Abstract
This paper researches the relationship between the acoustical source of low frequency and its radiation field by using Nearfield Acoustical Holography (NAH). Simulation gives the spatial distributions of the intensity vector of two pistons vibrating with various phase differences and in the plate in mode (0, 2). Experiment shows the surface pressure and intensity vector distribution of a loudspeaker. Finally, we discuss the unstability in NAH reconstruction.
This project is supported by the National Natural Science Foundation of China and the State Key Laboratory of Acoustics.
