Selective conditioning for the measurement of sound transmission loss

Journal of Sound and Vibration, 1991
Abstract Multiple input modelling techniques have been applied to the measurement of sound pressure and intensity in transmission loss problems. Results indicate that the power radiated by a partition or facade can be meaningfully estimated in the presence of substantial (10–25 dB) background noise levels relative to a primary, multi-sine, excitation.

Sound Transmission Loss of Sandwich Panels

2012
The 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, 2001
Various 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, 2008
The 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.

[Sound transmission loss within the middle ear].

Zhonghua er bi yan hou tou jing wai ke za zhi = Chinese journal of otorhinolaryngology head and neck surgery, 2011
To assess the amount of sound transmission loss in order to deeply understand the mechanism of middle ear sound transmission for ossicular reconstruction and for guidance of crimping between prosthesis and stapes on sound transmission in stapes surgery.In order to get a correcting magnetic field 2 temporal bone models was used first.
