The facade sound insulation measurements method is standardized in ISO 16283-3, which is being revised. The standard includes two measurement methods: the element method and the global method. For the global sound insulation of a façade, the standardized level difference, D2m,nT is used. This level difference is standardized to a reference value of the reverberation time, T0, in the receiving room. For dwellings, T0 is equal to 0.5s. This paper aims to evaluate the influence of the reverberation time (T) correction of the receiving room, with respect to the reference value T0, at the variation of the T value, itself. The results of measurements on site in receiving rooms with different volume and different reverberation times are compared.

Abstract
The facade sound insulation measurements method is standardized in ISO 16283-3, which is being revised. The standard includes two measurement methods: the element method and the global method. For the global sound insulation of a façade, the standardized level difference, D2m,nT is used. This level difference is standardized to a reference value of the reverberation time, T0, in the receiving room. For dwellings, T0 is equal to 0.5s. This paper aims to evaluate the influence of the reverberation time (T) correction of the receiving room, with respect to the reference value T0, at the variation of the T value, itself. The results of measurements on site in receiving rooms with different volume and different reverberation times are compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
