Turning off Audio Notification / Confirmation?

I'm sure there's a way to turn off or change the audio tones that play during the confirmation of action, but I can't find it. Anyone know if / how this is possible? Thanks!

THis is a Windows feature.
Select the audio properties of windows (look in the Windows control panel for the loudspeaker symbol)
Select the tabfolder "Sounds".
Try the exclamation mark warning and unselect that sound.
This will disable the sound for this kind of Windows warning for all programs.
If you do not want to see the confirmation dialog box for actions in MP3tag then untick that option in Extras > Options > Messages.

it is not possible to switch off the sound for MP3tag only.

I don't want to turn it off for all programs, just this one. When I'm editing tags, I am usually listening to music from those files. I would rather listen to the music than have this notification sound rudely interrupt me. However, when I am in other programs, I do want to hear the sound when things happen. Many software provide this feature; surely, having a checkbox in Options saying "Mute notification sounds" isn't too hard?
