Case Study: Acoustic Transformation for a Catholic Church in Kuala Lumpur
Project Overview
A Catholic church in Kuala Lumpur engaged Acoustics Asia Builders after years of struggling with excessive echo, poor speech clarity, and difficulty hearing sermons, music, and live bands.
The hall’s original reverberation time (RT) measured 4–5 seconds, far above the ideal 1.5–2.0 seconds recommended for worship spaces. This made services tiring to follow, especially for elderly congregants and children.
To support the church’s mission and budget as a non-profit organisation, we designed a cost-efficient, wellness-focused acoustic solution using fabric-wrapped ceiling panels, installed without disrupting weekly worship.
Client’s Challenges
The client faced three major issues:
1. Excessive Reverberation
The long RT caused sermons, prayers, and choir performances to become blurred and difficult to understand.
2. Live Music Sound Problems
The church regularly hosted live bands for contemporary worship. Instruments — especially drums, guitars, and keyboards — created harsh reflections that overwhelmed vocals.
3. Budget Limitations
Being a non-profit community organisation, the church needed:
- An effective yet economical solution
- Safe materials
- Minimal downtime, with installation outside service hours
Our Acoustic Assessment
Using RT60 measurement tools and on-site analysis, we found:
- RT60 (Original): 4–5 seconds
- Highly reflective surfaces: concrete, plaster, glass
- No existing sound-absorbing materials
- Flutter echoes & long decays in the mid–high frequencies
- Sound hotspots around the altar and musician zone
These findings guided our design approach, focusing on reducing reflections, improving intelligibility, and balancing frequency response.
Our Solution & Design Approach
1. Fabric-Wrapped Acoustic Ceiling Panels
We proposed a ceiling-mounted acoustic treatment using non-toxic, eco-friendly fabric panels, selected for:
- High absorption (NRC 0.8–0.9 depending on thickness)
- Neutral, elegant colours suitable for sacred architecture
- Durable, easy-maintenance design
2. Strategic Placement for Maximum Coverage
Panels were arranged across the nave and altar area, angling them to break parallel reflections and minimise echo paths.
This layout specifically targeted:
- Mid–high frequencies (critical for speech clarity)
- Direct reflections from the band
- General reverberation across the hall
3. Acoustic Expertise Provided as a Complimentary Contribution
To support the church’s financial constraints, we charged only for:
- Material
- Labour
- Transportation
All acoustic design, testing, and consultancy were provided at no additional cost as our contribution to the community.
Results
Measured Acoustic Improvement
| Acoustic Parameter | Before | After |
|---|---|---|
| Reverberation Time (RT60) | 4–5 seconds | 1.4–1.8 seconds |
| Speech Clarity | Poor | Clear, balanced, comfortable |
| Live Band Performance | Harsh, overwhelming | Controlled, warm, well-defined |
What the Client Reported
- Congregants instantly noticed clearer sermons
- Elderly members could finally hear without strain
- Music felt “full but not noisy”
- Overall experience became calmer, warmer, and more welcoming
Visuals From the Project




Why This Solution Worked
- Rooms with high ceilings & hard surfaces need heavy mid-high absorption
- Ceiling placement treats the largest reflection path without altering the architecture
- Fabric-wrapped panels provided both performance and aesthetic harmony
- Reducing RT to ~1.5 seconds created the ideal balance between spoken word and music
