Abstract
The study of acoustic insulation for some materials which were used in most building is investigated in this paper to reduce the noise and distribance which generated from the different sources. The object is to the best comfort to the human. A practical device is made by author and is used in this work. Some of these parts are made in the workshop of mechanical engineering and the other apparatus measurements. The concrete block, thermostone and fire block are used as walls for buildings. The glass was used with thick (4,6) mm and two layer of glasses with thick 4mm with 10 mm gap, thirospore and wood are used with thick (20,40)mm and thickness of (3,6,12)mm respectively. The comparison between above material shows that the concrete block is the best material being made from the concrete, as a comparison with other constructions. It was notice when the ration of mass to density for any material was high, the sound insulation for this material becomes excellent.
