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.
Description
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)
