Audio emanates through the mural wall from three locations -- the far left, the far right, the middle. The volume of the audio is faint: from a distance one may not hear it, or not hear it clearly. Only if you move closer can you hear the audio clearly. Depending on where you stand along the 45' length of the mural, you hear the different audio tracks mixing together more or less.

To hear the mix of audio as you stand in front of the mural, drag your cursor left/right over the picture below.
