We built out a quick visualization of the noise data we've been collecting in the city. Again, the link is here: http://tendernoise.movity.com.

Our goal for this noise project is to show the affect of noise (from muni, cable cars, bars, people) on the quality of life. We're going to collect and scale the data to other neighborhoods shortly.

It's v.1, so let us know what you think.

I used to live in the TL, your graph suggests there are no police sirens around 12am - 4am, I find that hard to believe. =)

Maybe you could add sound samples? Would make the whole experience a bit more personal...

Interesting - is "average" noise level defined as a 5-minute Leq?

I'm curious to see how you expand this to other metro areas. Arup has deep pockets but I suspect not deep enough to cover even most metro areas in the USA, and (unlike the EU) we Americans aren't really big on noise-mapping our cities.

What do the lengths of the coloured bars in the bottom panel represent?

Edit: Oh and I forgot to say this is awesome. How did you make this?

The range between the highest and lowest db reading at that given moment. The measurements were taking by us, analyzed by Arup (Arup.com), and visualized by Sha Hwang. He literally built it in 2 days and one of the few folks who specialize in data visualization.

Very cool. Are you considering releasing the data? It would be interesting to see the same data explored and visualised in other ways.

That's pretty nice. Looking forward to seeing more from this.
