The study focuses on three main things: road noise, air traffic noise, and industry noise. As part of that, it shows the link between annoyance at a noise and the chronic stress, anxiety, and health issues that come from that. For instance, Fig. 7 shows people are far more annoyed by road and aircraft noise than other types, including “neighborhood” noise, and Fig. 8 that shows the link between annoyance and rates of various issues. So it doesn’t seem to be saying that any noise leads to negative effects, but that specific types of noises act as a kind of environmental pollution.
