Numerical prediction and experimental validation of sound transmission loss for different acoustic materials

S Kirti, S Mahavir, K Y Yudhister



This paper examines the sound transmission loss (STL) through multilayer panel materials commonly used in the building industry. The acoustic characteristics of different materials and multilayer panels are studied. Experimental data for the noise reduction coefficient in the frequency range 100 to 4000 Hz have been obtained using the two room’s method. Mass theory is also used to predict the acoustic performance of these systems and to improve their acoustic performance with noise treatment.
