Is there a way to get DS to stop doing this? He makes such a high pitched sound/noise and it's starting to make my ears bleed. I tell him he can do it in his room but that only works so much. For example: he'll make the noise in the car (which is super distracting). I have tried putting on his headphones and/or covering my ears to tell him it's too loud and hurts my ears, but that has no effect.
I really need and want to break this habit. I can't take much more of the loud, high pitched sounds. Our dog also seems to be affected by the loudness.
