"There haven't been any proper scientific tests on brown noise," says Dr Geoff Leventhall, an academic turned noise vibrations consultant who is so invested in low frequency sounds that he's conducted several of his experiments on himself."Some kid with a subwoofer might play it up high, but that's just people messing around," he says. "There have been tests on the effect of low frequency noise on people, and I've also done some looking at the effect on task performance and productivity, but the effects aren't very great."He adds: "Scientifically there's something called white noise. There's also a pink noise and some people talk about a red noise, too. Beyond that, there's nothing that's really been accepted."So where do the myths about the brown noise come from? The internet has helped rumours spread faster than ever before, and satirical articles are regularly shared as fact on Facebook, but Leventhall believes the idea of the brown noise first originated from a spoof article in New Scientist from over 40 years ago.
