Of course you could also take a less expensive and less passive approach when you encounter those loud talkers and just confront them about their annoyance, or pass them one of these specially designed notes for just such an occasion.

This cell phone Jammer claims to block GSM/CDMA/DCS/PHS/3G cell phone signals from a small, 6 ounce battery-powered device you can hide in your pocket and turn on when needed. It can be charged from a car charger adapter and runs up to 4 hours on a single charge, blocking others annoying cell phone calls on public transportation, restaurants or movie theaters. You can also use it to help you out of an unwanted conversation of your own and not have lie about losing your signal.
