Just a quick response here since I'm at work.
Welcome to the site though. Glad you found us.

I personally have never flown before, but for noise, my favorite approach for blocking it out has been to wear ear buds, the kind you actually insert into the ear, and listening to music. I tried noise cancelling headphones for a bit, but mine weren't the most expensive and didn't do well enough I felt. I also have tactile issues that made them bothersome to wear.

I know people who have gone both the standard ear plug route and the good over-headphone-earmuff route and found them quite useful. Ultimately, it'll be up to you to figure out which setup works best for you, but hopefully you are able to get some good ideas or suggestions. I hope things go well for you on this one. Welcome again!
