EN ISO 11957:1996

EN ISO 11957:1996 is a standard published by the European Committee for Standardization (CEN). Its full title is "Acoustics - Determination of sound insulation performance of cabins - Laboratory and in situ measurements (ISO 11957:1996)". This standard covers: This International Standard specifies a laboratory method (clause 6) and in situ method (clause 7) for the determination of the sound insulation performance of sound-protecting cabins. The sound insulation performance is the reduction in sound pressure level or sound power level afforded by the cabin. The methods are applicable to cabins with a small leak ratio (q ¿ 2%). This International Standard is applicable to a complete cabin only and not to the individual components from which it is made. NOTE 1: Sound insulations for cabin components such as wall elements, doors, windows, silencers, etc. should be measured according to other relevant standards. Requirements for the test environment in the laboratory are based on those given in ISO 3741.
