In a church, speech intelligibility is very important together with the reverberance for musical activities. In order to obtain the primary data of a acoustical design for churches records were refereed and churches were measured in Europe and Japan. And in the base of measurements, those were judged by subjective hearing test. As some results, it has been found that the room acoustics of churches were different in a country and the reverberation time was perferred two seconds for speech intelligibility. However, although personal deviations were admitted, more long echoes were preferred for the music.
