The present invention is directed to an acoustical baffle that has use in vehicle interiors, such as an interior headliner. In particular, the baffle can provide improved acoustics while maintaining a desired airflow resistance and can be configured to provide for different sound attenuation characteristics at selected locations of the baffle construction.
