How roadside noise barriers are designed to absorb sound and evade attention

The freeway sound wall may be as overlooked as it is ubiquitous. Lining interstates and highways and freeways across the United States, these concrete and cinderblock structures are a blur in the peripheral vision of our automotive world.

This is partially by design: sound walls serve the utilitarian role of blocking and containing the tremendous noise generated by high speed transportation, and they’re built to do their job without distracting the people driving past in thousand-pound vehicles at more than 100 feet per second.
