Details
The Sydney Opera House Concert Hall underwent a significant renovation in 2022, aimed at enhancing its acoustics, accessibility, and stage functionality while preserving its iconic status. The project included the replacement of outdated acoustic features with 18 state-of-the-art sound reflectors, designed to optimise sound quality for a variety of performances.
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.
ShapeShift Technologies played a pivotal role in this upgrade by supplying customised ShapeShell™ RT sound deflectors, engineered to deflect and diffuse sound waves for balanced acoustics. These advanced fibre-reinforced panels, often referred to as surfboard-shaped due to their unique design, were meticulously crafted to integrate seamlessly with the architectural aesthetic of the hall. The installation of these deflectors not only enhanced the auditory experience but also maintained the structural and visual harmony of the UNESCO World Heritage-listed building.
