Abstract
A sound-insulating and sound- absorbing shaped part (e.g. for vehicles or machine casings) having a foam layer is formed by placing a plastic material mixture to be foamed into a mould cavity into localised areas of which have been inserted sheet blanks. The foam embeds the blanks which define regions having different sound-absorbing/insulating properties.
