This paper analyzes the properties of material types that reduce the sound intensity by simulating differential equations with finite element method. This paper focuses on the performance of concrete and wood materials by simulating both types of materials for test room design under variable frequencies of source from 1,000 Hz to 20,000 Hz. Moreover, the simulation results compare with OSHA standards. The simulation results show that the typical human sound frequencies of no more than 5,000 Hz can be achieved. If using concrete materials can reduce the sound intensity than wood. The efficiency of concrete and wood decreased by 58.45% and 51.70%, respectively.
