Like many students, I took 7 trains to and from LaGuardia Community College. Every day I get off the train at the 33rd Street station and walk westward through Van Dam Street for about three blocks until the school’s main entrance on Thomson Avenue. After the class, I returned to the station and took 7 trains home. As I walked between the station and the school, I could hear the train’s noise on the elevated track every few minutes. In the second episode of “The Way of Hearing,” the author talked about the massive increase in noise caused by cars, elevated trains, and buildings in the cities of the 20th century. Seven trains are a vivid example. At first, I thought that the sound was deafening (the train was exceptionally comfortable to hear in the library on the second floor), and tried to block it by wearing headphones, and tried to be with me, as the author said in The Way of Hearing World isolated. But over time, I realized that the train’s sound is actually part of the urban structure, and by hearing the hum of the train, you can even feel the city’s rhythm. For example, if the train passes quickly, I know it is an express train, which hurries to and from Manhattan. If the train passes slowly, I know this is a local train, and I will stop at 33rd Street. If I am walking back to the station and hear the train passing by, I know I have about 5 minutes or so until the next train arrives. Therefore, instead of turning off my hearing of surrounding sounds, I now learned to embrace the 7 train passing overhead sound. As the train passes by, rumbling and screaming on the tracks, they take people to meaningful work and school activities. Therefore, the train truly represents the lifeblood of the city.
