New French standard on office acoustics

NF S31- 080, Acoustics – Offices and associated areas – Acoustic performance levels and criteria by type of area, published January 2006, is the first French standard on office acoustics. It is designed as a reference document for clients to express their requirements, as well as a guide-line for office designers.

Nine room types have been defined (personal office, open plan office, meeting room, etc). For each of the rooms, the standard defines three levels of performance: Standard, Efficient and Highly efficient level. For each of the level, a description of the expectable sound environment is made. Finally, a table displays the numerical values to be achieved in order to meet the targeted performance in normal conditions.
NF S31- 080 can be used in specifications like:
“(…) open spaces will be designed according to NF S 31-080, Efficient level, implying a rate of spatial decay of at least 3 dB(A) per doubling of distance, a Total noise level of 45 dB(A)Insulation from internal airborne noise of 35 dB
The standard is issued by the Technical Committee S 30D from AFNOR (French Standardisation Member Body) including acousticians (Peutz, Gamba, etc), clients and end-user organisations (Renault, EDF, etc), quality assessment/risk management (SOCOTEC, APAVE) and representatives from the industry (AMF, Armstrong, Ecophon, Eurocoustics, etc)
