How do you soundproof a sports arena?

Sports arenas are built for movement, endurance, and activity, but that is precisely why the acoustic environment often becomes harsh. Sports flooring, high ceilings, large wall surfaces, pull-up bars, goals, balls, and many people in motion create a soundscape where noise and reverberation quickly build up. When sound bounces around the room for a long time, it becomes harder to hear instructions, conversations, and signals, and the environment can become stressful for students, coaches, teachers, and staff alike.

To soundproof a sports hall, the primary focus should be on sound absorption. Sound absorbers reduce sound reflections inside the gym and cause sound to fade more quickly. This is especially important in large spaces where sound can otherwise travel long distances between the floor, walls, and ceiling. A good acoustic solution won’t make the gym silent, but it can make the noise level more controlled and less harsh.

SilentDirect typically recommends starting with the ceiling when sound-absorbing a room. In a sports hall, the ceiling is often the most strategic surface because it is large, relatively unobstructed, and affects the entire volume of the hall. Ceiling absorbers can therefore be the most important basic measure against echo and reverberation. Wall absorbers can then be added to surfaces where sound bounces back across the court, along the long sides, or from the short walls.

It is also important not to confuse sound absorption with sound insulation. If the problem is that sound is too loud inside the hall—that voices and ball sounds echo, or that instructions are difficult to hear—sound absorption is the right approach. If, on the other hand, the problem is that sound is spreading to classrooms, offices, residences, or other rooms adjacent to the gym, sound insulation or vibration damping may be needed as a separate measure.

A sports hall should therefore be assessed based on both the activities taking place there and the building itself. Ceiling height, hall volume, wall materials, usage, type of sport, number of people, and adjacent spaces all influence which solution is most suitable. The goal is a clearer, quieter, and more functional acoustic environment where activities can continue without noise and reverberation taking over.

Less echo and reverberation
Sound fades away more quickly, making the hall less harsh and more pleasant to be in.

Lower perceived noise level
The sounds of balls, footsteps, voices, and whistles do not blend together as strongly in the room. Clearer instructions: Teachers, coaches, and leaders are easier to hear even when several people are active at the same time.

Better work environment
A quieter sound environment can make the gym less stressful for staff, teachers, and instructors.

A more effective school and club environment
Students, children, and athletes have better conditions for listening, focusing, and participating.

More even sound distribution throughout the gym
Ceiling and wall absorbers can reduce harsh reflections from large surfaces and create better balance in the room.

Improved speech intelligibility
When reverberation is reduced, it becomes easier to understand words, signals, and instructions.

Flexible solution tailored to the hall’s needs
Sound absorption can be customized based on ceiling height, wall surfaces, hall volume, and how the space is used.

Sports arenas often have a long reverberation time because they combine a large volume with many hard surfaces. Sounds from balls, shoes, voices, and whistles are reflected off the floor, walls, and ceiling. The longer the sound lingers, the more new sounds mix with residual sounds.

• High ceilings provide a large volume for sound to travel through.
• Hard sports floors reflect both footstep sounds and ball sounds.
• Large wall panels can create distinct side reflections.
• Empty or bare surfaces cause the reverberation to last longer.
• Multiple activities happening at the same time increase the overall noise level.
• Instructions and signals become harder to hear when sound bounces around for a long time.

Proper sound absorption helps sound fade away more quickly. This can result in better speech intelligibility, a calmer experience, and a more functional work environment in the gym.

A sports hall requires an acoustic solution that works well in large spaces with high activity levels, movement, and hard surfaces. We recommend that you start by assessing the hall’s actual acoustic problems and then work from the most effective surfaces toward supplementary measures.

1. Listen to the gym while it’s in use

Don’t start by assessing the hall when it’s empty. A sports hall may seem fairly normal when quiet but become very noisy when classes, teams, or groups are using it. Listen to how voices, balls, shoes, whistles, and instructions sound during activity. Note whether the problem is primarily echo and noise inside the gym, or if the sound also disturbs adjacent rooms.

2. Prioritize ceiling absorbers as a basic measure

SilentDirect typically recommends starting with the ceiling when addressing sound absorption in a room. In a sports hall, this is particularly logical since the ceiling area is large and affects the entire hall volume. PES Ceiling Deep Absorb is suitable when the hall has higher ceilings, greater volume, or longer reverberation time. PES Ceiling can be a more versatile option when broad ceiling-mounted sound absorption is needed.

In larger or more demanding facilities, PES Ceiling Deep Industry or PES Ceiling Industry may also be appropriate where the environment requires a more robust solution. The choice should be based on the hall’s size, installation options, and the severity of the noise problem.

3. Supplement with wall absorbers on reflective surfaces

Once the ceiling is planned, you should turn your attention to the walls. Long wall sections, hard end walls, and surfaces behind goals or along activity areas can contribute significantly to a harsh sound environment. PES Wall Deep Absorb may be suitable where wall surfaces require more sound absorption, while PES Wall serves as a wide wall absorber to reduce harsh reflections.

In more exposed or larger environments, PES Wall Deep Industry or PES Wall Industry may be worth considering. Wall placement should always be planned to accommodate the facility’s use, equipment, safety, cleaning, and open spaces.

4. Assess whether the issue also involves sound insulation

If the noise is primarily disruptive inside the gym, sound absorption is the primary solution. If, however, the noise spreads to classrooms, offices, hallways, residential areas, or other parts of the building, sound insulation may be required. Sound insulation involves reducing sound transmission through building structures, while sound absorption improves the acoustics inside the room.

This is especially important in schools, where a gym is often located near other teaching areas. A gym may need ceiling and wall absorbers for acoustics, while doors, walls, ceilings, or floors may need to be assessed to determine if sound is leaking out.

5. Consider the Hall’s Activities and Installation

Sports halls are used in many ways: for school sports, ball sports, club practices, gatherings, and sometimes events. Therefore, placement and installation must be planned practically. Check the ceiling height, lighting, ventilation, wall fixtures, goals, pull-up bars, cleaning procedures, and other installations before selecting a solution. The absorbers should be placed where they provide acoustic benefits without interfering with the hall’s functionality.

6. Evaluate After Installation

Once the sound absorbers are installed, the gym should be tested under actual use. Listen for speech intelligibility, reverberation, whistling sounds, ball sounds, and the general noise level when multiple people are active. If the hall still sounds too harsh, wall surfaces or particularly vulnerable zones may need additional treatment. In large halls, a combination of ceiling and wall absorption is often more effective than treating only a small area.

Did you know that a sports hall can feel noisy even if each individual sound isn’t extremely loud? The problem is often that the sound lingers for too long. As the reverberation decreases, the hall often becomes easier to use because voices, instructions, and activity become more clearly distinguishable.

For sports arenas, ceiling absorbers are typically the most important element, since the ceiling surface accounts for a large portion of the arena’s volume. Wall absorbers can then be used to reduce harsh side reflections and provide additional absorption where wall surfaces contribute to noise and reverberation.

PES ceiling Deep Absorb is a 100 mm ceiling absorber suitable for situations where a larger space, higher ceiling height, or long reverberation time requires more in-depth sound absorption.

PES Ceiling is a flexible ceiling absorber for spaces where the ceiling surface can be used to reduce reverberation and overall noise levels.

PES Ceiling Deep Industry is an extra-thick ceiling absorber for large, noisy spaces where more absorbent material is needed.

PES Ceiling Industry is a robust ceiling absorber for harsher environments where clatter, echoes, and general noise levels need to be reduced.
