Could it be standard practice for TDs to tell players, before the start of each round, to turn those blasted beepers on their chess clocks off?
Frankly, I do not know why chess clocks are sold with this feature to begin with; it’s annoying and useless.
Several times, during a tournament, I have had to get up and direct the TDs attention to someone’s clock that is beeping on every move. It’s like some folks seem to think they need to let everyone in the playing room know that a move has just been completed in their game.
The answer to trhis is simple, along with time controls and announcing when the games should start, TDs can also tell people to turn their blasted beeper functions OFF.
Otherwise, this should be treated like a ringing cell phone.
Many digital clocks have an auditory indicator that a start/stop button has been pressed, but I’ve never heard a beep so loud that everyone in the tournament room knows it. The beeps I have heard are no louder than the click of an analog clock being punched; most of the time those are louder than any beep. There may be a rapid succession of beeps/clicks during the opening phase of the game, but unless the time control is less than G/10, it usually quiets down after about ten to fifteen moves.

Maybe we ought to keep the cell phones on then, as long as their ring tones are low. 
Is it too much to ask that it be a regular practice to eliminate annoyances like this?
Why are these stupid features on chess clocks anyway?
Some models of the Chronos have an adjustable-pitch, adjustable-volume beep-on-every-move option, which can be EXTREMELY annoying. Most players don’t use this option, though, so in practice this problem is usually less pervasive than cell phones ringing.

Yes, the beeps are not louder, but…
The beeps are inherently more annoying (perhaps because they are unnatural or high pitched).
I wonder why Tournament Organizers (or TD’s) do not bother to mention the Chronos clock code that matches the tournament’s time control.
How long does it take to announce the five characters “DLC1A”?

Because there are many brands of clocks besides Chronos. And many different models of Chronos. And several different settings that will do the trick – all of which allow the beep-on-every-move option to be either on or off.

On the touch sensor Chronos clocks the beep can be somewhat useful since with those clocks you don’t hear an audible press of the button like you do on regular button model. I keep the beep off on my Chronos touch sensor, but there have been times I haven’t noticed my opponent has moved because I didn’t hear anything. (I was daydreaming. 
) The Chronos beep is fairly soft, but the beep on the newer Saitek clock is very loud. I can hear that beep from far away and it’s annoying. That clock doesn’t need a beep since when you press the button it can be heard. Same thing with the Fidelity clock. Too loud!
Right. I have a Chronos touch sensor too (am getting a Duel Timer, though) and I can see your point. However, with typical board placements in tournaments, where your neighbor’s every breath can be heard, it’s still annoying to have the feature on.
