Solving Noise Problems in a Heritage Ballroom
Location: City of Whitehorse, Box Hill, Victoria, Australia

Restoring a heritage ballroom can pose unique acoustic challenges—especially when hard surfaces dominate the space. This was the case at the City of Whitehorse Main Ballroom, where a renovation project aimed to preserve the historic look but initially left out any acoustic treatment. The result was excessive reverberation and poor sound clarity during events.
To resolve this, the Whitehorse Council engaged Acoustic Engineer Mr David Dolly of Acoustic Consulting Australia. After assessing the space, he consulted with Sontext for a sound-absorbing solution that would be both effective and aesthetically appropriate for a heritage setting.
Why Serenity Acoustic Panels Were Selected
Serenity Fabric Acoustic Panels were chosen for the walls due to their superior sound absorption and robust design. The panels were supplied in custom sizes and a 50mm thickness to deliver enhanced performance across multiple frequencies, blending seamlessly with the interior decor.

For the ceiling, the challenge was greater. The ballroom’s high, curved architecture required a panel that could both absorb sound and conform to the shape of the structure. SerenityLite Acoustic Ceiling Panels in 25mm thickness were selected. Their flexibility, lightweight structure, and effective absorption characteristics made them ideal for this curved ceiling installation.
The Outcome
The result was a dramatic improvement in sound clarity and speech intelligibility during events, all while preserving the architectural character of the ballroom. The combined use of Serenity and SerenityLite panels provided an elegant and functional solution to an otherwise complex acoustic issue.
