[FFmpeg-user] What exactly is an "amplitude ratio"?

I'm using the silencedetect filter for a project, and I've been using an 
amplitude ratio for the threshold (i.e., n=), but I'm not sure what this 
actually refers to. My guess is that it's a percentage of the peak 
amplitude in the file (e.g., 0.01 is 1% of the highest amplitude), but 
there's nothing in the documentation that I can find that defines this 
term, and I've never seen it anywhere else. Is my guess correct or does 
amplitude ratio refer to something else?
