Turning off just email notification sound Possible Duplicate:
  How can I turn off Notification Sounds and leave phone sounds on  




my dad just got a brand new Motorola XT603 running Android 2.3.5.  He would like to differ the notification sounds for emails/texts/voice mail but short of that, just turn off the sound for emails since he receives so many.  His email is NOT through gmail, but a work account.  Thanks in advance!
The easiest way to achieve this probably is:


get yourself an "empty" mp3 (i.e. one without any sound).
on your device's SD card, create a folder named media/audio/notifications (if it's not already there).
copy that "empty MP3" into this folder
Now select this file as notification sound for new mail


So when the new mail notification sound is being played, you won't hear it anymore :)
