Double glazed glass partition systems are widely used in architecture considering aesthetic look and higher sound transmission loss property. These glass partition systems are usually combination of float glass panels with air gap, laminated glass panels with air gap or combination of float glass and laminated glass panel with air gap. Laminated glass panel provides better sound transmission loss performance due to the inner damping layer as compared to float glass. These partition systems are evaluated for sound transmission loss performance as per ISO 10140-2 and sound transmission class (STC) rating as per ASTM E 413 in reverberation chamber. Laminated glass panels costly as compare to float glass. Hence design of double glazed glass panel system with float glass or combination of float glass with laminated glass having higher sound transmission loss performance is important. As per international standards, the measurement in reverberation room requires large sample sizes, specialized facility and testing time to evaluate accurate performance of glass partition systems. To save time and cost required for the measurement in reverberation chamber, need for prediction of acoustic behaviour of double glazed partition systems is having great importance. This paper discusses theoretical background of sound transmission loss property, evaluation method of sound transmission loss in a reverberation room and the simulation approach for designing double glazed partition system. In simulation technique using mathematical model approach and with the help of physical properties of glass panels prediction of sound transmission loss can be done for different configurations. The correlation between simulation and experimental results is studied for designed double glazed partition system.
