Sound Diffusers in a Worship Space: Hyde Park United Methodist Church

• Project: Acoustic Treatment of Renovated Worship & Music Venue
• Address: 500 W Platt St, Tampa, FL 33606
• Facility Type: Church Worship Space in Multipurpose Center
• Client: Hyde Park United Methodist Church
• Objective: Improve Sound Clarity for Speech & Amplified Music
• Scope: 33 Wall Panels, 26 Sound Diffusers & a Full-Height Acoustic Curtain

Hyde Park United Methodist Church, a longstanding faith institution in Tampa’s Hyde Park neighborhood, was transforming its Harnish Activity Center into a contemporary worship space designed for a full band, live AV production, and multimedia presentations. With 25-foot ceilings, LVT flooring, and large flat walls, the space was aesthetically impressive—but acoustically problematic.

HPUMC reached out to Commercial Acoustics to identify, design, and implement a solution that would support both speech intelligibility and musical impact. Our solution included a balance of absorptive panels and barrel sound diffusers, plus a heavy acoustic curtain for the rear wall—all tuned to the unique demands of a worship environment featuring amplified instruments and vocal microphones.

• Reverb Time: Exceeded 2.4 Seconds—Unsuitable for Speech Clarity
• Band Configuration: 5 Mics, Drums, Bass, Guitar, Keyboard, All Amplified
• Flooring & Surfaces: LVT, Drywall & Glass Compounded Acoustic Reflections

We began with onsite acoustic testing using Type 1 sound meters and a dodecahedral speaker to measure reverberation. The space clocked in at over 2.4 seconds RT60—twice the acceptable range for worship use. Reflections from the LVT flooring, drywall, and high ceilings made speech unintelligible and music muddy.

With a full amplified band setup, this environment needed more than basic sound absorption. We needed targeted scattering and absorption to tame reflections and control wave behavior across all frequencies.

• Barrel Diffusers: Scattered Mids & Lows for Smoother Sound
• Avoided Over-Absorption: Maintained Energy for Worship Music
• Placement Strategy: Modeled for Hemispherical Diffusion Coverage

Sound diffusers were essential in balancing the acoustic response of the space without making it feel dull or over-treated. We installed 26 curved barrel diffusers, specifically chosen for their ability to scatter mid- and low-frequency energy. This scattering helped eliminate hotspots and uneven reflections while maintaining musical richness and clarity.

Our design team utilized hemispherical diffusion modeling to inform diffuser placement. This ensured a natural and even sound field across the audience area—avoiding harsh reflections while preserving the warmth and fullness critical to amplified worship bands.

• 33 Wall Panels: High-NRC Panels Neutralized Side Reflections
• Rear Curtain: Velvet Curtain Absorbed Backslap Echo
• Visual Coordination: Seamless Integration with AV & Lighting

We installed 33 fabric-wrapped acoustic panels along the side walls of the worship space. These 2-inch thick panels were positioned at critical first reflection points to reduce echo and flutter, particularly from the speaker arrays. Each panel was rated with a high NRC and mounted with Z-clips for a clean, flush aesthetic.

To address reflections behind the stage, we used a full-height acoustic curtain with a dense velvet surface. This allowed us to eliminate harsh rear-wall echoes, known as backslap, without interfering with projector screens or lighting lines. The curtain also added visual texture and flexibility for future space layout changes.

• Sabin Calculations: Designed Absorption to Meet RT60 Targets
• NRC Ratings: Selected Materials Rated 0.85–0.95 Across Key Frequencies
• 3D Modeling: Simulated Sound Paths from All Speaker Locations

Using Sabin’s formula, we calculated how much total absorption was needed to bring the room’s reverberation time into the ideal range for contemporary worship: between 1.2 and 1.5 seconds. Each material—panels, diffusers, and curtain—was chosen for its effectiveness in the 250Hz–4kHz range, where speech and music intelligibility overlap.

We also performed 3D acoustic modeling of the space, simulating sound trajectories from every major speaker zone. This modeling allowed us to refine placement of treatments for maximum impact and ensure that coverage remained consistent throughout the entire seating area.

• Speech Intelligibility: Clear Sermons & Spoken Word from Every Seat
• Music Clarity: Balanced Band Audio with Reduced Muddiness
• User Feedback: Strong Approval from Staff, Musicians & Congregation

Following installation, the sanctuary underwent a noticeable transformation. Spoken word was now intelligible throughout the room, even with background music or band accompaniment. Reflections that previously blurred vocals and instruments were now controlled, allowing each sound source to be heard with clarity.

Feedback from musicians, staff, and the congregation was overwhelmingly positive. Band rehearsals became more efficient, pastors no longer had to repeat themselves, and attendees reported a more immersive and comfortable worship experience overall.

For architects and general contractors, designing a worship space that sounds as good as it looks requires forethought, expertise, and collaboration. In a multipurpose setting like Hyde Park UMC’s, it’s not enough to rely on standard finishes or assume furniture will “soak up” the sound. The acoustic performance must be designed, modeled, and executed with precision.

At Commercial Acoustics, we specialize in custom acoustic solutions for sacred spaces—whether retrofitting an existing sanctuary or designing a contemporary multipurpose venue from the ground up. We manage the process from analysis to installation, ensuring the final result blends seamlessly into your architectural vision while delivering the clarity and warmth your audience expects.

Whether you’re designing for amplified music, spoken word, or a seamless blend of both, the acoustics must elevate the experience—not compete with it. We specialize in shaping environments where every note, every word, and every moment is supported by intentional, high-performance sound design. Reach out to our team and let’s bring clarity, energy, and impact to your next sacred project.
