I have grown up in the NYC area my whole life, but this was probably a nationwide PSA that I have only seen once and never again. Saw it before I turned 10.
I believe it was for some organization or institute: a featureless, unmoving mannequin head and neck in a dark room with faint lighting. In slow shots that faded from one scenario to the other there was the sound of some large noise (probably construction work); then a pair of headphones on the mannequin with audible music; then some other loud noise (probably trains in the subway).
The part that creeped me out was the final shot of the mannequin head, each ear having a glowing red spot and the shrill, deafening sound of what seems to be tinnitus from the exposure to all of those intense decibels. The high-pitched ringing seemed to go on forever but probably lasted for a few seconds at most. I do not recall if there was a narrator at any point in this, but I do believe this was from the late 80s.
I haven't a clue where to begin my search! I know the Kindertrauma family are super spies and I just know it can be figured out. Even without an answer, I think you guys are great besides!
