Irritating High Pitched Sound in Lab (Ambient Sound)

When you enter the Labyrinth (and the similar map I believe), there is a high pitched sound that reoccurs that sounds like a small dog whining. It's not a part of the music or sound effects, but a part of the Ambient Sound. The sound is so irritating that I only run Lab, when I have to for each character, and often just turn off the sound completely, which makes some things more difficult. (It's not just me, and I had my hearing tested last month.)

I generally enjoy the ambient sounds in the game, but not that one. Would it be possible to remove that sound out of the ambient sound? I'm sure anyone who is sensitive to that kind of sound would appreciate it.
