Church Acoustics: When RT60 Goes From 'Cathedral' to 'Unusable'
Cathedral RT60 of 8+ seconds is acoustically magnificent and completely unintelligible. Here's how to design worship spaces that serve both organ music and the spoken word.
Acoustic Design in Listed Buildings — Improving Acoustics Without Touching the Fabric
Listed building constraints prohibit permanent alterations to historic fabric, but acoustic problems still need solving. This guide covers reversible interventions — freestanding panels, tension wire systems, secondary glazing, electronic enhancement — with case studies from churches, courtrooms, and galleries.
Acoustic Design for Mosques, Churches, and Synagogues — Conflicting Requirements Resolved
Worship spaces face an irreconcilable acoustic conflict: speech requires short RT60 for intelligibility, while music and chanting require long RT60 for reverberance. This guide covers mosque dome echo physics, church parallel wall flutter, synagogue variable occupancy, RT60 targets, heritage constraints, and a worked example for a 500 m³ mosque with dome.
Why Your Church Has Terrible Speech Intelligibility — And What STI Actually Measures
The average historic UK church has RT60 of 3.5–5.0s. The human voice requires STI ≥ 0.45 to be understood. At RT60 > 2.5s, STI drops below 0.45 without a PA system. Here is the physics and the fix.
