Frequently Asked Questions: Schools & Academies

What is the maximum reverberation time for a school classroom?▾
BB93:2015 requires a maximum unoccupied RT60 of 0.6 seconds in classrooms for pupils aged 7 and above, and 0.4 seconds for pupils with special hearing needs. ANSI S12.60 similarly mandates 0.6 seconds for rooms under 283 m³ and 0.7 seconds for larger spaces.
How does BB93 apply to school building design?▾
BB93 is the UK regulatory standard for school acoustics, setting performance targets for reverberation time, indoor ambient noise level, and airborne/impact sound insulation. It applies to all new-build and refurbished schools in England and Wales, and compliance is a condition of Department for Education funding approval.
What acoustic treatments are most effective in school sports halls?▾
Sports halls typically require impact-resistant absorptive wall panels and suspended acoustic baffles or ceiling rafts to achieve the ≤1.5s RT60 target. Perforated steel or timber wall panels with mineral wool backing provide both durability and absorption. The treatment area should cover at least 50–60% of available wall and ceiling surfaces.
How much does school acoustic treatment cost?▾
Acoustic treatment for schools typically costs 1.5–2.5% of the total construction budget. For a typical primary school classroom, this translates to approximately £2,000–£5,000 for ceiling tiles, wall panels, and carpet. Early-stage acoustic design is far more cost-effective than retrospective remediation.
