This report concerns the following up study synthetically based on the respective results of the questionnaires given by the members of American, German and Japanese orchestra at thirty Japanese halls during their concert tour. Focusing on the relationship between the acoustical impression on a stage and the specifications of a hall, it is needed to evaluate the degree of the inclination of the upper and the side walls of the orchestra shell which usually slant somewhat towards the audience. Such a stage in a multi-purpose hall is called the proscenium-type stage. The following became clear after the investigation. 1) A poor rating will be given for small sized stages. The stage volume should be not less than 1000 cubic meters for the orchestra performance. 2) The acoustical impression is good if the inclination is small, the reverse is also true. 3) Even in the case of larger value of the inclination, a remarkable improvement in the acoustical impression can be obtained if sound scattering objects are put on the inner surface of the shell.
