SOUND ABSORBER, AND MAZE STRUCTURED SOUND ABSORPTION SYSTEM AND MAZE STRUCTURED SOUND ADSORPTION SOUNDPROOF PANEL USING SAME

摘要

The present invention relates to a sound absorber capable of easily and conveniently adjusting sound adsorption ability, and a maze structured sound absorption system and a maze structured sound adsorption soundproof panel using the same. According to the present invention, a sound absorber (120) has a hollow pipe shape, and has a sound absorption hole (h) to receive acoustic wave in the inside through the sound absorption hole (h) and exhaust the received acoustic wave in the inside. A maze structured sound absorption system is realized in a way to insert the sound absorber (120) with a small specification into the inside of the sound absorber (120) with a large specification and a soundproof panel (100) is formed by installing the sound absorber (120) inside a case (140).;COPYRIGHT KIPO 2016
