NoiseTube: mobile phone monitoring of noise pollution

They even tested it in Brussels:

Nice concept. I’m wondering how they deal with “fake” results as in: “driving around in your car with loud music”.

  1. How to exclude “odd” findings? Basic statistics: ignore results that overshoot the average values at that spot by far.

    Only problem is that by doing so things can go wrong though: Ever since the 70’s scientists ignored the ozone layer problem as those measurements were “way above average and most likely erroneous”. It wasn’t until a guy actually noticed that the “odd” results always occurred at the very same spot (viz. the north pole) they made extra measurements confirming those odd results as actually being real and genuine, turning it into an acute problem.

  2. I don’t usually comment on blogs but had to on yours. You have a very distinctive writing style. A lot of people don’t have that touch, they just drone on and on in the most boring way. But not you – thanks! Don’t have time to read everything here at the moment, I found your site while looking for something else on Yahoo. But I’ve bookmarked your homepage and will visit it regularly to read your latest postings. I love reading sites about geocaching. It’s such an exciting topic. Thanks again for a very informative site! Visit my site if you’d like to read more.
