The purpose of this work is to assess the accuracy at low frequencies of measurements performed using the default procedure of ISO 140-4 (the same of ISO/DIS 16283-1) in test rooms with volumes greater than 25 cubic meters. About 100 previous measurements were analyzed, referring to in-situ airborne sound insulation from 50 to 5000 Hz.

Abstract
The purpose of this work is to assess the accuracy at low frequencies of measurements performed using the default procedure of ISO 140-4 (the same of ISO/DIS 16283-1) in test rooms with volumes greater than 25 cubic meters. About 100 previous measurements were analyzed, referring to in-situ airborne sound insulation from 50 to 5000 Hz.File in questo prodotto:
