Mandatory Acoustic Requirements

1.

NRA (arrêté du 30 juin 1999) sets mandatory acoustic requirements for new residential buildings — DnT,A >= 53 dB between dwellings

2.

Arrêté du 25 avril 2003 defines acoustic requirements for non-residential buildings (ERP) including RT60 targets for classrooms

3.

Code de la Construction articles R111-4 to R111-4-2 establish the regulatory framework for building acoustics

4.

RE 2020 (Réglementation Environnementale 2020) includes acoustic performance as part of environmental building assessment

Green Building Certifications

These voluntary certifications include acoustic performance credits and are increasingly the market standard for premium France developments.

Common Mistakes by France Architects

!

Confusing NRA requirements (in situ DnT,A values) with laboratory Rw values — the NRA requires field-measured performance which is typically 3-5 dB lower

!

Not accounting for the arrêté of 2003 reverberation time requirements for ERP (public buildings) — schools, hospitals, and offices have specific RT60 targets

!

Overlooking the "bruit de choc" (impact noise) requirement of L'nT,w <= 58 dB which is stricter than many other European codes

Frequently Asked Questions: France Acoustics

What does the NRA require for French buildings?▾
The NRA (arrêté du 30 juin 1999) requires: airborne sound insulation DnT,A >= 53 dB between dwellings, impact noise L'nT,w <= 58 dB for floors, facade insulation DnT,A,tr >= 30 dB (or higher in noise-exposed zones), and equipment noise limits for HVAC (LnAT <= 30 dB(A) in habitable rooms). These are measured values — the attestation acoustique is required at building completion.
Is acoustic testing mandatory in France?▾
Yes, France is unique in requiring mandatory acoustic testing (mesures acoustiques in situ) for all new residential buildings since 2013. The "attestation de prise en compte de la réglementation acoustique" must be issued by a qualified acoustician at project completion. Non-compliance can result in construction defect claims (vice caché) under the 10-year décennale guarantee.
What are HQE acoustic requirements?▾
HQE (Haute Qualité Environnementale) Cible 9 "Confort Acoustique" has three levels: Base (NRA compliance), Performant (exceeding NRA by 3 dB), and Très Performant (exceeding NRA by 6 dB). It covers: sound insulation between spaces, equipment noise, facade insulation, and room acoustic quality (RT60). The Performant level is typically required for HQE certification.
How does RE 2020 affect acoustic design?▾
RE 2020 (Réglementation Environnementale 2020) does not directly modify acoustic requirements but its emphasis on lightweight construction and natural ventilation creates acoustic challenges. Timber-frame buildings promoted by RE 2020 require careful acoustic detailing to meet NRA requirements. The "confort d'été" (summer comfort) provisions encouraging natural ventilation conflict with facade acoustic insulation requirements.
