BOACH-HW-SITA-AF/TL Impedance Tube Sound Absorption & Insulation Test System
According to the standard：
Sound absorption test standards: ASTM E1050, GB/T 18696 and ISO10534
Sound insulation test standards: ASTM E2611 and GB/Z 27764
Introduction to product testing principles and functions：
Material absorption property test：sound absorption coefficient, surface impedance;
CAE modeling support: material equivalent complex density/sound velocity can be obtained based on double load theory;
Data format：Supports narrowband spectrum, 1/3 octave output
Data output format for CAE Software：Easy to integrate design with customer CAE analysis software;
Testing materials: PU, PET, PP+PRT, foamed metal, metal fibers and other sound-absorbing materials + heavy layers (EVA/EPDM/metal plates, etc.)
