A new method to compute sound transmission loss by acoustic FEM
Nihon Kikai Gakkai ronbunshu, 2014 In this paper, a new method to evaluate performance of sound insulating plates in closed medium is investigated by using acoustic finite element method (FEM) under such two conditions that plates are having free ends and that plates are simply supported.

Effect of Humidity on Sound-Transmission Loss [PDF]
The Journal of the Acoustical Society of America, 1964 A test program was recently instituted by the United States Gypsum Company Research Center with the cooperation of the Riverbank Acoustical Laboratories to determine the effect of ambient humidity on the sound-transmission loss of a double-leaf gypsum-board partition system. The results of this test series were quite explicit.

Simplified techniques for predicting the transmission loss of a circular dissipative silencer [PDF]
, 2001 A closed-form analytical solution for the transmission loss of a dissipative silencer with a circular cross-section is described. The silencer contains a bulk reacting acoustic absorbent which is separated from a mean gas flow by a perforated screen ...

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.
