Background:

Amputees Queensland is a non-profit foundation dedicated to supporting individuals who have undergone amputations. The organisation provides a welcoming and supportive environment for amputees and their families. However, the acoustics within their meeting hall had become a significant challenge. The reverberation within the space was excessive, leading to poor speech intelligibility and discomfort during group meetings and activities.

Problem:

Prior to treatment, the hall’s acoustic environment was negatively impacted by its high reverberation time (RT60), measured at approximately 4.5 seconds. Such long reverberation times are undesirable in spaces designed for group interaction, as they can lead to a noisy, echo-filled environment that makes communication difficult. The administrators at Amputees Queensland were concerned that the acoustics were affecting the ability of members to hear and engage effectively during meetings.

Audio recording before treatment:

Solution:

Sydney Acoustics assessed the space and proposed a solution. After a thorough evaluation, the team recommended installing Autex 25mm Thick Quietspace Panels in white, a versatile and highly effective acoustic treatment solution. These panels are designed for a range of applications, providing excellent sound absorption and a modern aesthetic.

The panels were directly fixed to the existing ceiling substrate, ensuring that the treatment would be both efficient and discreet. A total of 60 square meters of sound-absorbing panels were installed across the ceiling, strategically placed to optimise their effect on the reverberation within the room.

Results:

The impact of the acoustic treatment was immediately noticeable. Post-installation measurements revealed a significant reduction in the reverberation time, dropping from 4.5 seconds to 1.7 seconds. This dramatic improvement created a much more comfortable environment for speech and communication.

Lynda, the administrator for Amputees Queensland, expressed her amazement at the transformation. “The difference is remarkable,” she said. “It feels like a completely different space now. We’re looking forward to seeing how the next member group meeting goes, with everyone able to hear each other clearly and without the usual echo.”

Audio recording after treatment:

Conclusion: The successful installation of acoustic treatment at Amputees Queensland Hall demonstrates the importance of addressing acoustic issues in community spaces. By working with Sydney Acoustics and utilising high-quality Autex Quietspace panels, the foundation has significantly improved the functionality and comfort of their meeting space, ensuring a better experience for all members.
