JD3型浮筑隔振隔音板隔声、消音效果很好:A声级能降低30-35dB (A);C声级降低17-23dB (A)。荷载增加时,隔声效果更佳。详见隔声性能表:
JD3 Floating Vibration-Damping and Sound-Insulation Board performs very good in sound insulation and sound reducing; sound level A 30-35dB(A); Sound Level C 17-23dB(A). The performance has a direct proportion to the load.
