| 内容記述 | The sound absorption coefficients which were reported hitherto are not definite owing to the condition of the reverberation chambers. When we choose the reverberation method for the determination of the coefficient, we must realize the uniform sound field in the room. To eliminate the effects of the normal modes of the room, the author used the thyratron noise as a sound source, and the non-uniformity of the distribution of the wall materials was taken into account in the reverberation formula. The experiments were pursued in a concrete box of rectangular form. The coefficients thus determined were compared with the average values that were averaged with respect to the angle of incidence and which were calculated from the normal coefficients. The author emphasizes also that the average values of the coefficients thus determined are applicable to architectural engineering. | |||||||||
