Sound made when unlocking 520

[dmusicant]

My Nokia Lumia 520 is running Windows Phone 8.1 and I have it configured to play a sound when unlocking or locking the phone. The sound I'm hearing is a tiny click, a slightly different tone for lock versus unlock. I want the sound to be more dramatic (in particular for unlocking). Can I change that sound, maybe pick from several? I'm not seeing anything poking around in settings' menu and submenus so far. Thanks for help.
