On the sound transmission loss of finite plates with constrained viscoelastic layer

Applied Acoustics, 2019
The modal summation approach is extended to the prediction of the sound transmission loss for a finite plate with constrained viscoelastic layer. The predicted transmission loss for a single leaf plate is compared with the results given by commercial FEM

Prediction of sound transmission loss of conical acoustic enclosure using statistical energy analysis and its experimental validation

Journal of Vibration and Control, 2022
The conical shape structures are widely employed in many practical applications such as aircraft, rockets, tanks, and submarines. Prediction of sound transmission loss is often required at the design and evaluation stages of such structures.

Sound transmission loss of plate-type metastructures: Semi-analytical modeling, elaborate analysis, and experimental validation

, 2021
Recent studies on plate-type metastructures have shown promising applications in low-frequency sound insulation, as they possess a low-frequency sound transmission loss (STL) that is considerably higher than that derived from the mass law.

Prediction of sound transmission loss of cylindrical acoustic enclosure using statistical energy analysis and its experimental validation.

Journal of the Acoustical Society of America, 2022
In the present work, the sound transmission through a cylindrical shape acoustic enclosure is predicted analytically and verified experimentally. An analytical model is developed, based on the statistical energy analysis (SEA) approach, to examine the ...

The measurement of sound transmission loss of panels with small transmission loss

Journal of Sound and Vibration, 1965
Abstract The transmission room method for the measurement of transmission loss is reviewed and the lower limits of validity established. An alternative method for measuring low loss panels is described.

The incudo-malleolar joint and sound transmission losses

Hearing Research, 2002
The question as to whether the incudo-malleolar joint (IMJ) is mobile or immobile at moderate sound pressure levels (SPLs) is addressed. Referring to the mechanical properties of elastic tissue, we suggest that the IMJ is mobile at any SPL. In order to test this hypothesis, we investigated the dynamics of the IMJ in nine temporal bones by means of ...

Active broadband sound transmission loss control through an arbitrary thick smart Piezo-laminated cylinder

, 2021
The feedback control strategy is utilized for the enhancement of the sound transmission loss (STL) through an infinite thick hollow Piezo-laminated cylinder of arbitrary thickness insonified by an oblique progressive incident plane wave.
