"murmuring of an unknown tongue made a bedlam within which i was securely tied" explain?

The multitude of murmuring voices in an unknown tongue creates a background of white noise where even the thoughts in one's mind gets drowned and that can be comforting. As the writer describes that the variety of sounds such as the bell for breakfast, loud metallic voice crashing through the belfry and the annoying clatter of shoes stripped any serenity from the scene. The constant clash of harsh noises and the undercurrent of many voices speaking in several languages created a bedlam, a situation of cacophony in which she felt securely tied. It freed her from her own grief and struggles because there was no silence or peace in which to contemplate by herself, she felt swept away by the wave of noises.
