摘要: A new method, called the two source-location is described for measurement of four-pole or transfer matrix parameters an acoustic element a subsystem elements by means four-microphone technique and use function approach. Theoretical expressions are derived these shown to be identical those two-load method. However, methods conceptually different. The two-source method functionally much more stable entirely independent loading terminations. An uncertainty analysis presented used estimation possible nonequalization errors in parameters. Finally, several examples successful included.
