The protagonist expresses a profound sense of depression stemming from a personal silence rather than an absence of sound. Although the external world is filled with noise from cars, people, and the river, she feels disconnected and unable to perceive any of it, as if she is trapped in her own emotional void. This illustrates her internal struggles, highlighting how personal turmoil can drown out the vibrancy of life around her.

The imagery of the city appearing as a flat, unengaging poster emphasizes her feelings of alienation. Despite the bustling life outside her window, it brings her no joy or connection. This reflects the overarching themes of isolation and the search for meaning in "The Bell Jar," encapsulating the contrast between the lively world and her own muted existence.
