstore.com/snoring-relief-kits.html
So far, I've discovered that this type of plug fits me the best because it's squishier/lighter and more comfortable:
Howard Leight LaserLite UF Foam Ear Plugs (NRR 32)
Cost: $22 for 200 pairs!
I know it can be strange to wear ear plugs at first, but after trying a few different options, I'm sure you'll find something that works for you. Safe riding!
