I'm sorry to hear that they didn't help you.

Since they are high-fidelity ear plugs, they allow all sound frequencies ("noise") through, but just decrease the overall decibel level. I'm sorry if I misunderstood your original request/complaint and recommended these earplugs erroneously. Hang onto them in case you can use them once you're doing better.

If your church's band is using distortion there's nothing you can do to eliminate that and I've found that distortion will overwhelm my brain - it's a lot of frequencies to have to interpret cognitively. At least, this is what I've discovered for myself from listening to music over the last few months. Distortion is a very popular effect that is used with a LOT of music and it doesn't even have to be very obvious to the untrained ear to be there. I've discovered that listening to very "clean" and "dry" (no distortion and no effects, or very little) and very simple music taxes my brain the least. Over the last few months, I've been able to increase the complexity of music that I can enjoy. I'm still not able to listen to the music of my favorite band much at all (I avoid it like the plague most of the time because it drains all my energy quickly), because it's very complex, but I think in time, I'll be able to listen to it on a regular basis again someday.

I've actually thought a lot about this in the last couple of weeks. I recommend that you to slowly increase the kind of music you can listen to, rather than overwhelm yourself all at once. Listen to very simple and clean music for a few weeks only. Then increase the complexity of it gradually as you can. Kind of like the way people who are recovering from a concussion need to increase their activity levels. I actually think this method of listening to music might help people recovering from TBI to rehabilitate their neural pathways and make some connections there that were compromised.

I've read articles about the benefits of music-listening for people recovering from TBI.

Can you excuse yourself from the service space when the music is being played?
