A shotgun microphone having sharper directivity than a conventional microphone has been studied to capture distant sound clearly. The directivity of the shotgun microphone is known to become sharper with a longer leaky acoustic tube. Thus, we developed a prototype microphone that uses a 1-m-long leaky acoustic tube, which is longer than the conventional one. We also conducted a numerical simulation based on an acoustical distribution constant circuit to develop such a shotgun microphone. The measurement results of the prototype microphone were in fairly good agreement with the simulation results, and they showed that the directivity is very narrow.
