Overview

The C-522 series airflow resistance tester can accurately measure the important air permeability resistance of porous sound-absorbing materials. The material requirements for sound-absorbing materials are porous, loose, and breathable. Due to the porous nature of these sound-absorbing materials, their sound insulation performance is poor. For example, materials such as glass wool and rock mineral wool. The airflow resistance tester is a fast and accurate airflow impedance monitoring system that determines the sound absorption characteristics of porous materials based on the airflow resistance according to the standards of ISO9053/DIN EN29053 (DIN52213)/ASTM C522.

principle

The airflow resistance tester is a device that controls the flow rate of dry air through a sample, and measures the pressure difference generated by passing through the sample area to determine its airflow resistance and sound absorption efficiency.
