Flow resistance

The AcoustiFlow® flow resistance meter can be used to determine the length-related flow resistance r [Pa s/m²] or the specific flow resistance Rs [Pa s/m].

The measuring device is a cylindrical sample holder in which the flow resistance is tested by means of static air flow.

Possible materials:

  • Insulation inserts
  • Fabrics and carpets
  • Perforated sheets and plate materials
