When we think of pollutants, we’re inclined to list off things like plastic, coal, and carbon before we even get to noise. But noise pollution is a problem–so much so that LA has launched a soundproofing program, one that, controversially, has left out some poorer neighborhoods.

Hearing loss is one of the most common occupational hazards. A significant portion of US workers are affected by some form of hearing loss, and a smaller portion suffers from tinnitus (a consistent ringing in the ears).

Outside of the workplace, the average citizen is likely to encounter large amounts of noise from traffic. The OECD (Organization for Economic Co-Operation and Development) reports that traffic density is a huge factor in the levels of noise pollution country to country, with South Korea being one of the most polluted places in this regard.

Prolonged exposure to high levels of noise pollution contributes to higher levels of stress hormones, which in turn cause multiple health complications.

Soundproofing programs, quieter cars, and better workplace safety measures can help reduce the overall effects of noise pollution.
