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.

• Scientific Calculation and Simulation Software

The sound 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.

• Other analytical equipment

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 possible to achieve high precision and measure frequencies more than twice as high compared to conventional acoustic tubes of the same diameter.
