Start with a flute playing as softly as a human can hear it,that's pp. An orchestra with everybody playing as loud as they can play is ff.
Starting with pp,each doubling of volume(amplitude) is represented by a dynamic marking.(pp,p,mp,mf,f,ff). pp is 50 decibels,p is 60 db,etc untill you get to ff as 100db.(Many rock bands go to 110.)
Here is something you can do someday when you have time,if you haven't done so already: Get a score and play something that is marked mf and set your volume to a reading of 80db. Then you can check the dynamic range of your speakers. Wait untill you get ff and pp passages and take readings. If a ff is 100,and a pp is 50,their dynamic range is correct.
