Calculation of spatial sound intensity distribution based on synchronised measurement of acoustic pressure

The paper describes a new approach in sound intensity measurement. Nowadays sound intensity has become a popular parameter which describes the sound field. Current methods which lead to sound intensity are generally based on two microphone probes or hot wire anemometry. Using the double microphone approach involves some problems with matching of the used transducers. Where the measured phenomena are excited with a known signal which is repeatable there exists a possibility of applying one microphone method. That method eliminates the necessity of matching two microphones. This goal is achieved by using resampling of measured data and synchronisation of pressure data in all measurement points of our volume of interest. Some notes on that proposed method has been presented in that paper.
