Sometimes I have to check my sound settings...
If I am ever too loud, please never hesitate to tell me.  I'd rather have the option to try and fix it before I am squelched by guys I am trying to work a fight with.  Often times, comms are life.   
And I die a lot (not because of comms either...   lol)!!!
I do try to test my mic about once a month but I do know sometimes the sound settings readjust from time to time so if I am blasting your eardrums, please let me know and I will fix ASAP.
