摘要: Abstract The absorption characteristics of elastic framed absorbers in combination with impervious films has been investigated. effect bonding the film to absorber and their rear surface was examined. results have modelled using established methods for predicting porous materials. a foam bonded its top most sensitive condition. Plain foams loose-laid were less demonstrate that test data used predict performance need reflect mounting conditions.
