Notes	This study evaluated the lightweight impact sound of CLT (Cross Laminated Timber) made of plywood and square timber produced from domestic small–diameter larch wood. According to KS F 2810–1, the light–weight impact sound blocking performance of the CLT was evaluated by excitation with a tapping machine on the second floor and sound collection with a microphone from the lower floor. As a result, the light impact sound was 85 dB. The light impact sound blocking performance was poor, and additional studies are needed to improve the lightweight impact sound of CLT.
