Acoustic source data for fluid machines are of importance for calculating the acoustic field generated in a duct system and for analysis of source-load interaction effects. In this paper the problem of measuring source data for acoustic two-port sources in general is first described and critically d
Multi-load methods for experimentally determining the acoustic source data of one-port sources have been tested and critically analyzed. Special attention has been paid to the four-load method which has been reported to give erroneous results. By formulating this method in a new way it was possible
The results are presented of experimental work, still in progress at the University of Bologna, aiming to verify the feasibility and reproducibility of a short test method for estimating the sound reduction index of a party wall, according to the 1S0 proposal (ISO TC 43/SC2/WG10). The method is int
The Lewis relation is an important part of the equations that govern simultaneous heat and mass transfer processes that take place in many engineering devices. Usually, the assumption is made that the value of Lewis relation is equal to 1 which is not always realistic. As result, a new method is pre
