TOO MUCH RACKET - NOISE POLLUTION IN THE NEIGHBORHOOD

Noise in the city - a major impact on livability

​by Tarah Hodgkinson

5:15am – SLAM! CRASH! BANG! That is how I wake up every Tuesday, Thursday and Saturday morning. Three days a week, when the garbage and recycling truck comes to empty the bins below my second-floor window. It’s been three times a week for 5 months now. They start at the ungodly hour of 5:15am. Always waking me up.

The first time I heard it I nearly jumped through the wall. When I first moved into one of the units of the six-story apartment, I was told that the truck came twice a week.

I know I sound like I’m complaining. You might suggest I go back to sleep after they are done (not possible), or that I close my window (I do) or I turn on the AC and blast a fan and wear earplugs (check, check, check). You might say “calm down, you chose to live in the city” (try using public transit outside of a city).

But noise pollution (excessive noise caused by machines, transport and other humans) has a harmful impact on humans and animals. Numerous studies have examined the effect of increased noise levels on health. Noise pollution has been found to affect the nervous and endocrine systems and can cause numerous health issues from anxiety and heart disease.

Most importantly, it disrupts sleep, which can be a catalyst for all of these health issues, as well as low birth weights for pregnant women. Additionally, sleep disruption caused by noise pollution can also reduce focus and harm productivity.


NOISE AND CPTED

As Mateja and Greg described in their recent blog introducing 3rd Generation CPTED, there is more to neighborhood livability than fear and crime. Noise pollution and its impact on public health is part of 3rd Generation CPTED because of its critical role in creating successful, peaceful neighborhoods.

Busy streets along with noise capturing architecture can make noise pollution worse

​While crime and noise have very different consequences, both fear of crime and noise pollution impact neighborhood livability. If people do not feel comfortable in public areas due to noise, they will not spend time there. It’s difficult to get legitimate “eyes on the street” (1st Generation CPTED calls it natural surveillance) when residents are hostile towards their streets.

Fortunately, communities all over the world are starting to pay attention to noise pollution. New technologies are helping to better discern the impacts of noise pollution, and laws and regulations already in place are beginning to expand.  In fact, organizations like Noise Free, have made it their mission to reduce noise pollution as part of a larger public health mandate.


SOLUTIONS?

However, many suggestions for responding to noise pollution are individually focused on encouraging the consumer to buy expensive noise-cancelling headphones, rearranging their furniture in their house or purchase other muffling agents.

Even more extreme, some suggest that people just move. But moving to a quieter neighborhood is not an option for most people, in particular, because noise pollution tends to be worse in poorer neighborhoods.

Not surprisingly, those poor neighborhoods are often where crime and fear flourish and where we end up working to introduce SafeGrowth.

Noise attenuation walls - the typical response

​There have to be better local solutions to reduce these risks and protect those most affected.  Planners and developers already use highway barriers to reduce loud traffic, but this is not enough. For example, one solution might be educating policymakers on how to create local noise mitigation legislation, especially the sleep-interrupting version. It might be possible to better notify (and enforce) noise violators, improve tree coverage that can block noise, or create “no horn zones”.

Creating safe and livable neighborhoods isn’t just about reducing crime, its also about ensuring that city designers and decision-makers, and residents themselves, treat all neighborhoods fairly and ensure all forms of health and well-being are part of the 21st Century neighborhood.
