Snore-Canceling Earplugs

As most of you Braniacs already know, noise-canceling headphones work by "listening" to ambient noise and generating waveforms that inversely match the noise.

Flash forward to the present. (Okay, this has nothing to do with time travel; I've just always wanted to write "Flash forward to the present" here.) Many people with incurably snoring partners avoid earplugs because they worry they won't hear important noises—smoke alarms, kids calling, burglars breaking in, emergency phonecalls, ETs landing in the backyard, etc.

Snore-Canceling Earplugs are miniaturized noise-canceling devices optimized to cancel the types of sound patterns produced by undirected vibrating human respiratory structures. These patterns have specific, identifiable characteristics (because, prior to developing the actual algorithms, I'm saying they do).

For maximum comfort whilst sleeping, SCEs are custom- molded to each user's ear canals, like the custom protective earplugs worn by performing artists who can't use visible sound-blocking devices.

Now watch someone patent, manufacture and sell this and make a zillion bucks. Don't you hate it when that happens?
