Why Are Acoustic Walls So Important?

Highways may be modern miracles that can help people buzz around the country in a heartbeat, but they can also be a nuisance to anyone that lives around them thanks to the fearsome amount of noise they tend to produce. As a result, the installation of acoustic walls along stretches of highways that run past homes has become increasingly common, but that doesn't answer the fundamental question: why does the noise need to be reduced?

The Simplest Answer Still Applies
Before we consider the direct health implications of living next to such a noisy site, we'll quickly talk about the most basic answer: highways are loud, and nobody wants that. Try sitting next to a busy motorway and having a conversation, reading a book, or even catching some sleep. It's going to be much harder than it would in a quiet suburb, if not be outright impossible.

Solving A Problem We'd Made For Ourselves
Never before in history have humans had to erect barriers with the sole intention of blocking out noises they'd rather not hear. Sure, large castle walls likely had the same effect anyway, whether the nobility within were trying to ignore the creatures of the night or the cries of an angry mob. Either way, dedicated acoustic walls weren't created until 1968, in response to a study done a decade earlier by the University of California, Los Angeles. They were interested in dampening the sound of the Arroyo Seco Highway after it caused issues for the Hollywood Bowl theatre, though that was not the first highway to receive such a barrier – that honour goes to the Interstate 680 of Milpitas, California.

Protecting The Health Of The Community
While these highways might have started by interfering with public gatherings, they'd quickly start to snake along houses and residential blocks, posing a significant health hazard. These hazards came in the form of psychological complications, including an increased sense of isolation, depression, anxiety, and a difficulty to concentrate, but large amounts of noise can also be linked to higher blood pressure, insomnia, and fatigue. Clearly, this couldn't be allowed to happen forever.

Are Acoustic Walls The Final Solution?
While acoustic walls are able to dramatically improve the situation, they are a solution created after the fact. Ideally, highways should be designed in such a way as to reduce the effects of noise pollution on the surrounding population, but if they are put in a place that may pose a threat to a nearby community, than an acoustic wall is definitely a solution to consider.
