I found it interesting when I was reading the beginning of the chapter. The way that our vocal muscles were stimulated as we read sounded very familiar to me. It makes a lot of sense to associate the psychology behind a word can make all the difference in the way something is conveyed.
In my own writing, I find it annoying, unproper, or even too easy to do alliterations and most uncommon onomatopoeias. Instead, I exercise this principle with words that have more conventional use like clink, click, clatter, chink, shatter, and rumble.
