how can hack the sound files to remove the ping sound?

Humpink, on Sep 26 2011 - 10:05, said: Since the WoT devs didn't have enough foresight to include the "Attention to sector ..." ping sound into the ignore option, meaning that if I ignore a player I still hear (and see) the "Attention to sector ..." spam, I figure that there has to be some way to remove the ping sound from the sound files and get some peace and quiet that way. Anyone any idea on how to get this done?
