S/W for Sound Insulation System
Developing S/W for Sound Insulation System
We are developing S/W to design efficient sound insulation system.
We have finished ‘HONUS 2005’ which is a program to predict acoustical performance and to estimate material properties such as structure factor, porosity, flow resistivity, Young’s modulus, loss factor, etc.
Using this program, we can estimate Transmission Loss and Absorption Coefficient with macroscopic properties of absorption materials and optimize macroscopic properties of absorption materials.

Material Properties Estimation
For limp and rigid porous material
- 4 parameters estimation (structure factor, porosity, VCL, TCL)
- 5 parameters estimation (flow resistivity, structure factor, porosity, VCL, TCL)
- Optional parameters estimation For elastic porous material
- 5 parameters estimation (flow resistivity, structure factor, porosity, VCL, TCL)
- 8 parameters estimation (5 parameters + Young’s modulus, Poission’s ratio, Loss factor)
- Optional parameters estimation
