Noise cameras to the rescue!

But, sadly, not in the U.S.  Motorbike Writer writes that Australia is monitoring the British development and deployment of a new noise camera that is intended to be used to “crack down on illegal vehicles.”  According to a UK.gov newstory, the new camera “will aim to detect illegal, excessively noisy vehicles, helping create quieter streets.”

Mercifully, this technology isn’t anticipated yesars from now. Rather, trials of the noise cameras will take place in “the coming months.”

The goal, of course, is to measure the sound level of passing cars, determine which are violating noise limitations, and, perhaps, deploy “automated number plate recognition to help enforce the law.”

No doubt there are those who will complain about the technology, but if it works it could help to address a common problem that police, to date, simply cannot or will not address. Importantly, the technology isn’t being deployed to harass motorcyclists and others who seemingly love loud vehicle noise.  The UK government makes it quite clear that it is testing this equipment to clamp down on noise pollution, which, notes Transport Secretary Chris Grayling, “makes the lives of people in communities across Britain an absolute misery and has very serious health impacts.”

We will be following this program and will keep you informed as to its progress.

Is Your Noisy Neighborhood Slowly Killing You?

Inside the science of negative sound effects, and what we can do about them.Mother Jones, writes about our increasingly noisy world and how this noisy soundscape is “contributing to stress-related diseases and early death, especially in and around cities.”  The problem is that ‘[b]y evolutionary necessity, noise triggers a potent stress response.”  Williams explains that “[o]ur nervous systems react to noises that are loud and abrupt…by instructing our bodies to boost the heart rate, breathe less deeply, and release fight-or-flight hormones.”  While this response may have saved us from predators way back when, today they increase our stress hormones, which adversely affects our health.  Williams adds that studies on children and noise exposure show that “children with chronic aircraft, road traffic or rail noise exposure at school have poorer reading ability, memory, and academic performance on national standardised tests.”

The article is very interesting and one of the better mainstream media pieces on noise and its effect on human health.  Additionally, Williams touches on an important topic that gets very little attention.  Namely, Williams discusses the uneven impact of noise on disadvantaged communities:

You can probably guess which communities face the greatest sonic barrage: the same ones stuck with the worst air, the shoddiest housing, and so on. Noise as a social justice issue is just beginning to gain traction.
