Nah. That’s a dull “hum” that is basically constant. Since it is constant it’s quite easy to tune out and forget it’s there. It’s the engines that break through and become distinct.

That's not what the research in the article says. The research is looking into the constant noise.

Clearly. And constant noise is not a problem. It’s inconsistent noise that is the big problem and what people notice. The article provides only correlation and no causation. It’s just as likely if not more that the exhaust and other air pollution from the cars is the problem.

I haven't read the actual research paper, but they claim to have controlled for air pollution and established causation.

It’s still just correlation. Showing causation requires a far more precise study than just looking at where they live and whether they developed hypertension or not.
