In the preceding paper the acoustic radiation characteristics of a stage floor in a concert hall by piano playing was studied by vibration measurements using the discrete calculation method. The present paper represents the results for violoncello playing and the comparison with piano playing. Distribution of the stage floor vibration in a low frequency range has a directional quality according to the direction of the boarding of stage floor and the sound radiation coefficient of the stage floor has a depression at about 125 Hz, in the both playing. Sound power level radiated from violoncello comes close to the value radiated from the stage floor in piano playing. Acoustic characteristic of sound radiated from the stage floor therefore affects on a hearing sense in the low frequency range. In particular, since the sound from the stage floor in the violoncello playing only slightly contains the effect of the vibrate playing technique, the sound quality becomes considerably poor. The thickness of the stage floor is then better to be sufficiently thick.
