New mathematical method provides better way to analyze noise
Humans have 200 million light receptors in their eyes, 10 to 20 million receptors devoted to smell, but only 8,000 dedicated to sound. Yet despite this miniscule number, the auditory system is the fastest of the five senses. Researchers credit this discrepancy to a series of lightning-fast calculations in the brain that translate minimal input into maximal understanding. And whatever those calculations are, theyÃ¢â‚¬â„¢re far more precise than any sound-analysis program that exists today.
In a recent issue of the Proceedings of the National Academy of Sciences, Marcelo Magnasco, professor and head of the Mathematical Physics Laboratory at Rockefeller University, has published a paper that may prove to be a sound-analysis breakthrough, featuring a mathematical method or Ã¢â‚¬Å“algorithmÃ¢â‚¬Â thatÃ¢â‚¬â„¢s far more nuanced at transforming sound into a visual representation than current methods. Ã¢â‚¬Å“This outperforms everything in the market as a general method of sound analysis,Ã¢â‚¬Â Magnasco says. In fact, he notes, it may be the same type of method the brain actually uses. . . .
