Classification:
这里是标题一h1占位文字
Product Description
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
Product features and software：
1）Obtain the 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;
2）Material TL property test： material normal sound insulation curve (transmission loss curve);
CAE modeling support: acquisition of material complex density/ sound velocity based on transfer matrix method;aterial complex density/complex sound velocity based on transfer matrix method;
3）Tortuosity test: Material tortuosity factor is obtained based on material absorption test and 1/4 wavelength theory;
4）JCA Parameters Inverse Method Test: Based on the JCA theory, Inverse identification method is proposed and identify JCA parameters (static resistivity, viscosity characteristic factor, thermal characteristic factor, etc.
5）Curve Fitting method: Moving average and Gaussian average and other smoothing methods can be chosen for curve fitting;
6）Test Project management function: Software supports project customization, material test data management, and material database built.
