Day 158: Tinnitus Test
One of the few evil tricks I do….
I tell the kids I’m going to administer a hearing test. If they can still hear the tuning fork after I’ve stopped it vibrating by touching it with my hand, then they have tinnitus and should stop listening to loud music in their headphones before they do any further damage.
Of course, the ringing they hear isn’t tinnitus, but the sympathetic resonance of the other tuning fork nearby. They sure are relieved when I finally let them in on the joke.
