I've noticed that when falling blocks fall it has no sound at all, despite it seeming like something that would make a lot of noise. I think it would be cool if they had a sound while falling. It seems like a fitting feature for this mod.

Hey! I've been messing around with this idea a bit and I've decided not to add this feature into sounds. I trialled using the elytra flying whooshing sound and various whoosh SFX's from Zapsplat, however it just doesn't seem to fit. Generally objects in real-life that are completely solid don't make any sound when falling either and the plain vanilla sound effects when a falling block hits the ground is in my opinion enough here.

I should have worded this better. I meant when they started falling. Like if you broke a floating clump of gravel in a cave it would make a collapsing sound when it started falling, and when it landed it would make another sound.
