This paper concerns the improvement of room acoustics of space habitation. When aiming at comfortable acoustical environment structure, characteristic grasp of a habitation space place is important. The acoustic propagation model in consideration of the indoor characteristic was created, and the attenuation ratio and the control effect by difference of the reverberation characteristic were verified from a basic experiment and numerical analysis. This model was applied to acoustic field control technology, and the cause that the control effect falls in habitation space was considered. The control rule which prevents an effect fall under reverberation was proposed, and it verified that this technique was effective.
