I'm going to report a tv noise complaint
Why are you reporting a sound complaint?
The noise is causing me to have a headache.
Tell whoever has the TV on to turn it down first. There is no reason to get someone else involved if it is not necessary. They may not know how loud they are being.
I'm going to report them anyways.
You can report them if you ask them to turn it down first and they don't. That way at least you are giving them some kind of heads up.
