Coarse crackles are discontinuous, brief, popping lung sounds. Compared to fine crackles they are louder, lower in pitch and last longer. They have also been described as a bubbling sound. You can simulate this sound by rolling strands of hair between your fingers near your ear.

What are the subtle differences between these phrases? from my understanding, crackles is replacement word for rales. i've also heard of ronchi being thrown around. and then there's coarse breath sounds. I've used crackles for fine crackling sound like u'd get particularly at lung bases.
