FYI: Is There a Scientific Way to Measure How Bad a Fart Smells?
Popular Science ^ | 9/1/2009 | Bjorn Carey

Posted on 09/11/2009 6:39:55 PM PDT by Saije

You’re in luck. For their senior project, two Cornell University computer-engineering whizzes recently built a machine that does just that. After learning in class how breathalyzers work, Robert Clain and Miguel Salas assembled a fart detector from a sensitive hydrogen sulfide monitor, a thermometer and a microphone and wrote the software that would rate the emission. A “slight perturbance in the air” near the detector sets it to work measuring the three pillars of fart quality: stench, temperature and sound. Temperature, Clain explains, is critical. The hotter a fart, the faster it spreads. “It beeps faster if it’s a high ranker, and a voice rates it on a scale of zero to nine,” he says. “If it ranks a nine, a fan comes on to blow it away. It even records the noise so you can play it back later.” After a few months of construction, they began field tests. “Well, the sample data wasn’t the entire school, but we definitely tested it,” Salas says.

The contraption could even have use outside of fraternity houses, Clain says, as a biosensor for harmful hydrogen-sulfide-producing bacteria in hospitals. Or dentists could use it to measure oral malodor. They’ve also received some interest from doctors with four-legged patients. “You can test the health of livestock through the quality of their farts,” Salas says. “Smell and sound can tell you a lot about their bowel movements.”

When I was a kid I knew another kid who could fart at will. He was a riot and the most popular kid in the neighborhood. Then one day, after one of his fartapaloozas he accidentally crapped his pants. We laughed at him mercilessly. He never did it again.

I think it was the late (very lamented) George Carlin who observed, “Did you ever notice how your own farts don’t smell that bad? (Farts) That was fairly decent!”

...assembled a fart detector from a sensitive hydrogen sulfide monitor...

Bah, detecting the toot is child's play, only a well trained human nose can whiff the subtle overtones that lets one detect a beer fart from an egg fart, a cheese fart from a broccoli fart, a peanut fart from a chili pepper fart and the multiple "nose" farts like the Domino's fart from a Taco Bell fart. Science can only go so far, it is the noses of highly trained men that are the ultimate fart experts.

three pillars of fart quality: stench, temperature and sound...

Totally ignores controllability, the keystone of historic farting.

I can see why you might think that but what I found interesting about the article wasn’t so much the tee hee aspect but that these college kids actually invented something that might be useful. They’re the whiz kids of the future. Today it’s a class project with a certain frat boy yuck yuck element but once they grow up a little they might just invent something truly amazing.

Now...if they want a rating system, they need to consider the KIND of fart they’re trying to rate.

For instance, a room-clearing SBD (Silent But Deadly) might garner a high rating. But is it better than, say, a fart that’s so loud and prolonged that it wakes up 3 men out of a sound sleep?

(Think such an animal doesn’t exist? Oh yes it does...because I did it. Lots of German beer + a good night’s sleep + horrid gas pains in the morning = the world’s worst alarm clock. Nearly ended my life, too. Not the fart itself, but I was almost pummeled to death by my 3 roommates.)
