For the purpose of knowing acoustic characteristics of a stage floor in a concert hall, vibration measurements of the floors in piano playing was carried out and the sound radiation from the stage floor was examined using the discrete calculation method. The following are revealed after the investigation on the stage floor. Distribution of the vibration in a low frequency range has a directional quality according to the direction of the boarding of stage floor. The sound radiation coefficient of the stage floor has a depression at about 125 Hz. Sound radiation power from the stage floor is greater than the sound power from the piano in the frequency range below about 125 Hz and is smaller over 20 dB in the other frequency range. Sound characteristic of the stage floor is therefore significant on a hearing sense in the low frequency range.
