【Abstract】 To derived the directivity formula of the built_up sound source in a limited space is derired based on principle of mirror image and is simulated with Matlab.Compared with the far field directivity on infinite barrier plate,the result indicates that the directivity of built-up sound source based on principle of mirror image exhibits more actually the distribution of sound field in sonochemical reactor.更多还原
