This article by Dianne de Guzman,, reports that the San Francisco area’s Bay Area Rapid Transit system trains have been made quieter after repairs to track and wheels. More importantly, BART has ordered 775 new cars to be delivered in 2022, and these cars have specifically been designed to be quieter.

I have hyperacusis.  Sounds that don’t bother others are uncomfortable or even painful to me. I rode BART from the airport to downtown on a recent trip to San Francisco. It was certainly quieter than the subways in New York and London, but I still put on my noise-cancelling headphones (which were in my backpack for the flight up to SFO) because it was loud enough to be uncomfortable for me. I didn’t measure the sound pressure level, but I would estimate it to be 80-85 decibels, and that’s loud enough to cause hearing loss.

Subway noise is a problem in many cities, New York and London among them. But as New York City’s newest subway line and BART show, public rail transit can be made quieter. As The Quiet Coalition’s Arline Bronzaft, PhD, wrote: if there’s a will to make subways quieter, there’s certainly a way. This isn’t rocket science, simply bread-and-butter acoustic engineering.

And that’s perhaps the most important point. There seems to be a growing awareness that urban noise is a problem, and that it’s actually relatively easy and not all that expensive to make cities quieter.

Because if the subway sounds too loud, it IS too loud.
