This thread was done before.....word for word....was it here? IP? I have read this before.
It does not matter what we call ourselves. We are normally referred to as the "TV guys" or "Sound guys". People who somewhat get it will use "Audio/Video technician" but I have never, not once, heard anyone outside of other CIs refer to us as such. Even if they did, whomever they were talking to would not have a clue what they were talking about. Unless it was you.
Just get a PHD and call yourself a Dr.
