Brymen meters "beep" on diode check?

A continuous tone for a short and a lone beep for a good PN junction:
Fluke 289 287 87V 233 179 177 175 117 116 115 77IV 73III 83 110(Old USA model, presumably 111 and 112 also) 12(Old, presumably the 11 as well) 27/FM
Keysight U1233A U1232A U1273AX U1273A U1272A U1271 U1281 U1282 U1241B U1242B
A continuous tone for a short only:
UNI-T UT61E
UNI-T UT71 UT181A (adjustable mV threshold)
Gossen MetraHit 29S 28S 26S/M (adjustable mV threshold)
Hioki DT4282 DT4281 DT4252 DT4253 DT4256 (adjustable mV threshold and LCD red light)
Voltcraft VC890 VC880 (adjustable mV threshold)
Appa 305 (adjustable mV threshold)
Protek 608 (adjustable mV threshold)

added to Fluke.

Yes I'll second the Fluke 12 doing the "beep" so 10 and 11 will as they have the same board in them
I found a Fleabay seller in China selling what is supposed to the correct part number of the Fluke 12 LCD display so I've decided to gamble US $35 to see if it's legit and I can resurrect my broken one (sorry can't find a fingers crossed smiley)

I am confused, what are the benefits of beeping on ~<0.1V vs. beeping on ~<15 ohm?

What do you normally use to check semiconductors, diode or continuity?
Do you ever work in the field where you need to focus on where your probes are placed and not the screen and you might find it useful, same for the short beep on a good junction.

I see, I got the impression you used it for continuity testing. If you need to repeatedly verify the forward voltage range of a semiconductor without being able to see the DMM screen, an audible buzzer would be useful.
