A connection between noise pollution and cardiovascular disease has been observed in numerous studies over the years, the authors of the new review said. High decibel levels from road traffic and airplanes, for example, has been linked to high blood pressure, coronary artery disease, stroke and heart failure — even after controlling for other factors like air pollution and socioeconomic status.

But despite this growing body of evidence, not much is known about how, exactly, noise pollution might contribute to heart problems. In an attempt to shed some light on that question, researchers from Johannes Gutenberg University in Germany compiled and analyzed findings from dozens of previous studies on noise and various health outcomes.
