摘要

PURPOSE: A sound absorption plate using a transparent material layer is provided to remove noise of various types using a sound absorbing material layer which removes most of noise.;CONSTITUTION: A sound absorption plate using a transparent material layer comprises a transparent material layer(160), a sound absorbing material layer(130), and a rear surface material layer(110). Through holes(162) which accept noise are formed in the transparent material layer. The sound absorbing material layer is connected with the transparent material layer, and comprises sound absorbing holes(132). The rear surface material layer is connected with the sound absorbing material layer, and reflects the noise thorough the sound absorbing material layer.;COPYRIGHT KIPO 2010
