Need some PA System Technician for my last year assignment

Hi !

I'm a last year french student who's doing an assignment in order to graduate. I need some PA System techs to answer some questions in order for me to answer the question : What are the differences and the common points between tuning a PA System when it's indoor or when it's outdoor ?
If some of you could help me, I would like it a lot ! I link the forms I made with all the questions : https://docs.google.com/forms/d/e/1...Wxc886X6U0iCk8yZyNIKxEEQ/viewform?usp=sharing

If this doesn't belong here, I'm sorry and don't hesitate to tell me 🙂
Thanks a lot for your time !
