This week’s submission comes to us from Jim Hunt. Here’s his set up:

“In a continual surge to find something different and unusual program for our website, I came across this fascinating video that tackles a question many of us have silently wondered about: how the acoustics in the iconic Sydney Opera House actually work — and why such a visually striking building can be just as intriguing in sound as it is in form.”

Go inside the Sydney Opera House Concert Hall with JK Power, the building’s account manager, and see how one of the world’s most iconic venues finally found its voice.

This behind-the-scenes tour explores the $300M renovation that transformed the hall’s acoustics, including adjustable acoustic petals, retractable wall panels, programmable stage geometry, and architectural refinements that allow 2,664 seats to share one coherent sonic experience.
