Hi. I am Alexis Dinno, a professor at Portland State University’s School of Community Health. Today I present ‘A pilot study of riders’ noise exposure on Bay Area Rapid Transit trains’ which distills and reflects on a paper written by myself, Cynthia Powell and Margaret Mary King currently in submission to the Journal of Urban Health. Bay Area Rapid Transit, or BART—logo shown here •—is a regional public rapid commute train system serving the northern portion of the San Francisco Peninsula, the East Bay, and portions of Contra Costa County. An average of 360,000 rides are taken on the system each weekday • on trains much like this one shown leaving Lafayette station in Contra Costa County. Despite occasional hiccups, and an early fatal tragedy in the system’s Transbay Tube, BART enjoys high customer satisfaction in most areas. However, there is a widely held perception that BART is too loud. How loud is “too loud?” In a sample of two people named ‘John’ writing in local newspapers, we find •: “After enduring another week of the screeching and howling while traversing BART's Transbay Tube, I feel compelled to inquire as to when BART plans on rectifying this,” and the second wrote “With regularity, readers contact ChronicleWatch about tunnel noise in BART—about how trains in the under-the-bay tube make excessive sounds as they speed to and from San Francisco, and how BART trains in other system tunnels make similar ear-splitting sounds.” My interest in noise on BART trains arose through my own personal experiences as a frequent rider. This is a map of the BART system •. I first rode BART when I was 6 or 7 years old, from the Rockridge station here in Oakland under the trans-bay tube to San Francisco’s downtown. (Incidentally, as the train headed down under the ground on that first ride, I was devastated that the tunnel walls were not made of glass: how else were we supposed to see all the fish under the Bay? I still feel the pangs of disappointment…) Flashing forward several decades to my 30s, I lived here in San Francisco, played here in Berkeley, and for a year taught part-time here in Hayward. Over the ‘Oughties’ I felt that BART was getting louder. Especially after a scheduling change started running trains a little faster about seven years ago. What was my experience of “louder?” Well… I took to always wearing good ear plugs my final years there. In fact, I witnessed child and adult passengers covering their ears with their fingers while riding BART, wearing ear protection such as plugs or audio muffles, and pairs of individuals leaning close together and literally shouting at high volume in order to carry on conversation. Friends who were not accustomed to regularly riding BART would complain of headaches on the rare occasions of their rides.
