Sometimes I get frightened by what I read on TechReview about emerging technologies, but this one somehow does not seem invasive (although the potential is there I suppose). Basically, an app hears (via a smartphone microphone) sounds in the carrier's environment and that triggers events.
In education, I can see a sound at the end of a video signally an app to begin a quiz on the material. I can see college campuses with the system set up to provide extra study resources as a reward for students attending lecture (or at least sending their phones to lecture).
OK, now that I think about it, the potential for abuse is pretty high!
I thought you might be interested in the following story on TechnologyReview.com:
"Startup Sends More than Music through Speakers"
Sonic Notify uses sound waves to let your smart phone pull up everything from coupons to music videos.
