How to deal with classroom sounds?

you have to learn
to deal with what we ALL have had to learn, as people across time

noise canceling headphones are nice, I have some!
but not all things are for all time

We are becoming more cut off one from another, as we sink into the isolation of our screen, and or our earbuds. The ability to endure the sounds of a human filled Environment more than just nice it is imperative

the ability to work around others is necessary, and putting it off will make you ever more isolated, than you may already feel

and yeah I hear you say

you do not yet know, what might happen

Wearing a headset with full-size ear cups with the noise-cancelling turned on will probably work. Just wave the unplugged end if he/she objects, but also let them know why you need them. A certain flicker frequency of fluorescent tubes bothers a lot of people, but they are not officially diagnosed. Send a letter to your school's head explaining what is interfering with your classroom learning experience, and ask them to correct the condition within 10 days. Make a copy for your records, send it certified mail, and keep the receipts. Share with your attorney later if need be. If you are in the USA, most businesses, schools, clubs, etc. would rather spend a few bucks now than deal with a possible ADA (Americans with Disabilities Act) lawsuit later. There are other laws dealing with classroom problems that may help. See an attorney specializing in ADA cases. Most offer a free 30-minute consultation.

Do you chance have a sensory processing disorder or similar? I would think he'd have to accomodate if you have a diagnosed condition.
