How does sound contribute to the effect of the poem "The Waste Land"?

Honestly, the best way to HEAR the poem is to listen to a recording of Eliot reading it. The link is in sources. The Wasteland is fecund with poetic device. I will turn to a page and give some examples, since to be exhaustive would take ages. As a rule, the poem does not rhyme, though there are countless examples. I will use "The Fire Sermon" to show how Eliot uses sound. There is an onomatopeia - "Twit twit twit/jug jug jug," there is a rhyme "Year to year...time to time I hear." This also uses a repeated word in two consecutive lines. An alliteration on this page "a taxi throbbing waiting/I tiresias." Just glance at any section and you can find countless examples.
