Thanks, I am happy to hear that sound therapy exist, however from the links you sent they seem to be mostly focused on improving cognition and hearing (as opposed to tolerating sounds).

Since in my state I am bad at reading and listening if you have further details on which method could help noise sensitivity please let me know.

To clarify, my sound sensitivity means that not only it bothers in the moment, it creates nausea that can last for days and increases sound sensitivity even further.

Link below suggest pink noise therapy.
