A note on the sound transmission of a spherical sound wave through a double plate structure [PDF]
JASA Express Letters, 2021 The sound transmission of a spherical wave through a double plate structure is theoretically and numerically analyzed. Unlike the plane wave incidence, it is demonstrated that the sound transmission loss due to the spherical sound wave incidence follows ...

Glazing sound transmission loss studies [PDF]
The Journal of the Acoustical Society of America, 1986 Monsanto has recently commissioned sound transmission loss tests at Riverbank Laboratories on various glazing configurations, including single thickness, air spaced, and laminated glass. Comparisons of various parameters such as STC, glass thickness, total glazing thickness, and noise reduction performance for various noise sources are made. These data
