Like everyone has been saying, it varies.  I don't doubt that the
beans' moisture content matters, but I also know that different beans
that are sitting right next to each other in cloth bags (for half a
year!) in a pretty stable indoor environment can nonetheless have quite
different sound levels.

One of the most useful tricks I've learned about roasting with the
Nesco is to take advantage of something it makes visible that few if
any others do: the overall volume of the bean mass.  The notes in the
forum posting are a bit sketchy, the image is blurry, and it's all a
bit of an early, sloppy take, but apparently I haven't updated this:
