Do My Feet Stink?
"Scientists have discovered a new smell, but you may have to go to a
laboratory to experience it yourself. The smell is dubbed 'olfactory
white,' because it is the nasal equivalent of white noise, researchers report in the journal Proceedings of the National Academy of Sciences.
Just as white noise is a mixture of many different sound frequencies
and white light is a mixture of many different wavelengths, olfactory
white is a mixture of many different smells. In a series of experiments,
they exposed participants to dozens of equally mixed smells, and what
they discovered is that our brains treat smells as a single unit, not as
a mixture of compounds to break down, analyze and put back together
again."
