Predicting the sound absorption rate and transmission loss of soundproof materials laminated with sound-absorbing and sound-insulating materials using prototype tests!
STRATI-ARTZ is software designed to predict the acoustic performance (sound absorption rate and transmission loss) of layered soundproofing materials. By utilizing a rich database of material parameters, it simulates the acoustic performance of sound-absorbing and sound-blocking materials under various conditions, which not only reduces prototyping and measurement costs, leading to time savings, but also enhances development capabilities through multifaceted considerations.

basic information
■Development of Sound Absorbing and Insulating Materials without Prototyping One of the advantages of simulation is that performance comparisons with different specifications can be conducted without prototyping. Additionally, the function to calculate the impact of various material properties on acoustic performance (Parameter study) supports guidelines for material design in relation to target performance, assisting in efficient development that does not rely solely on experience. ■Even if you do not know the material properties... If you have measurement results for the vertical incidence sound absorption coefficient, you can predict material parameters (modeling parameters for material properties) using the inverse estimation function (Single-optimizer). Of course, it is also possible to use the extensive material parameter database available in STRATI-ARTZ. Furthermore, our company also offers contracted measurement services for material parameters. ■Prediction of Sound Absorption and Insulation Performance Using Fiber Material Parameters We have implemented a model (Kato model) that predicts sound absorption and insulation performance using only fiber material parameters (fiber diameter, fiber density, bulk density). By using parameters that are relatively easy to obtain in the development of nonwoven fiber materials, we can more closely relate product development to acoustic models.
