I define buzz as more of an HF noise, of no particular frequency. Hum is, in my book, AC line frequency (50/60hz depending what part of the world you are plugged in) and its harmonics: 100/120hz, 150/180hz, 200/240hz, 250/300hz etc. The two sounds tell a very different story as do the different frequencies of hum. best, ike I use the same parameters to distinguish between the two, but I should have clarified with the OP because, as you said, "buzz" and "hum" usually point to different causes.
