Is there a logic behind how the numbers are displayed? Or was just randomly chosen by the creators?

So sounds themselves can hold a whole palette of meaning. Let's say we bound to the "r" in example the properties of rolling, transporting, roaring. It signals something which makes mechanical noise, something with an engine.
But we can go further in our abstraction and we can use it for other loud noises, thunder, or for the speakers of a hifi system. Or shouting, and purring noises, we might even want to use it to refer to a cat (with other sounds that express catiness). It can mean resonance (sound waves), but also used to things which (in abstract way) "resonates" well with us or the other way, they are unpleasant.
So we can make a building block out of the sounds which could be used in great many words like legos.
So we don't just look at a thing we want to create a word for, pick a letter from it's "name" (in whatever language) and glue it to the name of a similar thing we already done with.
