Abstract:
Calculation and simulation of complex radiated sound field are not only the interesting at home and abroad, but also the important content of recent modern acoustics theory and application development.With the wide application of acoustics in various fields, many effective calculation of the methods have been proposed. In this paper, combining with the author′s research works, several calculations of the typical and basic methods for steady-state sound field are briefly introduced, such as the point source superposition method, angle spectrum method, numerical calculation method, analytical-numerical joint calculation method, ray method and statistical acoustic method, are described, and the corresponding calculation examples are given. The characteristics of these calculation methods are analyzed, and the problems that should be paid attention to are pointed out. Furthermore, the future development of sound field computation is prospected. The radiated sound field can be solved according to the control equation under the condition of known the characteristics and information of the sound source, and the inverse problem is not related, that is to say, the reverse calculation of the characteristics and the information of the sound source are not involved.
