Sound sources in actual environments have no omni-directional feature, but they do have directivity in radiation. It is important to consider the directivity of a sound source when synthesizing a high-definition three-dimensional sound field. Therefore, we propose a simple but novel method to estimate the directivity of a sound source in a reverberant environment using a surrounding microphone array. Our method decomposes each observed signal of each microphone into an original sound signal; each impulse response is based on dereverberation technique. Furthermore, each impulse response is divided into two segments: an early response related to a directive feature and a late response related to reflections. The simulation results demonstrate the availability of our proposed method.
