COMPARISON BETWEEN SOUND REDUCTION INDEX MEASUREMENT TECHNIQUES

Fausti, P.; Secchi, Simone

The Sound Reduction Index of a partition can be measured according to the method described by ISO 140-3. This measurement technique prevents the possibility of discerning between direct transmission through the partition and transmission through the lateral structures of the rooms. The paper reports the preliminary results of a research project aimed at comparing three different methods of SRI measurement: the traditional method, the intensimetry method and a method based on the measurement of the vibration velocity of the partition. The comparison makes it possible to explain the drop in the performance of a specific double partition at certain frequencies.

Abstract:	The Sound Reduction Index of a partition can be measured according to the method described by ISO 140-3. This measurement technique prevents the possibility of discerning between direct transmission through the partition and transmission through the lateral structures of the rooms. The paper reports the preliminary results of a research project aimed at comparing three different methods of SRI measurement: the traditional method, the intensimetry method and a method based on the measurement of the vibration velocity of the partition. The comparison makes it possible to explain the drop in the performance of a specific double partition at certain frequencies.
