Gymnasium Acoustic Panels for a Charter School: Classical Preparatory School

• Project: Acoustic Treatment for Gymnasium, Dining Rooms & Music Room
• Address: 12830 Shady Hills Rd, Spring Hill, FL 34610
• Facility Type: K-12 Charter School
• General Contractor: In-house Facilities Team with Commercial Acoustics
• Objective: Reduce reverberation & improve sound clarity in key student areas
• Scope: 4,000 sq. ft. of wall panels & 120+ ceiling-mounted acoustic panels

Classical Preparatory School, located just north of Tampa, is a charter school rooted in a classical liberal arts curriculum. As the school expanded enrollment and programming, the administration sought to improve acoustical performance in key student spaces where echo and reverberation were disrupting communication and focus.

Commercial Acoustics was brought in to design and install tailored acoustic solutions across the gymnasium, two dining halls, and a newly converted music room. Each area presented unique challenges—from massive open volumes to limited wall space—but was treated with a strategic mix of wall-mounted and ceiling-mounted acoustic panels to reduce reverberation and improve speech clarity.

With more than 4,000 square feet of acoustic materials installed, the transformation was not only measurable in terms of decibel reduction, but also immediately felt by staff, students, and visitors across campus.

• Surface Materials: Painted CMU, hardwood floor, exposed joists
• Ceiling Height: Over 30 feet with metal decking & joists
• Wall Availability: Ample wall space on three sides for treatment
• Acoustic Problem: Reverb times exceeded 4.0 seconds

The gymnasium at Classical Preparatory was a textbook example of an acoustical challenge—an expansive volume of space surrounded by hard, reflective surfaces. Three of the four walls were constructed with painted concrete masonry units (CMU), while the fourth featured glass. The floor was hardwood sports surfacing, and the ceiling was unfinished, leaving exposed metal joists and decking overhead.

With no carpeting, drapery, or other absorptive surfaces present, the space produced reverberation times over 4 seconds—well above acceptable levels for speech or instruction. The gym hosted physical education classes, assemblies, and informal meetings, but intelligibility and comfort were consistently compromised due to excessive echo.

Despite having ample wall space for treatment, the school wanted to preserve one wall dedicated to banners, which meant the acoustic design had to account for visual and functional priorities as well as sound performance. That balance would inform the strategy in the next phase of the project.

• Panel Type: 4’x8’x2” monolithic acoustic wall panels
• Mounting Method: Direct-wall application with adhesive & impalers
• Location Strategy: Three perimeter walls only, preserving banner wall
• Result: Reverb time reduced by approximately 65%

To tackle the excessive reverberation in the gym, Commercial Acoustics specified large-format 4’x8’x2” acoustic wall panels. These monolithic absorbers are ideal for gyms due to their expansive coverage, high durability, and effective noise reduction. Each panel is designed to absorb mid- and high-frequency sounds — exactly the range that affects speech clarity in large volumes like gyms.

The panels were directly mounted using a combination of construction adhesive and impaling clips, allowing for fast and secure installation across three perimeter walls. The school requested that the fourth wall remain untouched to preserve visibility for banners and awards. Despite this limitation, the treatment design maximized available surface area for absorption.

The result was a dramatic improvement in room acoustics. Reverberation time was cut by over 65%, significantly improving voice projection and speech intelligibility. Teachers, coaches, and students immediately noticed a calmer, more intelligible environment — one better suited for both instruction and activity.

• Room Sizes: Significantly smaller than the gymnasium
• Mounting Approach: Ceiling-mounted 2’x4’ & 4’x4’ acoustic panels
• Wall Space: Limited wall availability prompted ceiling-first strategy
• Goal: Reduce clatter during group meals & gatherings

Unlike the expansive gym, the dining rooms at Classical Preparatory presented a different kind of acoustic challenge. These were compact, high-occupancy spaces where students gathered in large numbers, often simultaneously, leading to elevated background noise levels and harsh echo during mealtimes.

Because the rooms featured limited open wall space—due to doors, display boards, and windows—Commercial Acoustics focused the treatment effort on the ceilings. Direct-mounted acoustic panels in 2’x4’ and 4’x4’ formats were selected to fit cleanly within the architecture, following the slope of the ceilings to target buildup areas where sound energy tends to reflect.

This ceiling-first strategy helped preserve visual openness while significantly reducing reverberation. As a result, the dining halls became more comfortable for both students and staff, minimizing auditory fatigue and making conversations easier during busy lunch periods.

• Conversion: Library repurposed into a performance & rehearsal space
• Treatment Mix: Panels installed on both ceilings & upper walls
• Performance Target: Lower reverb threshold than general classrooms
• Material Used: Over 120 ceiling panels across dining & music spaces

After seeing the success of the gym and dining hall treatments, Classical Preparatory extended its acoustical improvements to the school’s new music room—formerly the library. This newly repurposed space was designed for choir, band, and ensemble rehearsals, where acoustics are particularly critical for performance and instruction.

Because music rooms demand lower reverberation times than multipurpose or dining areas, the design called for a more aggressive treatment layout. Commercial Acoustics installed a combination of acoustic panels on both the ceiling and upper wall sections, optimizing sound absorption at the most reflective points in the room.

Across both the dining and music spaces, over 120 acoustic ceiling panels were used to reduce echo and control sound energy. In the music room specifically, the result was a more refined acoustic environment that supports clarity, tonal accuracy, and focused rehearsals—key components of a high-functioning music education program.

• Reverb Reduction: 65–70% average decrease across treated spaces
• Instructional Clarity: Teachers report improved speech intelligibility
• Student Focus: Noticeably quieter environments during peak use
• Design Integration: Treatments installed with minimal visual disruption

The acoustic improvements at Classical Preparatory School were both measurable and transformative. In the gymnasium alone, reverberation times dropped by over 65%, while dining halls and the music room saw nearly 70% reductions. These changes made an immediate difference in the day-to-day experience for students and staff.

Teachers noticed better clarity during instruction, reduced vocal strain, and improved classroom engagement. In high-traffic areas like cafeterias, background noise dropped dramatically, allowing for more pleasant and less chaotic interactions among students. The music room now supports rehearsals with the tonal precision and clarity essential to music education.

Importantly, these functional upgrades were made without sacrificing the design intent of the spaces. Sound-absorbing panels were color-matched and cleanly integrated, maintaining architectural integrity while solving critical sound issues. The result was a quieter, more focused learning environment throughout the school.

For architects and general contractors working on school projects, proper acoustic design is essential for creating effective learning spaces. At Classical Preparatory School, the integration of gymnasium acoustic panels and ceiling treatments in multipurpose rooms demonstrates how sound control can be both functional and visually harmonious.

From the early consultation phase through installation, our team aligned each treatment with the unique acoustic needs and architectural constraints of the space. Whether you’re planning new construction or retrofitting an existing facility, Commercial Acoustics offers proven solutions to optimize sound without compromising design.
