Interesting Acoustic Wall

I found this acoustic wall by Noshin Khan to be very beautiful, very creative use of material. I just wonder if a proper acoustic study has been done to test its success since steel sheet isn’t recognized as a good acoustic material. Maybe the folds in the beautifully complex form enforce the deflection of sound and stop it from passing to the other side of the wall, which would be very impressive. If it’s still up in AUS I would love to go see it in person!
