Mecanum - Noise Control Services

Static airflow resistivity meter

The static airflow resistivity meter is specifically designed to obtain reliable measurements of the static airflow resistivity (and static viscous permeability) for a wide range of materials used in noise control. The system is based on the direct method described in the ASTM C 522 standard.

Material properties

- Static airflow resistivity (Pa.s/m² or rayls/m)

- Static viscous permeability (m² or Darcy)

Applications

The Mecanum's static airflow resistivity meter has been a proven value to the world’s leading material suppliers to both the automotive and aircraft industry. It is used for:

- quality control in the manufacturing process of materials

- research, development, and innovation

- feeding acoustical prediction software dealing with sound absorbing materials

Features

The system includes one specimen holder (different sizes are available), a thin film holder, a stainless steel verification sample with its verification chart, and the Sigma-X™ software. The Sigma-X™ software assists the experimenter during the measurement and and calculate the statistics on the airflow and static airflow resistivity. The system works with disc shaped samples as those used for Mecanum’s or B&K impedance tubes, porosity meter and quasi-static mechanical analyzer. Optional calibrated samples and holders are available. See pictures of the special features on the Sideshow (left).
