Several manuscripts reveal that magnesium sulfate (MgSO) is the primary substance that causes the absorption of sound in sea water. The purpose of the investigation is synthesizing an acoustical composite based on magnesium sulfate and office Paper Waste as building material component for noise abatement. The method was conducted by synthesizing and characterizing the sample to know its chemical and physical properties by using FTIR, SEM andTwo Acoustic Rooms each containing noise source and receiver. The results show that the produced composite has positif transmission loss value above STC contour standard at the frequency range between 800 Hz to 4000 Hz.
