Acoustical material development with STRATI-ARTZ

Acoustical materials are define as "the materials having acoustical function". Their function is various, such as absorption, sound insulation, dumping, and so on. Historically, they were started to use in architecture, but now, they are very widely used at the place where the quietness is desired, like sound packages and interior materials in automobiles and aircrafts.
Formerly, it took very long time for the development of such acoustical materials. It is necessary to stack several materials as layers to obtain a good absorption or sound insulation performance with thin and light-weight construction. Especially, to predict the acoustical performance of such layered materials has been very difficult. The simulation software STRATI-ARTZ from Nittobo Acousitic Engineering is an evolutional software to predict these acoustical performance.

»   Ready-to-use database to start the acoustical material development quickly

With STRATI-ARTZ, a rich material database and its updating service are provided by Nittobo Acoustic Engineering. To predict acoustical performance of the material, the macroscopic parameters like "flow resistivity" or "tortuosity" are required, which cannot be measured with standard acoustical measurements. In this database, since the latest material parameters measured with state-of-the-art lab. facilities in Nittobo Acoustic Engineering are registered, you can start the development of acoustical materials once STRATI-ARTZ is delivered.

»   Quick prediction and finding an optimum composition

In STRATI-ARTZ, the materials can be stacked and the multi-layered structure can be created, and with helping the progress of acoustic modeling technology, various acoustical parameters can be predicted like normal absorption coefficient and sound transmission loss, etc. Taking advantage of simulation technology, the optimum composition to have both cost and performance can be found quickly, so you can reduce the trial manufacturing and prototyping greatly.

»   From acoustical material development to the simulation with entire product

STRATI-ARTZ can export the data as a loadable format by ACTRAN, which is a finite element CAE software provided by Free Field Technologies. The result obtained with STRATI-ARTZ can be exported to ACTRAN, or the layered structure that is created with STRATI-ARTZ can be loaded to ACTRAN. The collaboration of these two simulation software will provide you a great efficiency.
