INTER-FLOOR NOISE BLOCKING BLOCK AND NOISE REDUCTION DEVICE USING STEMS OF PLANTS, RED LAY SOIL, AND SOUND-ABSORBING BLOCK

摘要

The present invention relates to an inter-floor noise blocking block which is installed at a place where inter-floor noise or unnecessary sound pollution is created to block a sound leakage and attenuate and dissipate the sound. Since the sound has a weight, the present invention also uses red clay soil to form a soil panel and uses stems of plants to form a mat. And a sound-absorbing block (Korean Patent No. 5071 539) having a sound absorption coefficient of 92% is stacked with the plant stem mat and the soil panel to attenuate and dissipate sound. Also, since an eco-friendly material is used, discharge of toxic gas is minimized even when a fire occurs, and harmful waste is minimized when discarded. Also, inexpensive and easy-to-obtain materials are used.;COPYRIGHT KIPO 2019
