Details
This unique structure functions as an acoustic reflector. Made from composite fiberglass, the petals can be positioned to reflect sounds to pre-determined areas of the venue as well as adapt to different types of performance. Designed by ARM Architecture in conjunction with highly experienced German acousticians Müller BBM.
The large audience reflectors weigh approx. 160kgs while the smaller orchestra petals weigh approx. 80kgs. This acoustic reflectors above the stage have replaced the old clear acrylic ‘donuts’. These ‘acoustic petals’ are set in a range of different positions, depending on the music being played. They have been finished in a semi-gloss magenta – matching the colour of the Concert Hall seats chosen by architect Peter Hall.
