A method of weighted residuals for the investigation of sound transmission in non-uniform ducts without flow

| Zusammenfassung: | The transmission of sound in a non-uniform two dimensional duct without flow is investigated by a method of weighted residuals which leads to a set of coupled “generalized telegraphists' equations”. Results for several duct configurations are compared with those from, respectively, a variational method, a stepped duct approximation, and an eigenfunction expansion method based on linearly tapered duct segments. |
