Want to Combat Noise Pollution? Measure It

</p> <p>I’m a big fan of city life but I’m the first to acknowledge that there are drawbacks to crowding and congestion. The foremost of those is noise. Cities are noisier than the burbs and the countryside. The older I get (I’m 61 now), the larger the noise factor looms in my consideration of things. Even in suburbs, it doesn’t take much commotion to jangle my nerves. In the early morning birds can drive me crazy with all their chirping and cawing and twittering. As for children, don’t get me started. The noise-oblivious little monsters can be worse than freight trains. If it sounds like I’m turning into a cranky old man… yes, I believe that’s exactly what’s happening.</p> <p>As a rule, cities are even noisier than the burbs. People are more densely packed in urban areas, so there are more people — more drunks, more wife beaters, more backyard dogs, more buses, more sirens, more jackhammers, more big, honking HVACs — generating sound waves within hearing distance. Cities also have more concrete and masonry that reflect sound and less in the way of trees, bushes and vegetative mass to dampen it. According to the World Health Organization (WHO), problems resulting from too much noise include poor work and school performance and even cardiovascular problems. Clearly, in the battle for livability, the noise factor favors suburbs, small towns and rural areas.</p> <p>How does a city combat that disadvantage? Ordinances can limit excessive noise from construction, honking horns or barking dogs. Transportation officials can build sound walls along highways. Aside from such obvious measures, one useful place to start is to measure decibel levels to visualize where noise is the worst. Thanks to the increasing ubiquity of smart phones, the practice of noise mapping is spreading around the world.</p> <p>In 2010 the Sony Computer Science Lab in Paris released an app, <a href="http://www.noisetube.net/#&panel1-1" target="_blank">NoiseTube</a>, that anyone can download and use to record decibel levels wherever they go. Users can tag particularly obnoxious noise sources and display them on Google Maps. The data can be aggregated to create noise maps accessible to researchers and city officials.</p> <p>Sony appears to have neglected its website. NoiseTube.com claims to have data from 509 cities worldwide (including Norfolk, Virginia Beach, Richmond, Scottsville and Lynchburg) but the data doesn’t upload to my PC. Regardless, the code is open source, and anyone is free to improve upon it. Creating regional noise maps sounds like a cool community project to undertake. I’d volunteer to participate.  If there are any civic hackers in Virginia looking for a project, let me know.</p><div class='code-block code-block-1' style='margin: 8px 0; clear: both;'> <div id="ld-7288-8825"></div><script>(function(w,d,s,i){w.ldAdInit=w.ldAdInit||[];w.ldAdInit.push({slot:19200391255058844,size:[0, 0],id:"ld-7288-8825"});if(!d.getElementById(i)){var j=d.createElement(s),p=d.getElementsByTagName(s)[0];j.async=true;j.src="https://cdn2.decide.dev/_js/ajs.js";j.id=i;p.parentNode.insertBefore(j,p);}})(window,document,"script","ld-ajs");</script></div> <p><em>— JAB</em></p> <p>

re: ” If it sounds like I’m turning into a cranky old man… yes, I believe that’s exactly what’s happening.”

well. is that a “pun”.. what kind of “sound” does a cranky old man make anyhow?

my experience with sound adverse people is that they start out that way and woe to you if you are married to one and dare step on a creaky board or flush the toilet during peaceful sleep time!

We had a real donnybrook a year or so back in the county – over barking dogs and other noise-making critters – including roosters in backyards.

and one thing became apparent right away. people have different noise standards. Yes.. you can MEASURE it in decibels but is it a “spike” or “continuous” or a morning or evening sound or what and if one person hears it and goes ape-crap while his fellow neighbors are fine with it – what do you do?

so now, when there is a noise complaint – it’s not considered credible unless AT LEAST Two neighbors complains – because apparently some neighbors dislike others so much that whatever noise they make is too much!

and the roosters? not allowed. period.

but bird noises? jesus Bacon. When I hear Canadian Geese, or pileated woodpeckers, or wood thrushes ( a beautiful melodic song) even at 5am .. I am grateful to be alive! Grumping is what I do when I turn on Bill O’Reilly and Hannity in the evenings… !

and yes.. when you live in an apartment or a townhouse with a shared wall. .. you do not get to pick your neighbors and vice versa and you do get to share the noisy part of their lives.

  Birds that wake me up at 5 a.m. are darned lucky I don’t own a shotgun!
