Randomized Skulk Sensor (Java)

This is another variant of the skulk sensor; it is crafted using skulk sensor and chorus fruit. I chose this particular crafting recipe because it then gives a more practical use to the chorus fruit, and it further encourages exploration to the End. The idea behind this is that depending on the number value of the sound it hears, it will output a random signal between 1 and that value. If it was an explosion, which I think has a value of 15, then a random signal between 1 and 15 would be generated. I got this idea partly from a MATH function in Java. There may already be a simple way to do this in-game, but I want a way to be achieved without the use of commands or an unnecessarily heavy redstone setup. Please share any thoughts you have on this, or if you have a better idea
