Explore a Chinese opera stage through Herwin Gunawan’s architectural and acoustic perspective. This short video invites reflection on how stage form, overhead enclosure, and openness to the audience relate to sound projection, listening experience, and cultural performance.
How can building physics support a better workplace? Herwin Gunawan introduces the role of heat, air, moisture, sound, and light in office design, connecting environmental conditions with occupant comfort, well-being, and the conditions people need to work effectively.
See how ALTA Integra uses an acoustic camera to investigate sound leakage in building partitions. Combining a 64-microphone array with visual imaging, the system helps the acoustic team locate potential leakage paths and communicate findings to support targeted inspection and corrective work.
How can the sound of a worship space complement its architecture?
