Single-Sided Hearing Deaf Awareness Button

I have been deaf in one ear since I was nine years old. I can't remember what stereo hearing sounds like; and what I've heard sounds a little fanciful to me. One of the more annoying things about those with full hearing is when they forget about my deafness. My occasional lapses in speaking volume are met with an urgent, 'Keep your voice down!'. Often it's accompanied by hand signals or gestures, which are more usually used to command a dog. This is a badge for those who want to flip things on their heads. Instead of feeling mortified or infuriated that you're being shushed, point out that if everyone was partially deaf, then you wouldn't be speaking too loudly at all. At the very least, it's a humourous way to ramp up their deaf awareness and maybe elicit a friendlier, more patient and mature way of alerting you to your apparent loudness.
