摘要:
The directivity factor of small sound sources in the direction of the measurement microphone may be determined in a reverberant room by using a pressure gradient microphone to separate the direct and reverberant components of the sound field. Experimental verification of the theory, together with analysis of the advantages and limitations of the method compared to more conventional means will be presented.
