In public buildings (ERP) and offices, acoustic comfort is both a regulatory and human factor. Poor sound control affects concentration, communication, and user experience. Standards define performance levels to ensure comfort and intelligibility in all environments.
Why are acoustic regulations important?
Noise influences health, productivity, and social interaction. Regulations therefore define minimum performance levels for reverberation, impact sound and airborne insulation.
Key reference texts
- NF S31-080: acoustic performance in office spaces.
- EN ISO 3382: measurement of reverberation time (RT60).
- Building codes and directives across Europe regulating sound levels in schools, hospitals, and workplaces.
Main acoustic indicators
- RT60: reverberation time, ideal between 0.5 s and 0.8 s depending on use.
- DnT,A: airborne sound insulation between rooms.
- L’nT,w: impact noise level through floors.
- LAeq: average ambient sound level.
Recommended values
- Offices: RT60 ≈ 0.55 – 0.75 s
- Meeting rooms: RT60 ≈ 0.6 s
- Public halls: RT60 ≤ 1 s
Improving compliance
To meet these standards, spaces should include absorbent ceilings, acoustic wall finishes, and adequate spatial zoning. The goal is a controlled sound environment where communication remains clear without excess reverberation.
A holistic design approach
Acoustic quality is now a core component of sustainable building design. Combining efficiency, comfort, and aesthetics, modern acoustic panels contribute to both performance and design coherence.

FAQ
Are acoustic standards mandatory?
Yes, for public and tertiary buildings they are part of legal requirements in most European countries.
How is RT60 measured?
By a certified acoustician using calibrated equipment and standardized procedures (ISO 3382).
Can compliance be achieved without heavy renovation?
Yes. Modular acoustic panels or wall absorbers can quickly improve reverberation without structural work.
