Just become deaf it will solve your problem
double piece sound

When playing or watching live chess in a browser, other than by turning the sound off, how do I change the annoying double sound (tap, tap) when a move is made to a single sound (tap).
If you are playing on browser, here is the problem. You have another tab open, and since games sync, the sounds double up. So close the tab and sound is gone. Bro how did this go unanswered for 11 years??

If you think you have one tab open, the other tab is likely in an other window, and your setting choice can make it open another window, so you may not see the tab creating the noise.
If you're into double piece sound systems, you might really enjoy exploring more about old-school audio setups that bring depth and character to music.
