The paper presents application of Taguchi method in optimizing the sound transmission loss through
sandwich gypsum constructions and those comprising of masonry concrete blocks and gypsum boards in
order to investigate the relative influence of the various parameters affecting the sound transmission loss.
The application of Taguchi method for optimizing sound transmission loss has been rarely reported. The
present work uses the results analytically predicted on “Insul” software for various sandwich material
configurations as desired by each experimental run in an L8 orthogonal array. The relative importance
of the parameters on single-number rating, Rw (C, Ctr) is evaluated in terms of percentage contribu-
tion using Analysis of Variance (ANOVA). The ANOVA method reveals that type of studs, steel stud
frame and number of gypsum layers attached are the key factors controlling the sound transmission loss
characteristics of sandwich multi-layered constructions.
