Inside the science of negative sound effects, and what we can do about them.Mother Jones, writes about our increasingly noisy world and how this noisy soundscape is “contributing to stress-related diseases and early death, especially in and around cities.” The problem is that ‘[b]y evolutionary necessity, noise triggers a potent stress response.” Williams explains that “[o]ur nervous systems react to noises that are loud and abrupt…by instructing our bodies to boost the heart rate, breathe less deeply, and release fight-or-flight hormones.” While this response may have saved us from predators way back when, today they increase our stress hormones, which adversely affects our health. Williams adds that studies on children and noise exposure show that “children with chronic aircraft, road traffic or rail noise exposure at school have poorer reading ability, memory, and academic performance on national standardised tests.”
The article is very interesting and one of the better mainstream media pieces on noise and its effect on human health. Additionally, Williams touches on an important topic that gets very little attention. Namely, Williams discusses the uneven impact of noise on disadvantaged communities:
You can probably guess which communities face the greatest sonic barrage: the same ones stuck with the worst air, the shoddiest housing, and so on. Noise as a social justice issue is just beginning to gain traction.
