McKinnon Scout Group Acoustic Upgrade

The Challenge

Community halls and scout centres are designed to bring people together. They host meetings, training sessions, social events, youth activities, and celebrations. But across Australia, many of these large multipurpose halls share the same problem: excessive echo, uncontrolled noise, and poor speech clarity. This was exactly the challenge facing the McKinnon Scout Group. Like many large halls and community centres, their space was practical, durable, and flexible — but acoustically difficult. Hard wall surfaces, high ceilings, and open floor areas created a highly reverberant environment that made communication challenging and noise control nearly impossible. This case study explores how SoundFix Acoustics delivered a quick, effective acoustic upgrade using strategically designed ceiling acoustic panels and wall panels — achieving measurable echo reduction and restoring clarity to the space.

If your community hall, scout group venue, sports pavilion, church hall, or multipurpose centre suffers from excessive echo, long reverberation time, or uncontrolled noise, the solution does not require rebuilding your space. It requires the right acoustic strategy. SoundFix Acoustics provides expert assessment, tailored acoustic design, and professional installation of ceiling acoustic panels and wall panels to deliver measurable echo reduction and effective noise control.

The Solution

Large halls are some of the most challenging environments for acoustic control. The McKinnon Scout Hall had all the common characteristics that create acoustic problems:

– High ceiling

– Hard reflective walls

– Minimal soft furnishings

– Large open floor area

– Parallel surfaces that bounce sound energy repeatedly

When sound reflects off hard surfaces instead of being absorbed, it builds up in the room. Voices overlap. Instructions become unclear. Background noise rises quickly. The result is long reverberation time and poor noise control.

Before treatment, reverberation measurements confirmed the issue. Mid-frequency reverberation times — critical for speech intelligibility — were significantly above recommended levels for community halls.

In practical terms, this meant:

– Leaders had to raise their voices

– Group instructions were difficult to hear

– Noise levels escalated quickly during activities

– The space felt loud and chaotic during busy sessions

For a scout group environment – where communication, safety, and engagement are essential – this was more than a comfort issue. It was a functional problem. Like many community centres, the building was structurally sound. The issue was not the layout or construction – it was acoustics.

The Installation

The goal was not soundproofing. The hall needed sound absorption — not sound blocking.

SoundFix Acoustics developed a tailored acoustic treatment plan focused on:

High-performance ceiling acoustic panels

Even distribution of sound absorption across the space

Minimal visual disruption

Why Ceiling Acoustic Panels?

In large halls, the ceiling is the dominant reflective surface.

Sound energy travels upward and reflects back down, creating prolonged reverberation. By installing ceiling acoustic panels, we intercept reflected sound at its primary source, dramatically reducing echo build-up.

Ceiling acoustic panels are particularly effective for:

Large community halls, Scout halls, Church halls, Sports centres, Multipurpose venues

By targeting the ceiling first, we addressed the core acoustic behaviour of the room.

The Outcome

The results were both immediate and measurable. Post-installation reverberation testing confirmed a substantial reduction in reverberation time across speech-critical frequencies. This translated into real-world improvements.

Leaders and instructors no longer needed to shout. Instructions became clear and understandable, even during active sessions.

Background noise levels stabilised. Sound no longer built up uncontrollably during group activities.

The space felt calmer and less overwhelming. This is particularly important for children and individuals sensitive to noise.

In scout halls and community venues, clear communication is critical. Effective echo reduction enhances safety and coordination.

Improved acoustics make environments more accessible for people with hearing challenges, neurodivergent participants, and older adults.

By installing ceiling acoustic panels and wall panels correctly, the hall shifted from an echo-filled, high-reverberation space to a controlled, usable, and comfortable community venue.

Before-and-After Acoustic Results

Before installation

Average RT60: 2.01 seconds

Excessive echo across key speech frequencies (500 Hz–2 kHz)

Echo is not just an inconvenience. In large halls and community centres, it changes how people interact, communicate, and participate.

After installation

Average RT60: 0.92 seconds

If your community hall, sports centre, or large venue suffers from excessive echo, poor speech clarity, or uncontrolled noise, the solution is not to redesign the building — it’s to address the acoustics.

To see how we can transform your venue, get in touch with SoundFix Acoustics for an acoustic assessment and discover how the right solution can make your space work the way it was always meant to.

Community spaces are built for people—and people need to hear, understand and feel comfortable within them. Whether it’s a multicultural centre, place of worship, school, office or healthcare facility, poor acoustics can undermine even the most thoughtfully designed environment.
