Reddit mentions of Howard Leight MAX-1 Foam Ear Plugs Uncorded, 20 Piece

I had an MRI and they gave me these ear plugs. They're better than my noise canceling ear buds, but don't cut out all the noise. They're pleasant, sometimes I even wear them to the store, driving, or just around the house. Amazing how cutting out the white noise helps me focus on just about everything. Even making morning coffee. Or maybe a different way of looking at it is how distracting even the tiniest of sounds are. I seem to want to identify every little noise I hear, and it's nice to let that go for a bit. Anyways, they're awesome, as long as you DGAF about wearing orange ear plugs in public. I bet you could find beige ones.

Also have you heard this ted talk? She talks a little bit about how typical classrooms and work environments are open floorplans, and how detrimental that is to introverts and a lot of creative types. I bet she goes more into it in her book, Quiet.

These are the best I've found. Only my wife's most vigorous snoring purring is audible, and barely so.

Since your case of tinnitus seems to have been induced by a concert, it's most likely caused by damage to your inner ear from exposure to loud sounds (although only an ENT can determine this with any real certainty). As a result, you can safely expect that more exposure to loud sound will worsen your tinnitus, although how much it worsens can vary a fair bit depending on things like how bad your existing case is, how loud things are, etc. If you wear good ear plugs throughout, though, you'll probably be OK.

Any prolonged exposure to sound over 90dB is going to cause at least some additional hearing loss (and if you already have tinnitus, that often means worse tinnitus as well), and your typical concert will clock-in around 120dB+ or so if you're near the stage. Most mid/high-quality earplugs have a Noise Reduction Rating (NRR) of ~30dB or so, and as a result they'd do a good job of protecting you from further harm provided you keep them in and don't get too close to the speakers. Check the NRR on any earplugs you buy (it should be on the package)--ones in the 29dB range will be louder at the expense of greater risk of worsening your tinnitus, while anything with an NRR above 30dB (like these) will keep you well protected from any extra risk under normal circumstances. Anything significantly lower than an NRR of 30dB will most likely be inadequate.

EDIT: A festival can potentially be a little quieter than an indoor concert (it's easier to still enjoy the music while at a fair distance from the stage), but not by much and they're still well above the 90dB mark--you might be able to get away with using lighter ear plugs in this environment, but should consider just bringing an assortment so you can adjust your noise dampening to various performances--you want to keep things as close to 90dB or lower as possible (use charts like this, this or this to get a [very] rough idea of how loud that 90dB limit is). Judging loudness in a loud environment is difficult, so always err on the side of caution.

try other types and brands, i went through close to 20 different kinds until i found ones that work with my anatomy, which incidentally were the orange max1 reusables that bell out. Having that extra wide end is what made all the difference, for me anyway. Another trick I discovered is that putting a few drops of water on the earplug and wetting your ear canal helps with insertion and creates a perfect seal. I always carry bottled water on the bike, so it's not very much of a hassle. people do sometimes give me weird looks when i give myself what looks like a wet willie, but hey hearing loss is no fun.

I've tried a bunch and personally these keep out sound better for my ears, I think because of the flare at the end of them: http://www.amazon.com/Howard-Leight-MAX-1-plugs-Uncorded/dp/B0033YLEGO/ref=sr_1_4?s=hpc&ie=UTF8&qid=1394025495&sr=1-4&keywords=33+nrr

These:

Are absolute life savers. They block out ALL noise for sleep, you just twist them thin and stick them in and they expand to create a seal. No noise at all.

I have used many different foam earplugs. I like these the best.

Personally, I'm fine with ear plugs (reduce wind noise damage), but at one time looked into bluetooth setups like a Sena SMH10 -- but doing the math -- $170 + increased risk of being distracted as new rider vs. $0.10 ear plugs + reduced wind noise at speed + reducing risk of tinnitus -- I went for the ear plugs.

YMMV.

Problem solved
