You need to wait a few seconds (5-ish) for the data to populate once you've selected a region on the map. Here's the link if you want to skip the article: https://maps.bts.dot.gov/arcgis/apps/webappviewer/index.html?id=a303ff5924c9474790464cc0e9d5c9fb https://maps.bts.dot.gov/arcgis/apps/webappviewer/index.html...

  Perhaps the map is getting hugged to death right now? I can't get any data to load beyond the base geo layer. EDIT: hmmm, seems to be a bug. I see in the console it's expecting JSON from this url: https://maps.bts.dot.gov/services/rest/services/Noise/CONUS_road_and_aviation_noise/MapServer https://maps.bts.dot.gov/services/rest/services/Noise/CONUS_...

    ...MapServer?f=json does have JSON! It's just even when it errors it returns a successful response with the error page that's not JSON.

A friend of mind built an app called SoundPrint (https://www.soundprint.co/ https://www.soundprint.co/), which helps people find venues based on their noise level. Similar idea.

There are similar maps available for Switzerland for railway noise (day/night), traffic noise (day/night), aircrafts etc. Here's the example for daytime traffic noise: https://s.geo.admin.ch/722d116dec https://s.geo.admin.ch/722d116dec

  In Zurich right now and just want to say: quietest big city i ever been to. Only clocks are ticking!
  - nshelly 10y ago
    Agreed, as most of the buildings have great insulation or double-pane windows. Though during the summer, just don't have an open window facing a major inclined street like Universitätstrasse with constant tram and vehicle noise, and high revs up the hills (this is a major problem in SF, except many buildings are thinner and less updated). In Switzerland, one issue is the older churches ringing their bells every 15 minutes 24/7. The Swiss Noise Council is trying to limit the bell-tolling to day-time hours. http://www.swissinfo.ch/eng/for-whom-toll-the-bells-_church-bells-charm-and-annoy-their-listeners/40807288 http://www.swissinfo.ch/eng/for-whom-toll-the-bells-_church-...
    - homakov 10y ago
      Oh, those in central part? I didn't know it was 24/7. Always hated namaz thing in muslim countries but seeing it in CH, WOW.
enraged_camel 10y ago
Maybe I ran into a bug, but this doesn't seem useful at the neighborhood level. The data simply does not have high enough fidelity. Even at the city level the gradients are too blurry to meaningfully extract neighborhood-level information.
- r00fus 10y ago
  It's pixelated and ugly at the road-level but it seems accurate at least for my neighborhood. Will definitely bookmark for when we buy. Road noise = less desirable.
- dawnerd 10y ago
  I had the same problem but after about a minute of waiting it loaded higher resolution data.
- adolph 10y ago
  It just extrapolates noise level from traffic surveys/estimates. It isn't like they have a microphone in your neighborhood.
tabeth 10y ago
If you really want to know this, go take a look at Google's traffic maps, which are decently accurate. Cross reference that with some city stats on the types of car available and noise levels for makes and models and there you go. Cars and trains probably make up most of the noise levels so it's probably a decent estimate. Sounds like a fun side project idea. - For city level data you could either go on Autotrade and look at cars being sold in a given city over a 10 year period and hope that's a decent approximation, or somehow get car registration data.
- solidr53 10y ago
  Adding flight data to it should be no problem as well. Then map it over period of time to see highs and lows :)
  - knz 10y ago
    "No problem"! You underestimate the volume of data (tens of thousands of points per flight) and time needed for temporal spatial analysis. I routinely run spatial analysis queries on a 400NM buffer around a large US airport and have spent many hours improving the efficiency of the queries due to the long run times on the largest RDS instances available. Running it for the entire national air space would be a significant project. Edit: I pulled one random day of data - using the data source with the least frequent reporting period (ATC Center - one point every 12s) there were ~ 600,000 data points for one day of operations that arrived or departed from our facility (overflights or GA to smaller airports are easily another 15%. This is also clipped at a 400NM radius). Annualized that would ~220 million data points. If you are looking at ground noise then you would probably want to merge in the approach radar data which is approximately one point every 3 seconds for a ~60NM radius. We often run multiple years at a time. It might not be "big data" by the standards of some on HN but it's significant for many GIS shops!

