Acoustic wave propagation in a circular cosh duct carrying a mean flow
(Acoustical Society of America, 1987-09-01)
An analysis of acoustic wave propagation in a waveguide carrying an incompressible mean flow is presented. The radius of the waveguide is taken to vary slowly as a function of axial location. It is shown that the dynamic ...
Sound transmission between absorbing parallel planes
(Acoustical Society of America, 1980-01-01)
Partially absorbing parallel surfaces can be the dominant acoustical feature of many rooms. The sound fields in such rooms are not diffuse, which causes difficulty in predicting sound pressure levels. A method is developed ...
Random vibration of laminated plates modeled within a high-order shear deformation theory
(Acoustical Society of America, 1988-09-01)
This article deals with the dynamic response of simply supported, symmetric cross-ply laminates to stationary random load. The theory of laminated plates used here takes into account transverse shear flexibility, transverse ...
Linear inviscid wave propagation in a waveguide having a single boundary discontinuity: Part II: Application
(Acoustical Society of America, 1984-02-01)
The method of match asymptotic expansions MMAE, is used to analyze wave propagation in two problem geometries. The acoustic pressure is evaluated for a waveguide having a single discontinuity in wall slope and a waveguide ...
