‘White Noise’ For Your Nose Cancels Out Nasty Odors

Scientists have high hopes for “white noise” for the nose.

It turns out that two researchers have found the mathematical formula to create an olfactory equivalent of “white noise,” which they say could be used to cancel out any pungent odors you may want to get rid of.

“This is different than traditional approaches to odor cancellation,” Dr. Lav R. Varshney, one of the researchers, who is an assistant professor in engineering at the University of Illinois at Urbana-Champaign, told The Huffington Post in an email. “Instead we take advantage of the perceptual properties of human olfaction to ensure what is perceived is this white smell.”

How does this work exactly?

Lav and his brother Dr. Kush Varshney, a researcher at the IBM Thomas J. Watson Research Center in New York, found that the chemical compounds in any smell you’re able to detect have an opposing set of odor compounds — such that when the two sets are mixed together, they cancel each other out.

The Varshneys put together a database of scents, matching odor compounds with ratings of various smell properties. Then they built a model that uses the database to take a scent you want to eliminate, and find —> Read More Here