Its interesting how far across the city the noise pollution of an airport effects
- knz 10y ago
  That's because the contour extends far beyond what would be perceptible to a human in an urban area (it goes out to the 35 LEQ contour).
eisrep 10y ago
Neat idea. Although I think it's basing this mainly (only?) on road and air traffic data. It doesn't seem to include noise generated by the railways--at least where I looked.
- happy-go-lucky 10y ago
  "Road and Aviation Noise in the United States" is at the top. > future versions of the National Transportation Noise Map are envisioned to include additional transportation noise sources, such as rail and maritime. That's in About.
- mentat 10y ago
  Yes, the lack of railways significantly impacts accuracy on SF peninsula at least.
  - kosievdmerwe 10y ago
    Good ole Caltrain. Or more annoyingly the freight trains that run at 2am and are even more noisy.
- Arizhel 10y ago
  It's not supposed to, yet. But that is pretty important. My gf lives in an urban high-rise, and it's not noisy at all, except for the (above-ground at this point) subway that runs right next to the building.
amalag 10y ago
A little useful but you could just draw the same noise map using distance from airports and large roads. Is that how the noise map was generated anyway?
knz 10y ago
The map is a bit disingenuous for airports due to the metric used and the contours shown (out to the 35 LEQ contour?!). Federal Aviation Regulation Part 150 established Ldn/DNL as the cumulative noise exposure metric for use in airport noise analyses and is used to determine mitigation eligibility (usually around the 65 DNL contour). I suspect there are more than a few people at the FAA and airports around the country who are not impressed that the U.S. Bureau of Transportation Statistics published this map. Community relations are hard enough without maps that use the wrong metric and show contours beyond a reasonable value in an urban area.
- Anechoic 10y ago
  For those of you that don't speak "noise control": Leq is the Equivalent Noise Level, is the energy of sound averaged over a set time period (usually an hour, the BTS site is doing it over 24 hours). Ldn/DNL is the Day-Night Noise Level. It's basically the same as a 24-hr Leq with one difference - 10 dB is added to noise levels generated between 10:00pm and 7:00am to account for increased/sleep sensitivity at night. My guess is that the site uses Leq because highway noise data is generally calculated using peak hour Leq and it was easier to get airport Leq data than to calculate highway Ldn data.
  - knz 10y ago
    > My guess is that the site uses Leq because highway noise data is generally calculated using peak hour Leq and it was easier to get airport Leq data than to calculate highway Ldn data. Agreed. They should still know better than publishing something with contours out to 35 though! There is already a push by communities to mitigate aviation noise beyond the current level - 55 DNL is a number often thrown around and that often causes debate over ambient noise levels in an urban area etc. This map is going to cause headaches and confusion with the public.
    - mjevans 10y ago
      What I don't understand is why as a society we don't designate those areas non-residential to begin with. Beneath a flight path should be warehouse / industrial and possibly commercial.
lacampbell 10y ago
How you're affected by noise is not quite that simple, is it? As someone who must have been a guard dog in a previous life, I can sleep absolutely fine in the middle of a busy city or next to a busy road or near an airport. But it's the noise variations that gets me. IE in residential areas outside the city it's usually very quiet at night, except when it's suddenly not. In the cities its always pretty loud so there's little sudden change of noise.
- maxxxxx 10y ago
  I only notice when I visit my parents. It's super quiet there and I often sleep for 10 hours or more. I never sleep that much at home with air condition noise from the neighbors and cars driving by. Sometimes when there is a power outage you suddenly notice how quite it can get without all the background noise.
ebrewste 10y ago
It doesn't even account for all airports. I live near a Navy base and it doesn't show a thing, despite fighter jets making loops around the base. The nearby commercial airport is shown prominently, though.
- bnycum 10y ago
  I also live near a military base, and it's not accounted for either. B-52's aren't exactly quiet. Both the regional airport, and smaller airport are shown fine though.
- mohaine 10y ago
  If you look it is really a "National Transportation Noise Map" from the Bureau of Transportation Statistics. I'm pretty sure those fighter jets are not considered "transportation"
- dawnerd 10y ago
  I used to live near a Navy Base and their planes/helicopters would rattle the house every week. I think if they took that into account the whole city would be bright red...
- paulddraper 10y ago
  It definitely accounts for airports around me. There's a big N-S swath for SLC, and then a smaller X at PVU for the frequent flightpaths.
- dahart 10y ago
  And a few of the airports seem wrong. Not sure if it's a bug, but check out Klamath Falls, Oregon and Bangor, Maine. The noise contour of Klamath is visibly wider than the entire Bay Area, that seems unlikely.

Back in the day, I often went on long bike rides in the country on clear summer nights when the moon was full. I could see well enough once my eyes had dark-adapted, it was cooler, and there were fewer motor vehicles. And it was so quiet that I could hear interstates several miles away. So basically, I was mapping quiet places. Now there's an app for that. Edit: Now we can have crowd-sourced maps of quiet places.
Shivetya 10y ago
Well I am an area which shows no levels but there are areas within ten or so miles. It could all change if the county officials get their way and have Atlanta's second major airport in our county (Paulding). It would explain the recent boom in housing in formerly dead/bankrupted developments which came to life again. while some bemoan commutes and laud living in cities, noise is one of the greatest reasons to not live in one. For me the costs are worth it. i am curious how crime rates stack with noise levels, do higher levels simply have more crime because its a similar area or does the constant noise increase stress/fatigue to lead to more crime?
