The New Noise is Obnoxious

There's this new sound effect, it's like a very short buzzer. It sounds like there is a housefly in my ear every time it sounds. And it sounds frequently; if you are thinking of moving a piece, before your opponent has moved and you have already clicked it (I usually play blitz and bullet) but you haven't moved it yet, then when it is your turn if you don't un-click it before selecting a different piece, this little buzzer goes off. It didn't used to be there, so it must be new. But it's terrible. 

I like to hear the sound of the pieces themselves being moved, so I don't want to just turn off all the audio. It would be nice if there was an option to disable just this sound.
