Church Acoustic Enhancement Design

I need a professionally developed acoustic treatment plan for a large church sanctuary. My priority is to enhance the musical quality we offer every week. We run regular worship services that feature a full band—drums, bass, guitars, keys, multiple vocalists—so the room must flatter contemporary praise music without compromising spoken-word intelligibility.

The space is sizeable, with high hard ceilings, long parallel walls, and a generous volume that currently produces a lively but unfocused wash of sound. I’m after a solution that will give definition to drums and electric instruments, preserve warmth for acoustic sections, and keep the congregation’s singing rich rather than boomy.

I’m looking for a complete, actionable plan that includes:
• Accurate measurement or simulation of current reverberation time (RT60) and frequency-dependent decay.
• A 3-D model (EASE, Odeon, or comparable) showing recommended absorber, diffuser, and bass-control placement.
• Material specifications: type, thickness, mounting method, and square footage for each treatment zone, balanced against aesthetics and existing décor.
• An equipment and materials schedule I can hand directly to installers and budget planners.
• Guidance on minor layout tweaks—stage risers, drum shield, choir or monitor positioning—if those will measurably improve results.
• A concise summary of expected acoustic metrics after treatment so we can verify performance on commissioning.
