Analytic Sound Transmission Loss Calculations for Monolithic and Laminated Glazings
The experimental measurement of the sound transmission loss of a specimen, conducted in a pair of reverberation chambers separated by a window in which the test article can be installed, according to the ASTM E-90 standard [10], is based on:

Sound Transmission Loss (TL) in decibels (dB) is an indication of how much noise a window will block out Acoustic performance is different as the frequent changes Lower frequencies (125 Hz, 250 Hz) are indicative of, vehicular traffic noise sources, while higher frequencies (500 Hz to 4000 Hz) are more indicative of pedestrian and other noise sources.
Therefore, this paper presents a study on the optimization of sound transmission loss across FGM cylindrical shell using a genetic algorithm.
