N2 - One of design methods to obtain high sound transmission loss is double panel structure with air space and absorptive materials. To predict the acoustic performance of double panel, prediction of sound transmission loss of single panel must be performed, previously. In this study, the predicted values for four single lightweight concrete panels using bottom ash were compared with the measured values in the reverberation chamber. The surface mass densities of four specimens were 52.5, 60, 67.5. 82.5kg/m2, respectively. The result shows the arithmetical average deviations (100Hz to 3150Hz) between the predicted and measured transmission loss for one third octave band frequency were in the range between 1.1 dB and 3.9 dB. The predicted values were generally lower than measured values above critical frequency. The single-number quantities, Rw+C, were predicted in the range between 35 dB to 39 dB, and the differences of single-number quantities between the predicted and measured value were within 2 dB.
