The damaging screams of sprawl

Noise pollution isn't just a thing you experience living next to an airport or interstate.

I have to be Captain Obvious and say long-term excessive noise sucks. Beyond the obvious issue of hearing loss, research has shown that prolonged exposure to high noise levels can lead to a range of problems, including:

1. Increased Annoyance: People get easily irritated and frustrated, impacting their quality of life.

2. Daytime Sleepiness: Disrupts sleep patterns, causing daytime sleepiness and fatigue.

3. Hypertension and Cardiovascular Disease: Studies have established a clear link between chronic noise exposure and elevated blood pressure.

4. Cognitive Impairment: Affects our ability to concentrate, learn, and solve problems effectively. It’s even more traumatic for children because their brains are still forming.

Hospitals are one frightening example of adverse effects of excessive noise:

1. Reduced Staff Performance: Noise exposure in hospitals impairs staff concentration and communication, making it harder for healthcare professionals to perform their jobs effectively. A mistake or oversight by hospital staff can have disastrous consequences.

2. Worse Patient Outcomes: Patients subjected to high levels of noise during their hospital stays experience increased stress and discomfort, which can hinder the healing process and, in some cases, lead to worse clinical outcomes.

Sprawl development is white noise

Sprawl, characterized by the regulated expansion of land development, is a significant contributor to the prevalence of noise pollution. The 6- and 8-lane arterials feel inevitable because how else would you connect all the various land use zones: housing, commercial, working, shopping, recreational, and so on. 

Land use policy plays a pivotal role in perpetuating sprawl and, consequently, excessive noise pollution. Many conventional zoning practices aren’t necessary evils to create a civilized society, but unnecessary evils. Restrictive land use rules exacerbate the noise problem.

Sprawl, and its noise generation, is a problem that can be addressed at the local level where community design and land use policies are decided. 

Legalize Mixed-Use Neighborhoods

Encourage local leaders to revise zoning regulations to permit mixed-use neighborhoods, where essential services are within easy reach. This eliminates the need for massive, noisy arterials. Automobiles are still allowed, they just aren’t the only viable option to get around.

Enable Active Transportation

Advocate for infrastructure that supports walking and cycling, reducing the reliance on noisy vehicular traffic. What’s the point of posters celebrating “bike to work day” if the infrastructure feels like hell. Look for ways to develop a network of routes for walking, bicycling, skateboarding, etc.

Talk to People

Engage with your local leaders and policymakers to raise awareness about the adverse effects of noise pollution and the benefits of quieter, more walkable communities. There are of course countless reasons to support good urbanism. But if the noise issue resonates with you, squawk about it.

Long-term excessive noise is more than an irritant. It's a silent menace that affects our physical and mental health, cognitive abilities, and even the quality of healthcare in our communities. There’s a ton of scholarly work on this topic. Here are a few places to start.
