Acoustic intensity measurement in a narrow duct by a two-sensor method

The use of two pressure sensors [ Fusco , J. Acoust. Soc. Am. 91 , 2229 ( 1992 ) ] makes it possible to determine the acoustic intensity of a gas column in a duct, but the application of this method was limited to wide ducts. In this letter, the formulation of the method is modified to include narro...
