A city of over 8 million people, there is no denying that Hanoi is noisy. For those of us not born here, it may take some adjustment, but in time we relax and pay little heed to the neighbors’ barking dog, the chorus of child’s play, or the constant hum of motorbike madness. We learn to share audio spheres, holding tight our sanity while swimming in soundscapes of communal living. And though certainly an element less celebrated than the visual landscape, the sonic experience greatly affects our understanding of, our relationship with, and our navigation of the city, forming memories and influencing daily actions.
