Project Overview: Multipurpose Room Acoustic Treatment at the WellCome OM Center
- Project: Multipurpose Room Acoustic Treatment for a Wellness and Event Hall
- Location: 4242 Lake In The Woods Dr, Spring Hill, FL 34607
- Facility Type: Multipurpose Hall Inside an Integrative Wellness Campus, Hosting Seminars, Yoga, Classes, Weddings, and Speakers
- Client: WellCome OM Integral Healing & Education Center
- Objective: Reduce Broadband Reverberation from 3+ to ~1.5 seconds
- Scope: Site Reverberation Analysis, Custom Acoustic Wall Panels, Suspended Ceiling Clouds, Two-Day Install
Commercial Acoustics was brought in to fix the multipurpose hall at the WellCome OM Integral Healing & Education Center, an integrative wellness campus in Spring Hill, FL that holds a 4.7-star reputation across more than 70 community reviews. The hall sees real range of use across a single week: yoga, meditation, Pilates, Tai Chi, healthy cooking classes, weddings, conferences, and the speaker series the center is best known for. The room had to perform across all of those use cases, and on day one it was failing every one of them on the same problem.
The treatment plan came in at just under 100 custom acoustic panels, a mix of wall-mounted absorbers and suspended ceiling clouds, sized and located to bring broadband reverberation into the 1.5-second range without disrupting the architectural design or the lighting layout. The full install ran in two days. For another reverb-driven retrofit at a Florida event venue, see our clubhouse acoustic panel treatment at Country Club of Ocala.
Acoustic Challenges in a Multipurpose Wellness Hall
- Measured Reverberation: Over 3 seconds broadband RT60, roughly double the target
- Reflective Architecture: Tall ~20 ft ceiling, hard floor, drywall perimeter, no soft goods
- Use Range: Speaker Series, Yoga and Movement Classes, Live Music, Catered Weddings, Book Signings
- Constraint: Treatment had to sit high enough to not disrupt the architecture
Multipurpose halls are the hardest single room type to acoustically tune because the right reverberation depends on what is happening in the space at the time. A dining environment generally lives in the 0.7–1.1 second range. A speaking engagement wants closer to 1.0–1.5 seconds for clean intelligibility. A yoga or movement class can take a touch more liveness without losing function. Our room acoustics calculator walks through the Sabine math behind these targets and lets you model treatment quantities from a room’s surface areas and finishes.
Above about 2 seconds of broadband RT60, every use case in that list breaks at the same time. Speech intelligibility falls apart, amplified PA loses clarity, and dining conversation forces guests to lean across the table. The WellCome OM hall came in over 3 seconds, which means even a strong wireless mic was working against the room. The pragmatic target for a hall this size and this varied is around 1.5 seconds, with the additional constraint that low-frequency RT60 should not exceed 2 seconds at any 1/3-octave band.
Solution: Custom Acoustic Wall Panels and Ceiling Clouds
- Panel Count: Just under 100 custom-fabricated panels
- Mix: Wall-Mounted Acoustic Absorbers Plus Suspended Ceiling Clouds
- Placement: High on the Walls and Below the Ceiling, Above Lights and Vents
- Install Method: Scissor Lift for Ceiling Cloud Suspension at Roughly 20 Feet
The wall absorbers came from our acoustic absorption panel line, custom-sized to fit the available wall area without crowding the windows or branded signage. The ceiling clouds came from our ceiling cloud line, suspended on aircraft cable at a height that lined up with the existing pendant fixtures so the room reads as architectural rather than retrofitted.
The panel quantity was sized off our initial reverberation analysis and an offsite Sabine calculation. Wall absorbers handle most of the mid-frequency speech band, and the suspended clouds do the heavy work in the lower frequencies where amplified PA and live music push the most energy. Cloud absorption is also more efficient per square foot than wall treatment in tall rooms, because the panel sees both the floor reflection and the ceiling reflection.
Results: Reverb Cut From 3+ Seconds for Speakers, Classes, and Events
- Pre-Treatment RT60: Over 3 seconds broadband
- Post-Treatment Target: ~1.5 seconds, inside the multipurpose-hall window
- Install Window: Two days, including cloud suspension and wall mounting
- Use Coverage: Speaker Series, Yoga, Pilates, Live Events, Weddings
The first booking after install was a scheduled speaking engagement, which is the use case most punished by long reverberation. The room held the speaker cleanly without staff needing to reposition the PA or push the gain. From a venue-operations perspective, the treatment unlocked the booking calendar that the prior reverb time had effectively capped: events the WellCome OM staff would have steered to outdoor space were back on the table inside the hall. For another reverb-driven country club retrofit, see our golf clubhouse acoustics upgrade at The Concession.
Conclusion: Acoustic Treatment for Multipurpose Wellness and Event Halls
The takeaway for venue operators running a multipurpose hall: aim for a 1.5-second broadband target and watch the lower octaves carefully, because that is where amplified speech and live music live. The right tool mix is almost always wall absorbers for mid-band speech plus ceiling clouds for low-end energy, sized off a real reverberation measurement rather than a pure model. The WellCome OM Center is a strong example of what a small, well-designed acoustic package can do for a venue that earns its reputation on hosting people well.
Commercial Acoustics provides reverberation testing, panel design and fabrication, and installation for multipurpose halls, wellness centers, houses of worship, banquet rooms, and event venues nationwide.

FAQs: Multipurpose Room Acoustics and RT60 Targets
What RT60 should a multipurpose room target?
Aim for around 1.5 seconds broadband, with low-frequency RT60 staying under 2 seconds at any 1/3-octave band. Dining rooms tune lower at 0.7 to 1.1 seconds; speaker-only rooms hit 1.0 to 1.2. A multipurpose room compromises across all of them.
Is acoustic treatment the same as soundproofing a multipurpose room?
No. Soundproofing blocks sound transmission between rooms with mass and isolation. Acoustic treatment cuts reverberation inside the room with absorption. Multipurpose halls almost always need the second, and only some need the first.
How many panels does a multipurpose hall need?
A typical mid-size hall with hard finishes and a tall ceiling lands between 60 and 120 panels, mixing wall absorbers and ceiling clouds. WellCome OM came in at just under 100 panels to bring broadband RT60 from over 3 seconds into the 1.5-second range.
Why use ceiling clouds in addition to wall panels?
Suspended clouds see both the floor reflection and the ceiling reflection, so they absorb more per square foot than wall mounts in tall rooms. They also do better at the low frequencies where PA and live music live, which is the band that breaks first in multipurpose halls.
