Quick answer: Sports halls must achieve a reverberation time of no more than 2.0 seconds (Tmf) under Building Bulletin 93 (BB93). To hit that target, you need impact-resistant, Class A sound-absorbing panels fixed to upper walls and end walls, covering roughly 30–40% of the room's surface area. ZEN Impacta is designed specifically for this environment: reinforced for ball strikes, fire rated, and compliant with BB93 out of the box.
Why sports halls are acoustically difficult
Sports halls combine almost every factor that drives reverberation up: large internal volume, hard floors, hard walls, hard ceilings, minimal soft furnishings, and constant high-energy activity. Sound bounces freely between parallel surfaces with almost nothing to absorb it.
The result is excessive reverberation that makes instructions hard to follow, raises pupil and staff stress levels, and creates a chaotic atmosphere. For pupils with sensory processing differences or hearing impairments, a reverberant sports hall is not just uncomfortable, it can prevent meaningful participation in PE altogether.
BB93 compliance: the standard you need to meet
Building Bulletin 93 (BB93) is the DfE's acoustic design standard for schools. For sports halls, it sets a maximum mid-frequency reverberation time of 2.0 seconds (Tmf).
Failing to meet this standard can:
- breach planning or DfE compliance conditions on new builds and refurbishments
- undermine inclusive education commitments, particularly for SEN pupils
- expose the school to challenge if acoustic performance is documented in a condition survey
BB93 compliance is not just a box-ticking exercise, it reflects a minimum threshold for safe, productive use of the space.
Key specification criteria for acoustic panels in sports halls
Not every acoustic panel is suitable for a sports hall. The specification criteria are more demanding than for a classroom or office:
- Impact resistance: panels must withstand repeated ball strikes and incidental physical contact without deforming or shedding material.
- Class A sound absorption: effective particularly in the 500–2,000 Hz range, where speech and sport noise concentrate.
- High-level wall fixing: panels should be mounted above the activity zone to reduce tampering and obstruction risk.
- Fire rating: Class 0 or Euroclass B as a minimum for use in school buildings.
- Durable, cleanable surface: wipeable finishes withstand the cleaning regimes expected in school sports facilities.
The ZEN Impacta acoustic panel meets all five criteria. It carries a reinforced face for impact resilience, an NRC of 0.90 or above (Class A), is available in custom colours and sizes, and is both fire rated and surface-washable.
Where to install panels in a sports hall
Placement matters as much as the panel itself. The key zones to treat are:
- Upper side walls: absorbing early reflections here produces the greatest reduction in reverberation time per panel installed.
- End walls: long axial reflections between parallel end walls are a major contributor to excessive reverberation in rectangular halls.
- Ceiling (suspended baffles or rafts): useful for very high-ceilinged spaces where wall area alone is insufficient. See ZEN Baffle for a ceiling-hung option.
Avoid floor-level mounting: panels close to the activity surface are exposed to the highest impact risk and are most likely to be damaged or removed.
For halls with complex geometry or adjacency to classrooms, the full acoustic solutions range includes complementary products that can be combined for a whole-room treatment plan.
How much coverage do you need?
As a starting benchmark, treating around 30–40% of the total surface area with Class A panels is typically sufficient to bring a standard rectangular sports hall within the BB93 2.0-second limit. The precise figure depends on room volume, ceiling height, and existing hard-surface finishes.

How acoustic treatment improves pupil and staff wellbeing
The case for acoustic treatment extends well beyond regulatory compliance:
- Clearer verbal instruction during PE reduces injury risk and improves learning outcomes.
- Lower ambient noise reduces anxiety and sensory overload for pupils with SEN, ADHD, or hearing differences.
- Reduced vocal strain protects teacher and coach vocal health over a full working day.
- A calmer acoustic environment supports positive behaviour and reduces the escalation cycle where pupils raise their voices to be heard.

Frequently asked questions
What reverberation time does BB93 require for school sports halls?
BB93 sets a maximum mid-frequency reverberation time (Tmf) of 2.0 seconds for sports halls. This is measured across the 500–2,000 Hz octave bands. Rooms that fail to meet this limit do not comply with DfE acoustic design standards for educational buildings.
What acoustic panels are suitable for sports halls?
Panels for sports halls must be impact resistant (able to withstand ball strikes), Class A sound-absorbing, fire rated to at least Class 0 or Euroclass B, and mounted high enough on the wall to avoid the primary activity zone. The ZEN Impacta is built to this specification and is one of the few panels designed explicitly for school sports environments.
How many acoustic panels does a sports hall need?
As a general rule, covering 30–40% of the total surface area with Class A panels brings most standard rectangular sports halls within the BB93 2.0-second limit. The exact quantity depends on room volume, ceiling height, and existing finishes. A free acoustic assessment will give you a room-specific figure.
Where should acoustic panels be positioned in a sports hall?
Upper side walls and end walls are the most effective locations. They absorb early reflections and control long axial reverb without placing panels where they are vulnerable to ball damage. Ceiling baffles or rafts can supplement wall panels in particularly high or wide spaces.
Do sports hall acoustic panels need to be fire rated?
Yes. Panels used in school buildings must meet Class 0 (national classification) or Euroclass B (European classification) fire rating as a minimum. This is a mandatory requirement under Building Regulations Approved Document B and should be confirmed in any product specification before installation.
Can acoustic panels help SEN pupils in sports halls?
Yes. Excessive reverberation is particularly disorienting for pupils with sensory processing differences, hearing impairments, or ADHD. Bringing the hall within BB93 limits reduces auditory overload, makes verbal instruction clearer, and supports meaningful participation in PE. Acoustic treatment is increasingly treated as part of inclusive design, not just noise control.
