Measurement of Young's modulus and shear modulus required for various CAE software used for calculations in SEA and FEM.
The elasticity measurement system is a system that measures the parameters related to elasticity, namely "Young's modulus" and "shear modulus," which are material parameters of the Biot model that characterize the acoustic properties of porous elastic materials.
Measure the sound absorption rate and transmission loss of the main frequency band with a single acoustic tube!
The absorption rate and transmission loss in the main frequency range (100Hz to 5000Hz) can be measured at once using a single acoustic tube. Since there is no need for multiple measurements with different sizes of acoustic tubes and samples, data inconsistencies do not occur, and the labor required for sample preparation (cutting) and measurement can be significantly reduced.
Measure the labyrinthine degree and characteristic lengths (thermal characteristic length, viscous characteristic length) required for various CAE software used for calculations in SEA and FEM.
Torvith is a system that measures the material parameters of the Biot model, which characterizes the acoustic properties of porous elastic materials, including tortuosity, viscous characteristic length, and thermal characteristic length.
Measure flow resistance required for various CAE software used for calculations in SEA and FEM.
AirResys is a system that measures the flow resistance, which is the most important parameter among the Biot parameters that characterize the acoustic properties of porous elastic materials.
Achieve wideband, high-precision sound absorption rate and transmission loss measurement with a single acoustic tube.
The WinZac 8 wideband vertical incidence sound absorption rate measurement system is a new acoustic measurement system that can stably measure wideband sound absorption rates and transmission losses with a single sample. By using 8 microphones (16 microphones during transmission loss measurements), it is capable of measuring with high precision and up to more than twice the frequency compared to conventional acoustic tubes of the same diameter.
