Please add an option to disable ambient sounds in LoL.

Currently the only way to disable ambient sounds (background noises such as the wind blowing, etc.) is to disable sound effects entirely. Sound effects are critical when playing LoL as they let you know what abilities are being used and it helps keep track of alerts being cast on the map (pings).

As a player I, and many other summoners, prefer to play my own music while I play the game, however the ambient sounds in the background oftentimes cause a lot of static in the background, however I am forced to continue to listen to them because of the aforementioned observation that the non-ambient sound effects are important to playing the game.

I tend to be sensitive to noise clutter so oftentimes listening to music while playing league will fatigue me or sometimes even give me headaches. This effect is compounded if I'm also in a voice chat with people as I play the game, as is often the case. Please add a option to disable ambient sounds separate from the other general sound effects (pings, spells, attacks, etc) so that the player experience can be improved. Just about every other game I have ever seen has this option included, so why not League of Legends?
