Sound Transmission Loss of Sandwich Panels
2012The sound transmission loss characteristics of plywood based sandwich panels were investigated. Measurements were made of the sound transmission loss of a range of materials and used as a baseline for comparison while a sound transmission loss optimisation method was developed. A unique test rig was built and calibrated to determine selected mechanical

An Investigation into the Variability of Sound Transmission Loss Tests
SAE Technical Paper Series, 2007<div class="htmlview paragraph">In many cases, the results from a sound transmission loss (STL) test can differ from facility to facility. Despite the presence of standardized test specifications such as SAE J1400 [<span class="xref">1</span>], many issues can create variations in the data unique to that particular setup.

Sound Transmission Loss of Panels with Resonant Elements
Acoustical Physics, 2001Various types of resonant elements that can be used for increasing the transmission loss of panels in narrow frequency bands are analyzed. The main physical phenomena determining the transmission loss of sound waves in panels with resonant elements are studied.

Sound transmission loss of vacuum insulation panels
The Journal of the Acoustical Society of America, 2008The sound transmission loss of a variety of vacuum insulation panels (VIP) has been measured in the laboratory. Core materials of the VIP include silica, polyurethane, micro fleece, and glass fibers. Mass law behavior and minima due to bending-wave coincidence and thickness resonance have been observed.
