An Improved MSA Model for Evaluating the Sound Transmission Loss of a Rectangular Plate for Diffuse Field Incidence

نویسندگان

چکیده

This paper presents an approximate analytical model for estimating the transmission loss (TL) of a finite rectangular plate in low frequency range, which is based on modal summation approach (MSA) taking into account radiation impedance and fluid loading. The mode-dependent resistance calculated using Rayleigh integral. loading taken through natural modified by added mass. results are compared with ones Statistical Energy Analysis (SEA) coupled FEM BEM. In addition, effects various vibration modes TL, way reducing calculation time discussed.

Optimization of Sound Transmission Loss of a Composite Rectangular Plate with Infinite Baffle

In this paper, optimization of the sound transmission loss of finite rectangular anisotropic laminated composite plate with simply supported boundary conditions has been developed to maximize transmission loss. Appropriate constraints were imposed to prevent the occurrence of softening effect due to optimization. For this purpose, optimization process was incorporated into comprehensive finite ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Development and Validation of Sound Transmission Loss Measurement System for Measuring Muffler Performance

Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...
