The present invention relates to an acoustic composite of non-woven materials, infused with polymeric film material, for automotive applications, and a corresponding method of formation that provides for a relatively broad range of airflow resistance and acoustic performance. Such airflow resistance and/or acoustic performance can be conveniently adjusted by material selection and method of production.
