Deaf Trait build help

Basically title. Im already HoH and have struggled with hearing perception, and because i like to call with friends while I play and just want to focus on my friends voices, I just find deaf traits as a free +12 points

Do you guys have any recommendations to help with playing deaf? Are any of the vision traits worth it? Is taking thin skinned bad due to being more likely to be snuck up on? Lmk im a very new player and most guides dont even really talk about deaf in depth
