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 possibility of using a two-port model to analyze the source character of an in-duct axial fan is investigated. It is found that in the plane wave region the tested fan closely resembles an ideal dipole located at the fan blades. This finding is in agreement with earlier investigations which have
Measurements have been made of the changes in the sensitivity of an outdoor microphone system when it is mounted with a B and K windscreen, type UA 0082. The measurements were made using both dry and wet windscreens in order to determine the magnitude of the change in system sensitivity for measurem
