摘要：

Nonlinear　estimation　method　was　applied　to　obtain　the　characteristic　parameters　of　porous　absorbing　material,　and　experimental　comparison　was　performed　to　validate　the　method.　In　the　experiment,　sound　absorption　coefficient　of　some　highly　porous　metallic　fibrous　samples　was　measured　and　considered　as　responding　function　to　estimate　the　static　flow　resistivity.　Estimation　results　agree　well　with　the　direct　measurement　results,　so　the　method　is　validated.
