ELI5: Why does some thunder crack through the sky doing a csshhhkrr sound and other ones produce a deep bass-boosted BOOOM?

Yes, we've had a thunderstorm recently and I love them, but can't get my head round this.

It largely depends on how close you are to it. The closer you are, the better the sound. It should resemble a loud crackle. But as you move away from the thunder, the sound wave starts to disperse and the sound gets less clear. So you ear a *boom* type of sound. Picture the sound wave as a bunch of people pushing each other in evry direction. After a while there's less of a reason to push people so the *fuzz* in that crowed gets less obvious, less clear.
